The climbing game Upset Kakumei, a derivative of daifugo, allows you switch the strength of cards. At the start of a round, each player is dealt ten cards, each of which has two values. Cards may be played in sets of X-of-a-kind of increasing value (with X=1,2,3), or a 革命 — "kakumei" or revolution — card can be played to reverse the value of numbers; otherwise, a player may pass. The game ends when someone has played all of their cards. Alternatively, you can play multiple rounds and score players based on when they exit a round.
