Kokuto Rum

Kokuto Rum is a 2–3 player card game using a 30-card deck. Each card has a white number and a black number. Players draw and discard cards, inserting newly drawn cards into their hand while trying to form sets and runs from the visible numbers. A round ends when a player knocks. Players reveal their hands, score unmatched cards, and the player with the lower score gains victory points. The first player to reach 30 victory points wins. The game includes an alternate ruleset, Shirokuro-Jan, which uses the same cards but focuses on completing scoring combinations. —description from the designer
