Twenty-one

How to play: It’s literally blackjack—play and try to get as close to 21 as possible without going over. Whoever gets closest wins, and the point difference determines the damage taken.

Explore the "Twenty-one" casino—where defeated opponents turn into cards—and defeat the owner on the fourth floor; battle bosses and modify your cards with absurd, wacky, and chaotic powers.
