About GAP
GAP throws walls at you with a hole cut in them: a tall slot, a low wide slot or a square window. Swipe up to stand tall, swipe sideways to lie wide, tap to be a square, and match the hole before the wall hits. Each level is ten walls, faster every level.
How to play
Swipe up for tall, sideways for wide, tap for square. Keyboard: the arrow keys.
GAP runs in any modern browser on iPhone, Android, tablets and computers. Tap Play and you are in: no app store and no sign-up. Hold your phone upright and play with one thumb. Your best score goes on the worldwide leaderboard, and on a phone you can add the game to your home screen.
