東のポテトマン (Potato Man of the East)

Potato Man of the East uses a deck of cards of 1 through 5, and a few wild cards, and is played as a memory game. The cards are shuffled and set out on the table in a grid.

On a player's turn, they reveal cards one at a time. When they reveal a third card, if they have revealed three of a kind, three in ascending order, or three in descending order, they can choose to stop and score or keep revealing cards. If any time time the revealed cards don't satisfy one of those criteria, the player's turn is over and the next player takes their turn.

The player with the most points wins.
