About this app
Rock paper scissors, with a twist that wakes up your brain.
A hand appears with an order: WIN, LOSE or DRAW. Just answer fast. Sounds easy, until your hand insists on winning when it's told to lose. RPS Brain turns this classic "delayed janken" game into 10 quick brain games.
Today's 3 games (90 seconds)
Everyone gets the same 3 games each day, easiest first, 30 seconds each. Finish them to earn your janken rank, from Kyu 10 up to Dan 10, and keep your daily streak going.
10 games, all rock paper scissors
Beat it, lose to it or mixed orders; two hands with a different order for each; look away; memory janken, where you remember the hands and beat them in order; trick janken, where the picture and the word disagree; counting the wins; and an advanced version with five hands.
Feels great to play
Every round starts with "Rock, paper, GO!". Each correct answer rings a note higher, and 10 in a row sets off FEVER for double points.
vs CPU and 2 players
Six opponents, each with a habit: one loves rock, one copies you, one plays what would have beaten you. Read them and win. Or sit face to face with a friend and race to answer first on one phone.
Host mode
Show it on a TV or tablet with big hands and big orders, read aloud. Great for classrooms, family gatherings and group activities. No ads in this mode.
Easy to read
Large text, bold colors, and every hand has its own shape and color.
