Rules
Betting Black and White is a two-player game of bluffing with chips. Each player has ten tiles, numbered 0 to 9, and 30 chips. The even numbers (0, 2, 4, 6, 8) are black and the odd numbers (1, 3, 5, 7, 9) are white.
Setup
In secret, each player arranges all ten tiles in a row of ten slots and places all 30 chips on them, with at least 1 chip on every tile. Once play starts the arrangement is fixed.
A slot
The slots are played in order, 1 to 10. In each slot both players see the colour of the two tiles and the chips on them.
- Equal chips: both tiles are revealed. The higher number takes every chip on the slot. If the numbers are equal, each player takes their own chips back.
- Unequal chips: the player with fewer chips chooses.
- Match: top up to the same number of chips, using chips won earlier or chips pulled off your own later tiles (each must keep at least 1). Then both tiles are revealed as above.
- Fold: the tiles stay face down and the opponent takes every chip on the slot.
End of the game
After slot 10 every chip has been won. The player with more chips wins; equal chips is a draw.
Our version
- Setup runs on a 3-minute clock for both players at once. A player who runs out of time gets their arrangement locked in with any gaps filled at random (an untouched board is fully random).
- The chips on the current slot are public, as are both players’ winnings. Chips on later slots are hidden, but the total on the opponent’s later tiles is shown, since it follows from what you have seen.
- A player who cannot cover the gap from winnings plus later tiles folds automatically.
- The lower bettor has 20 seconds to decide (30 on easy). Running out of time folds.
- Matching uses winnings first, then the latest tiles, unless you choose the tiles yourself.
- Folded tiles stay hidden until the game ends; then every tile is revealed.
- A tie on chips is a draw.
- Each result stays on screen for 3 seconds, or until either player moves on.

Strategy
Your chips are your signal. A big stack says “high tile”, which can push the opponent to fold, but it also loses big if they match with something higher. A tall stack on a low tile is a bluff that only works if they fold.
Count colours. You see the colour of every slot as it comes up, and the numbers of every revealed one. Late in the game the opponent’s white tile might only be one or two numbers.
Weigh the fold. Folding costs only what you already have on the slot. Matching risks the full stack. Match when your tile beats most of the numbers their colour still allows.
Later tiles are a reserve. Pulling chips off a weak later tile to match now takes them out of a slot you expect to lose anyway. Pulling from a strong tile weakens your best slot.
Leave room to match. If you put 1 chip on most tiles and have no winnings yet, you cannot answer a big bet early on, and a forced fold hands the slot over.
