九九ジャン (KUKUJAN) is a board game released in 2022 for 2–4 players, 10–15 minutes per game, and ages 6 and up. It was designed by Toru Oyama and Aiko Oyama.
Incorporating elements of multiplication and mahjong, the easy-to-understand rules of Ku-Ku-Jan involve collecting the 99 numbers that exist in the same row or column. You can study multiplication while having fun. Can you figure out which row or column a number is in just by looking at the numbers? There may be numbers that exist in more than one row! While there is an educational element to the game, the strategic nature of the game, in which players aim for a tier that does not cover the other player's discarded cards while considering the opponent's discarded cards, makes it an interesting strategy that adults can enjoy as well!
九九ジャン (KUKUJAN) supports 2–4 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for 九九ジャン (KUKUJAN) is 10–15 minutes. This is the publisher’s estimate for a full game.

Setup and teaching time are not included in this estimate.
