The short answer
Yatzy is the traditional Scandinavian dice game and its name is public domain. Yahtzeeis Hasbro's trademarked commercial version, first sold in 1956. They share the same heartbeat, roll five dice up to three times and fill a scorecard, but the categories and several scores are different.

The differences that matter at the table
The pair categories are the biggest practical change. In Yatzy you have dedicated One Pair and Two Pairs boxes, which gives you more places to bank middling rolls and changes how you take zeros. Straights and full houses scoring differently also shifts the math: a Yatzy full house can be worth up to 28, while a Yahtzee full house is always 25. And the upper bonus being 50 rather than 35 makes the upper section even more valuable in Yatzy.
Which should you play?
If you grew up with the Hasbro box, Yahtzee will feel familiar. If you want the traditional European rules, with more categories and a bigger bonus, Yatzy is the one. Our free game uses the authentic Yatzy ruleset.
Frequently asked questions
Is Yatzy the same as Yahtzee?+
They are close cousins but not identical. Both use five dice and three rolls, but Yatzy has extra pair categories, scores straights and full houses differently, and gives a larger upper bonus. Yahtzee is Hasbro's trademarked version with its own fixed scores.
Why is it spelled Yatzy and not Yahtzee?+
Yatzy is the traditional spelling of the public-domain Scandinavian dice game, common across the Nordic countries and Europe. Yahtzee is a registered trademark owned by Hasbro. Free online versions use the Yatzy name and rules to stay clear of the trademark.
Which version is harder?+
Yatzy has more categories and the pair boxes add decisions, so there is slightly more to manage, while its higher bonus rewards upper-section play more. Yahtzee's joker and bonus-Yahtzee rules add their own complexity. Both reward the same core skills.
