Cramped? Open it full screen.
Tiles slide onto the board from the left and the right. Each one keeps coming faster than the last.
Once a tile settles, nothing on screen tells you which side it came from. That part is on you.
Swipe every tile back out the way it came in. Race the clock, or see how long your lives last.
Every run doubles as a challenge. Share your run's link and friends get exactly one try to beat it - same tiles, same order, no rehearsing.
The server replays every submitted run swipe by swipe and only keeps scores it can reproduce. Faked numbers never make the board.
Nothing to sign up for and nothing tracking you - a random device id is all the leaderboard ever knows. Here's the whole privacy story.
