Roll five dice up to three times. Score each roll into a category. Chase the high score or play with a friend.
Koro Koro 🎲
Roll five dice. Score your best. Beat your best.
How to play
- On your turn, roll all five dice.
- Set aside any dice you want to keep, then roll the remaining dice — you can do this up to two more times.
- After your final roll, choose a scoring category on your scorecard to assign your dice to.
- Each category can only be used once. The game ends when all categories are filled.
- The player with the highest total score wins.
Tips
- Fill the number categories (ones through sixes) early to guarantee some score in them — don't hold out hoping for a perfect hand.
- Aim for the bonus: scoring high across the six number categories earns extra points.
- Chase the highest-value combinations (full house, straights, five of a kind) early when you still have all your rerolls available.
About this game
Koro Koro is our version of Yahtzee, the classic dice game published by Milton Bradley in 1956. "Koro koro" (ころころ) is a Japanese onomatopoeia for small round things rolling — which felt exactly right for a dice game on a site with a Japanese sensibility. Yahtzee itself descended from a game called Yacht, invented in the 1940s, and before that from much older dice-scoring traditions going back centuries. The combination of luck and strategic decision-making — knowing when to settle for a modest score versus pushing for the big combination — gives it lasting appeal across all ages. You can play solo to chase a high score, or take turns with a friend.
