Red Hand

Red Hand is a simple reaction game for two people on the same device. The description calls it a hot hands app and presents it as one of the better two player games for a single screen.

It is a hand slapping game, and the idea is to react faster than your friend. The source says it is meant to improve reaction time, and it is easy to start since the rules are short. Look at the instructions at the start for what each player does.

This is a good pick for a break between longer games or when you only have a few minutes. A tip is to keep your eyes on the screen and stay relaxed instead of tensing up, since tight hands are slower. If you like this one, try Red Hands 2 Players.
