The deck
Thirteen ranks from two to ace, drawn independently each turn with equal probability, in one of four suits. Suits are decorative and never affect the outcome.
A single card faces up. Call whether the next one will rank above or below it, then watch it turn. Correct calls extend your run and each additional link in the run is worth more than the last.
Shuffling the deck…
Thirteen ranks from two to ace, drawn independently each turn with equal probability, in one of four suits. Suits are decorative and never affect the outcome.
The first correct call is worth twenty chips, the second thirty, the third forty, and so on. A wrong call ends the run and returns the ladder to its first rung.
If the next card matches the rank on the table it is a push. Nothing is added, nothing is lost, and the run continues untouched into the following turn.
New tables arrive slowly because each one has to justify itself without a stake attached. Three are currently being drafted on paper.
A single-player card sequence in the manner of a solitaire, scored by how few turns you need to clear the felt.
A small wheel of thirteen positions with the entire distribution printed beside it, deliberately unhurried.
A memory board using suit emblems, intended for visitors who prefer recall to probability.
The escalating ladder exists to make a run feel like an achievement rather than a stream of small rewards. It also demonstrates something useful: a long run is remarkable precisely because each additional correct call is roughly a coin toss.
If you reach a run of ten, you have done something with odds in the neighbourhood of one in a thousand, and you have done it for free. That is the entire prize, and we think it is a decent one.
