九九ジャン (KUKUJAN)

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!
