Catch the Mistake

How the mode behaves

Starting a run

audition.html — pick the games, set hands per game, hit start

Built

All seven — both blackjacks, all three poker sims, pai gow, baccarat

Session length

Set once, applied to every game in the run

Between games

Each leg's scorecard hands off to the next; a combined one waits at the end

Mistake rate

25% of hands by default, on a settings slider

Per hand

At most one mistake, by one player

The flag

A red ! box pinned to the right edge, live all session

Calling it

Click !, click the bet, then make one of two calls — fix it or floor

Fix it

Right answer while you're still on it — the player corrects the bet and the hand plays on

Floor

Right answer once the game has moved past it, and always for a foul or a busted stand

On a wrong call

Right bet, wrong call logs as wrong call; wrong bet is a miss, clean hand is a false flag

Chips

Never appear — every bet rides in from the players' side, clean or rigged

Help mode

Never available in audition mode

End of session

Scorecard: caught, missed, false flags, hand-by-hand

Rows marked ★ are the ones you called out by name. Every entry below is injectable at a real hook in the existing code — nothing here needs a rewrite of the sim it lives in. The catalog is deliberately longer than any one session uses: the picker shows the issues for the spot you point at plus plausible decoys, so the dealer can't win by memorising a short menu.

Table limits are provisional. Every "under the minimum" and "over the maximum" row reads its numbers from one constants block per game. They're currently inferred from each sim's bet generator — when your min/max sheet arrives it drops straight in and every limit row follows.

Timing decides the call. Catch a bet that's wrong while you're still on it and the player simply fixes it. Let the game move past that point and it stops being yours to correct — that's a floor call. Where the window shuts depends on the game: in blackjack the bets close when the cards come out, insurance when the line closes, and a double or split when the action leaves that seat; in the poker sims a bet is yours until you start settling that seat, since the whole hand is already costed when the curtain lifts; in pai gow it runs right through the build phase until you settle the seat; in baccarat it closes the moment a card leaves the shoe. A couple of things are never yours to put right however fast you spot them, because there is nothing to correct at the table — a pai gow foul, and a pitch hand that turns over above 21. Those are marked Floor only.

Deliberately out of scope. Bet increments (players may use $2.50, it's just rare) · putting a bet in the wrong circle · betting into a neighbour's spot · anything involving the player's hands — touching or covering cards, two hands on a hand, passing cards, bending a card · anything the player verbally claims about a payout · insurance taken after the line closed or with no ace showing · capping and pinching — a player adding to or pulling off a live bet. All real, none of it in the simulation.

Missing is a bet that can't stand as placed — a side bet with nothing behind it, a mandatory bet that never went up. Change is not an error at all — it's a duty. A player who tosses $25 at a $5 progressive is buying in: leave the buy-in up, change the rest back. Short of the buy-in is the mirror image — $2.50 on the $5 Red doesn't play, so it goes back. Either way the dealer has to notice, and both ride the same flag flow. (A Blue progressive can't be short: the buy-in is $1 and there's no chip under it.)
