How it pays
The deck has 40 cards: cups, coins, swords and batons, each ranked 1 to 7, then Fante (8), Cavallo (9) and Re (10). Suits do not matter. Every round starts with a freshly shuffled deck and cards are not put back.
The price of a guess. Count the cards left that are higher (H) and lower (L) than the card showing. The multiplier for Higher is (H + L) ÷ H × 0.95, and for Lower (H + L) ÷ L × 0.95, rounded down to three decimals. It is shown on the button before you guess. A tie with the same rank is a push: the ladder stays exactly as it was and the tied card becomes the card to beat.
Collecting. After your first guess you can collect at any time; you receive the ladder value rounded down to a whole coin. Ten right guesses collect automatically. A wrong guess ends the round with nothing back.
| Card showing | Likelier side | Multiplier |
|---|---|---|
| 1 | higher | ×0.950 |
| 2 | higher | ×1.068 |
| 3 | higher | ×1.221 |
| 4 | higher | ×1.425 |
| 5 | higher | ×1.710 |
| 6 | lower | ×1.710 |
| 7 | lower | ×1.425 |
| Fante (8) | lower | ×1.221 |
| Cavallo (9) | lower | ×1.068 |
| Re (10) | lower | ×0.950 |
95% of fair
on every decided guess
A guess with tie chance T is worth 0.95 × (1 − T) + T of the ladder on average, so always below 100%. One guess on a fresh deck has T = 3/39.
Exact, one guess then collect: stake 10: 92.62%, stake 25: 93.44%, stake 50: 94.87% (rounding down to whole coins costs the small stakes a little more).
| Collect after | 10 | 25 | 50 |
|---|---|---|---|
| 2 right guesses | 87.48% | 88.84% | 89.52% |
| 3 right guesses | 83.48% | 84.86% | 85.20% |
| 5 right guesses | 76.10% | 76.81% | 77.07% |
| 10 right guesses | 59.38% | 59.73% | 59.70% |
Each extra rung costs about another 5%, so long ladders are the dearest way to play.
