オクトパスオーダー (Octopus Order)

It’s a card game played with eight types of cards, numbered 3 through 10. You can use it to play things like: a trick-taking game that feels like dominoes, a game where you’re not allowed to rearrange your hand but can add one card, a Daifugō-style climbing game where points come from majorities in the cards you’ve won, a two-stage press-your-luck/flipping game, and more.
