So I played. The balls were still locked, and I even found the multiball start. This put together a lot of points fast. I started getting congratulations, and I double-checked my score, then let the ball drain. The bonus kept counting, rolling up surprisingly long a while.

I'd won.

The import of this might not be obvious. For all I talk about pinball around these parts, and for all I've talked about [livejournal.com profile] bunny_hugger's successes --- she's won the B Division at the Marvin's league, and got a string of trophies from the Lansing league --- and for all that I do pretty well in league play, the fact is I've been lousy in tournaments. Usually I bomb out quickly. On rare occasion I win one or two matches before being defeated. On a few occasions, such as the Amazing Race side tournament at the State Championships, I get far along. But I finish out of the money every time. I'd had success as one of a pair in Zen Tournaments, but as a solo player? Never.

And suddenly I had. For the first time in my competitive pinball career, I won a solo trophy.

B Division, yes. It has struck me part of my trophy drought was that I'm good enough to qualify among the state's top players, but not good enough to reliably beat them. So my slow start maybe put me in easier waters. Still, MWS is certainly better than me. The father who'd tilted out might be; it's hard to say. Well, it came out nicely for me, anyway.

Bill had homemade trophies, carved wood things, for the top three winners in A division, and for the lone top winner in B. He'd had the time to paint the carvings of flippers in the trophy for B, so I have one that stands out even among its partners.

There'd be some time yet before the A Division finished its playoffs. It had more people, and more better players. We stuck around of course. [livejournal.com profile] bunny_hugger are great ones for sticking around and trying to help with cleanup and all that. And some of our better friends were in the running for the championships in A Division. Plus, there's trying to figure out how to play Pinball Magic to do.

So we'd stick around to the reasonable end of the night, and take home surprisingly large amounts of the potato salad and spaghetti salad and all we'd taken there to start, and talk about just how wonderful the whole day was and how glad we were to be there. On the way out --- well, there was that Jurassic Park machine. It had been sitting in the garage, not used in tournament play for some reason. MWS had turned it on for a game before he left. [livejournal.com profile] bunny_hugger took a turn on it herself. I don't remember if I played. I suspect not, since I'd had a satisfying game inside and I like leaving on a high note. I believe we amused our hosts with stopping for one last little game before heading back home. I'd certainly be.

He tilted.

I was surprised. He was surprised. Everyone was surprised. He maybe had slapped the machine a little hard, but nothing out of the ordinary, and nothing deserving of a tilt. But the tilt mechanism can't be argued with either: it ruled he had given the machine too strong a push and that was that.

The tilt mechanism in a pinball machine is a simple yet clever contraption. Most pinball hardware is. In this case it's a pendulum: a rod, dangling from a wire, within a metal ring. If the rod touches the ring, it makes an electrical contact. Meet the necessary number of contacts and you get a warning, or a tilt. This is why gentle nudging is preferred; it avoids making the pendulum swing too much. This is why when a machine gives a warning, players stop nudging, and why after a tilt they give the machine time to settle. They don't want to get an unfair extra tilt out of it.

So the next player, the one I didn't really know, waited. And waited. If you know where to look in a pinball machine you can spot the pendulum bob; it's usually on the left side of the case, kind of near the flipper button. If that's too hard to spot, you can swing the coin door open, because this was a machine in a guy's home and he didn't have that locked. The tilt was not just tight; it was taking forever to settle.

We had some serious debate here: was the tilt fair? Not really, although it seemed within the bounds of fair play. But if it tilted the other guy's ball too --- that's considered a tilt-through, and it normally disqualifies a player who tilted. But a tilt-through normally happens right away. We waited several minutes and the tilt bob was still swinging. Should we consider writing the table off as defective and replay the round?

Well. Of course. I had a selfish interest in saying no, we'll take the table as it stands. I'd probably win the match and tournament if we did. On the other hand, I don't want to be unfair if I can help it. And the other guy was taking a risk if he played. We did speculate whether the tilt bob could be safely stopped, but concluded that there wasn't any way to do that.

The other guy decided to risk playing, but with the caveat that another unprovoked tilt --- and I do want to emphasize, everyone playing or watching, me included, agreed the first tilt was unjustified --- would get the machine thrown out. And so I was again a vulture, hoping that the other guy played out a ball that lasted too little time for anything to go wrong, so I could put up a couple thousand points, hopefully, and win.

And that did go as I hoped. The other guy played a little bit, not enough to overtake me, nowhere near enough to catch the father. He didn't tilt, or get warnings or anything. The game would be up to me, on the one ball, to catch the father's score perhaps and win or lose on my own effort.

Back to the tournament. After a strong start [livejournal.com profile] bunny_hugger was becalmed just short of the fifteen points needed to qualify. I started slower, but kept going. People kept qualifying ahead of us. The top eight, the A bracket, got filled up. We kept plugging away. MWS qualified. And then, finally, I did well enough in our pods to get the fifteen points and qualify for finals.

[livejournal.com profile] bunny_hugger didn't.

Now, on the one hand, both of us had qualified for finals in either the main or the side tournament. And she had had several fantastic games, including absolutely crushing people on a round of Pinball Magic. She found one shot she could repeat, and build up to an incredible points payout. I believe her score that game more than doubled the combined scores of everyone else in her group, and that group included the guy who had won the Michigan State Championship. On the other hand, she had missed the main tournament, and that hurts. And side tournaments are never worth as much as main tournaments. It would happen that, despite her doing better in her tournament than I did in mine, she'd get about half the International Flipper Pinball Association credit.

I didn't get into the A division. I was part of the quartet of people who'd get to compete for B division. It'd be me, MWS, the father of that father-son pair (the son was in A division), and another guy from the Detroit area whom I'm not sure we had ever met. Competitive pinball records indicate he was at the Amazing Race tournament the week before, but that's not much guidance about who he was.

We would go into a three-game playoff, following rules akin to what they do at the top-level pinball competitions. And the games would be scattered all over; after two matches me, the father, and MWS were surprisingly close to tied. It would all come down to the last game, which the random draw made out to be ... Mars, God of War.

I would have a chance on this. Mars, God of War, a solid state machine, levels playing skill. And I'd put some time on it, as well as staring intently at other people playing, to work out some of its secrets. Knock down every drop target. Also, I'd worked out where to shoot, at least, for two- and three-ball multiballs. Those wouldn't have jackpots, but they'd offer the chance for big scoring potential in vey short order. I'd be the last player, too, which is always a psychological advantage. The last player doesn't have to be the best he can; just, good enough, and the last player knows how much that enough is.

I had a fair first ball, including locking a ball but not releasing it for multiball. That's potentially dangerous since on an older game like this, someone else could unlock the ball, gaining multiball for themselves and stealing yours. But nobody did, and I felt relieved. The second ball went better, as I remember it, although again I locked a ball without releasing. Still, I had a pretty good lead.

MWS closed out on a lousy ball that locked him into fourth place. The father played. I've since realized that he is a single-ball player; he can often win, but it's on a single outstanding ball rather than a couple consistently good balls. I think I apprehended the risk here because I did feel like the score gap he had to overcome wasn't nearly big enough. It wasn't; his score just barely exceeded mine. And I thought about what I could do to rack up points quickly when my turn came. And then ---

PS: A Leap Day 2016 Mathematics A To Z: Kullbach-Leibler Divergence, a mathematics thing I didn't know about two weeks ago, but which I've learned something about for now.

In the 90s Capcom got into making pinball. This is not so weird as you think. Pinball was no longer subject of public scorn or moral panics. Computer and display technology had opened up great new avenues of game design. And an incredible streak of all-time classics, unmatched before or since, were made then. But Capcom didn't last long in the market. Video games almost necessarily have lesser maintenance costs. Redemption-ticket games almost always have higher profits for the maintenance. And under the mad genius of Python Anghelo the pinball division sank ungodly sums of money into an obvious non-starter called Zingy Bingy, a Habakkuk of a project I will not describe here because you really need to look up an article about it while you're at work and surrounded by grim-faced people wondering what all the snickering is over.

One of the short-lived division's games was Pinball Magic. It came out surprisingly close to the Williams game Theatre of Magic, in that way sometimes rival companies just make the same theme thing at the same time for some reason. Apparently stage magic was just in the air. Theatre of Magic is one of the solid favorites of the 90s, no doubt because it appeased the devilbunny community. It's everywhere. Pinball Magic is not. The Silverball Museum advertised it would have one, but if they did, it was gone before we could ever visit. Bill had one. We'd been looking forward to the chance to see one. And nearly everyone at the tournament would be playing pretty near their first games ever on the table.

Pinball Magic has as its theme some of the classic styles of stage magic. Your classic guy-in-tuxedo-and-top-hat, your showy Las Vegas glitter bomb, your guy in Vaguely Oriental garb that's let's just say problematic, your wizened old guy in robes, all that. Different parts of the playfield correspond to different performance styles, and the modes of the game are to make shots in the appropriate corresponding areas.

There's a lot of clever, innovative thinking in the game. For example, right out of the plunger, the ball is launched onto into a wire-frame ramp. Normal enough. This one has a loop in it. That one I've never seen before. If you plunge just the right strength, the ball makes it halfway through the loop and drops into a top hat prop. That's not just novel, that's clever. Brilliant, even, given that it's the skill shot for the first and third balls. The second is a different shot.

On the playfield is a ramp that leads to a hand, holding a wand, itself leading to another ramp. There's a magnet inside the wand. If you shoot the ball there, it will hover on the underside of the wand, wobbling its way down that path. It looks magical. It's a fun shot to start with, and to have the game's flow reach a wondrous point like that ... well, it's grand. Innovative and clever. Great job all around.

The game was like that all around. We kept encountering new and clever and, generally, funny bits of business. Many of them included new uses of by-then standard tricks like electromagnets and ramps. We never quite felt sure we understood the game, but we got some good hypotheses going. We'd love to play more. And yes, the game did bow at least a bit in the devilbunny direction.

Even if the whole day were a fiasco --- which it wasn't --- the chance to discover Pinball Magic would have made it worthwhile.

So, the main basement tournament: there'd be a qualifying period and a finals. To qualify groups of four players would be randomly drawn and assigned a table. Whoever scores highest got four points, second-highest two points, third-highest one point, and the bottom-scorer got nothing. Reaching fifteen points qualified one for the finals. Qualifying would carry on until the seeding spots were full.

So there's obviously always an advantage to winning your group. But anything besides losing the group gets you a little closer too. And the social side of pinball would produce some odd conflicts of desire. It's more fun to play with better friends, if nothing else for the fun of commiseration. Our closest pinball friends, though, are MWS and CST. They're not people we can't beat, mind you. But generically, if we're all playing at our average, that puts me and [livejournal.com profile] bunny_hugger in third and fourth place and that won't get us anywhere. So we both wanted to get paired up with each other, and with our friends; but we also wanted to get grouped with people we could beat.

If not a group we could beat, then, at least we might get a table we could win on. There was always Mars, God of War, for example, a 1981 solid-state table. That's much more a coin toss than, say, The Avengers, another boring modern Stern. And even moreso than would ordinarily be, too. Besides its sound being distractingly weird --- almost all silent except for low, angry growls --- its tilt was alarmingly tight. People got tilted without obvious warning or provocation. There was talk of taking it out of rotation, which never came to pass, and I'm glad for that. Or there'd be perfect mysteries of games, such as Pinball Magic. We had heard of this table, but never seen it. More on that one anon because it deserves some special attention.

We'd get assembled into groups and go off and play and come back together again. It felt like I kept getting paired up with MWS, although that surely happened less than we think. I kept not getting Mars, God of War, to my disappointment because I was pretty sure I'd be in tune with it. [livejournal.com profile] bunny_hugger leapt ahead in points pretty quickly. I think she was up to ten points before I was even at five. I seemed to keep getting assigned Road Show, over and over and over.

[livejournal.com profile] bunny_hugger would also get dropped onto Twilight Zone a lot. Twilight Zone is one of the beloved games of the 90s Golden Age of pinball. It's got a lot of modes. It's got some great blends of humor and strategy. It's got a wizard mode that's second to none. It's also brutal, particularly with a bumper field near the left outlane that is just death. You can make a skill shot perfectly, only to be sent into the bumpers and from there into the cornfield. If you are in tune with the game, it can be a masterpiece. If you're not, it's rapid death. And [livejournal.com profile] bunny_hugger got becalmed in a seemingly endless string of Road Show and Avengers and Twilight Zone games that would just not give her anything to do.

So in the later rounds of qualifying she'd rack up dreadfully few points. I would get a string of disappointing third-place finishes too. One that I remember burning me was a Metallica game in which I just could not hit anything for anything. After bombing out on that I took time between rounds to play it again (legitimate; many people were practicing between rounds, or getting in time on unusual games), and put up a perfectly crushing game, the sort that would've won my previous group if everyone else's scores were doubled. So it goes.

And so the afternoon went: us stuck just below the threshold fifteen points, increasingly desperate and struggling against ever-more-desperate competition, as the available slots in the finals filled up, one by one.

Now to continue the Video To Go-inspired tour of stuff that's not there anymore. Technically this stuff is still there, but that's just because they haven't got around to demolishing it, what with winter being a bad time to do serious work like that.

Back entrance (and parking lot) for Emil's, the oldest restaurant in Lansing and doomed by the developer choosing to knock down everything and put up a horrible four-storey mid-value commercial zone from SimCity 2000 instead. The restaurant dates back to a fruit stand, apparently, that's been in that spot since 1921 as promised.


P1370908.jpg

Mural promoting Emil's that is not, of course, on the side of the Emil's building. The block's a string of buildings close up against one another, so the exposed side is a couple structures down. This is actually the side of a barber shop that also got run out by the decision to demolish the block. There's a couple building side murals in the area, part of giving the neighborhood some character.


P1370911.jpg

On the right, the long shot down the doomed block, and I just now thought to wonder if the trees on the sidewalk are doomed or not. Hm. Opposite the street are a bunch of buildings that'll be staying as they are, far as anyone can tell. The blue front with the pyramid opening is the hipster bar where our local pinball league meets.


P1370920.jpg

Emil's, on the day before it would close. I didn't go in. The white building with green trim past it was, most recently, a short-lived and it turns out unlicensed music venue that exploded in a fit of charges of broken yet mostly oral contracts. The red-bricked building past that used to be, if I have this right, a yarn store and before that a comic book shop that's kind of moved across the street and merged with the hippie bookstore.

Emil's front door with some nice partly stained windows. At a neighborhood meeting intended to manufacture consent for the lousy new replacement, Emil's owner said it was time for the long-lived if, admittedly, declining restaurant to move up to the next step: making prepared meals for sale in the city farmer's market.

A longstanding pinball superstition has it that your first game on an unfamiliar table will be your best game on that table for a long, long while. It's easy to understand why. The first time on a new table you just try to keep the ball alive. The second time you think you've worked out some strategy, and try for that, and maybe it's not right and maybe you're focused so hard on one shot that you miss everything else that makes points and so on. Eventually you recover, but there does sure seem to be a nasty dip after a good first game.

[livejournal.com profile] bunny_hugger put up a great game on Hi-Score Pool, the strange pinball machine with a nearly-concealed playfield which was the side tournament's game. There'd be open qualifying, playing as much as you had time for, until about 6 pm, with the highest eight scores going on to finals. Her first score started out as maybe the second-highest recorded. It would drift down a little bit, here and there, but never so much. It would always stay much higher than my highest score, even after I started to work out some of the ways to play this strange game. She even mastered advanced skills like bounce-passing on the large circular disc that catches and launches the ball and takes up the space between the flippers. I don't think anyone else managed that.

I would never be on the leader board. I got to like the game, and worked out what I thought a winning strategy for playing it. It's an electromechanical game, which rewards slow playing and letting the ball roll itself out. But the flippers also don't allow for trapping the ball, bringing it to a stop and aiming it. Also there's no clear direction to shoot the ball; you have to infer where the targets might be. Some people tried to overcome this by squatting low as possible to peer under the board covering the playfield. I realized the guidelines on the playfield were basically right. But I didn't get the chance to play my way back into competence.

[livejournal.com profile] bunny_hugger watched the spreadsheet with the top eight scores, with increasing misery, as the cutoff hour approached. One person and then another recorded a slightly higher score and pushed her down. At the deadline she was sitting there on row number nine.

The thing about spreadsheets is that if you use them like a normal person, Row 1 will have headers. Like, this spreadsheet was headlined 'Name' and 'Score'. So [livejournal.com profile] bunny_hugger was the 8th-highest scorer in qualifiers. She was in for the side tournament.

Finals for this took the 5th through 8th place finishers and had them each play a game of Hi-Score Pool. The lowest would be eliminated. The fourth seed would join the survivors, and they'd play again. The lowest would be eliminated, and the third seed join, and so on. This scheme's designed to generate the greatest number of meaningful games the winner may have to play --- the metric that the Professional and Amateur Pinball Association uses to judge a tournament's point value --- without taking forever to play. If [livejournal.com profile] bunny_hugger could just beat anyone, consistently, she could become one of the final four. And an electromechanical game is a coin toss to start. A bizarre electromechanical like this even more so.

She got eliminated the second round, and came in number 7 in the tournament. She'd be beaten by some great people, including the people who came in #1 and #2 in the State Championship the weekend before. And she beat a lot of great players, including CST, MJS, Bill, me, and both that father and son pair mentioned in the State Championship report. But still, there's always the hope of doing just that little bit better still.

So now I'd like to do something a little different and talk about a pinball event. This would be called Bill's Basement Tournament. Bill is one of the folks in several of our pinball leagues. He's got a good dozen or so pinball machines in his house. He opened it up to two dozen people. [livejournal.com profile] bunny_hugger bought tickets to it before asking if I wanted to go; she feared the tickets being sold out. I was interested though, sure.

We brought some food. The meals were going to be a bit potluck, which implies people who're vegetarian need to take steps. We got some spaghetti salad and potato salad from Westlund's Apple Market, and some artichoke salad from Horrock's, and were nearly the only people to eat them. Maybe people were suspicious of unfamiliar-looking foods. Maybe they were just wrong. Let them be.

His house was a nice, good-sized suburban thing that could probably fit ours in its garage. He's got a furnished basement, which somehow some people can manage in Michigan despite the nearly 900 percent humidity in below-ground rooms. And he couldn't fit quite all his pinball machines downstairs. Two were exiled to a guest room up top --- Mars, God of War, a late 70s machine which happened to have a broken audio chip so it sounded like an angry demon; Black Knight, the early 80s classic, but too broken to play --- and one to the garage, Jurassic Park. That mid-90s game would be out of bounds for the tournament for reasons I never quite got straight.

As often with this sort of thing there'd be a main and a side tournament. The main tournament you'd qualify for by playing in randomly picked groups of four on randomly picked machines. For each win you'd get 4 points, a second-place finish 2 points, a third-place finish 1 point, and a last-place finish 0 points. Get to 15 points and you qualify for finals.

The side tournament was on Hi-Score Pool, a really weird-looking game. Its playfield is almost totally obscured from the flippers. You shoot out into the dark, hitting concealed targets that represent pool balls. Hit the full set of pool balls and you get a nice big score, but, the flippers are small and far apart, and the tilt on the game touchy. Also it's a game almost nobody knew how to play. This would be challenging.
