Idle hands are the devil's playthings, and yours are the laziest of them all.
In the must-follow trick-taking game Idle Hands, a.k.a. 悪魔でお仕事, the led suit is determined by an extra card played to the trick from among a player's face-up mission cards. The highest card of the led suit wins all the cards, then adds the mission card to their hand! Every trick is worth points, but this isn't necessarily a good thing since the 4s and 8s are worth their face value in negative points.
At the end of the game, whoever has the most points — or more frequently the fewest negative points — wins!
