One of the best and lightest brain training game ever for iOS You are using 10% of your brain ability. Let’s play Brain Flash Games and activate your mind power with our 6 stunning mini games: ◆ R-P-S (Rock-paper-scissors) Rock beats Scissors, Paper beats Rocks, Scissors beat Paper. The classic mind game comes back with a new rule: you have to WIN when you see the GREEN but you have to LOSE when you see the RED. ◆ PAIR That would be great if you find someone like you. In this speed game, you have to tap 2 CARDS with the SAME character or shape as fast as possible. Don’t think it’s easy, your brain will work 200%. ◆ TRUE COLOR When you see a red CIRCLE, it’s easily to say its COLOR. But if we trick you with a yellow LABEL on the circle, the game will become chaos. You will be confused and wonder why it’s so hard to tap a red circle with label “red”. ◆ ALL OR NOTHING If you see an orange rocket, just tap an orange rocket. Is it a simple game, right? Oh wait, but if you don’t see any orange rocket, you have to tap a blue UFO, which have both different color and shape. OMG, this game is now so crazy! ◆ ONE DIRECTION If you see a shoal of blue fish move to the left, swipe left. If you see a shoal of red fish move up, just swipe down. It’s maybe the easiest game of 6. ◆ THINK DIFFERENT This game is inspired by Apple and Steve Jobs. Just tap the unique fish or jellyfish which has different color and skin pattern to get score. We have taught you all the rules. Are you ready to boost your brain and beats yourself and hackers around the world?
