Play Yatzy Online — Free, Two Rulesets, With a Coach
Classic five-dice Yatzy against two computer opponents, with something most versions skip: two authentic rulesets. Play American rules (13 boxes, the +35 upper bonus, joker rules) or Scandinavian Yatzy (15 boxes with One Pair, Two Pairs and the fixed straights) — scored correctly, not relabelled. A built-in EV-optimal coach computes the mathematically best dice to keep and box to take. Free, in your browser, no download and no account.
How to play
- On your turn, roll all five dice, then tap dice to hold the ones you like and reroll the rest — up to three rolls total.
- Then score the dice into one open box. Each box is used once, so choosing where to bank is the game.
- Fill the upper section (Ones–Sixes) to 63 for the bonus.
- Highest grand total when every box is filled wins.
American vs Scandinavian rules
They are genuinely different games. In American, three/four of a kind score the whole hand, Full House is a flat 25, and straights are any run for 30/40. In Scandinavian, three/four of a kind score only the matching dice, Full House is the sum of all five, straights are the exact 1-2-3-4-5 and 2-3-4-5-6, and you also fill One Pair and Two Pairs. This build implements both properly.
A coach that plays the odds
Tap 💡 Hint and the coach runs an expectimax over your remaining rolls: it highlights the best dice to keep and names the best box to score, with the expected points. It reads only your public dice — the same information you have.
