user

My buddy runs a bar. I told him I'd build him something for Thursdays. He's the one talking here — I just write down what he says and hand it to you.

The game

It's not real pool. Three balls on the table, you shoot until all three are down, and we count how many shots it took you. Low is good. Everybody takes a turn, then we go around again — that's a round.

Twenty bucks to play. You start with five chips. Take more than four shots to clear the table and it costs you a chip. Out of chips and you're out, go back to drinking. Last one with chips left takes the pot.

There's a clock on your turn — a minute, minute and a half, we've never really settled it. Clock runs out and you're not at the table, that's a chip.

The night

It's a Thursday. Nine o'clock, everybody's had a few, the jukebox is loud and half the room is outside smoking. Twelve, sixteen people usually, however many show up. It runs two, three hours and nobody's in a hurry.

Last year I ran the whole thing on a legal pad and it got away from me around round four. Two guys arguing with me about what they shot, me trying to remember whose turn it was, somebody's beer on the pad. Never again.

I'm running this off my phone, one-handed, standing at the table with a beer in the other. There's a TV over the bar and that's the only screen anybody in the room can see — from across the room, in the dark, so it's got to be big. People want to know where they stand without walking over and asking me.

My phone's on 15% by ten. The bar's wifi is the bar's wifi.

The money

Twenty a head, all of it in the pot. Winner takes it — mostly. We kick a little to second. And there's a side thing we do for whoever's shooting best early on, I never wrote that part down properly.

The app doesn't hold the money. I do. But at the end of the night it has to tell me what I owe who, and I'm reading that off my phone with sixteen people standing around the table.

What I want

Two pages.

The console — the thing I run it from, and the thing that goes up on the TV. Open it and there's already a game going. I'm not typing in twelve names to find out whether it works.

The playback — a separate page that plays a whole night through, start to finish, so I can watch it work before Thursday. One step at a time, a step being one thing happening, with the scorecard filling in as it goes and a slider for how fast it runs. I want to slow it down, back it up, and read what just happened. Show me the way a night actually goes.

The playback runs the same rules the console runs. If the two of them drift apart, the playback is a cartoon and it's no use to me.

House rules

Two files. Each one a single HTML file — everything inline, no CDN, no external stylesheet, font, script or image. data: URIs are fine.
No libraries. No frameworks.
No network at runtime.
No localStorage, sessionStorage, cookies or indexedDB — these run in a sandboxed frame where those throw.
Exactly two fenced html blocks: the console first, the playback second. Leave yourself room for the second one.

Answer in exactly these sections

What you filled in

I know I wasn't clear about everything. Everything you had to decide for me, one line each — what you decided and why. Short.

The console

The first fenced html block.

The playback

The second fenced html block.

What'll go wrong

It's Thursday, it's nine o'clock, and I'm running this for real. What comes up that this doesn't handle? Be straight with me. I'd much rather hear it now than find out with sixteen people around a pool table and three hundred dollars sitting on the bar.

assistant

What you filled in

Turn order: Fixed order each round; eliminated players are skipped, and the night ends immediately when one player has chips.
Shot scoring: A clear takes 1–99 shots. Anything over four costs exactly one chip, however many shots it took.
No-shows: A no-show costs one chip and forfeits that turn; it does not also record a table score.
Clock: Ninety seconds, automatically restarted each turn. Zero is only a warning—the operator decides whether the player was away.
Runner-up: The last player eliminated gets $20.
Early-shooting prize: $20 Hot Start, for the lowest round-one clear. Ties split the $20, including odd cents.
Winner: Gets everything left after those two prizes. Anyone winning multiple prizes gets one combined payment line.
Opening game: A fictional twelve-player demo starts in round four; New night replaces it with a real game.
TV: Included as a large same-screen view and a live pop-out scoreboard; there is no device-to-device networking.

What'll go wrong

A refresh, crash, closed tab, or dead phone loses the night. There is no recovery file or backup. Bring a charger, keep the phone from sleeping during operation, and keep a paper fallback. At 15% battery, this is the biggest risk.
The TV is not independently networked. The pop-out only works on the same browser/display setup and may be blocked by the sandbox or phone. Otherwise, TV mode takes over the operator screen. Test the exact phone, cable/casting arrangement, and TV before Thursday.
The clock cannot tell whether somebody is actually at the table. It never assesses the penalty automatically; you still have to make that call and tap no-show. There is no loud audible alarm over the jukebox.
Corrections are limited. Undo can back up through turns, but anything after the corrected turn must be re-entered. There is no arbitrary score editor, player rename, late joiner, manual turn reorder, or midgame substitution.
The game has no time cap. If good players keep clearing in four or fewer, it can run far beyond three hours. There is no sudden-death rule, agreed early finish, or winner-tie settlement.
The money rules are now explicit, not negotiable in the app. If your crowd expects a different second-place prize, Hot Start period, tie handling, or payout for someone leaving early, settle that before collecting the $20. The app only calculates; it does not track cash handed over.
