Two worlds occupy the same screen. Walls appear in one at a time — you need to be in the other.
👆 Tap to swap worldsThe screen is split into a purple world (top) and a teal world (bottom). Walls approach from the right and block one world at a time. Tap to teleport your dot to the other world before the wall arrives. Miss the switch and it's over.
The screen is permanently divided into two worlds — a purple universe above and a teal void below. Walls scroll in from the right, each one blocking a single world. Your only move is one tap to swap sides. Stay in the wrong world when the wall arrives and it's instant death. Free to play in any browser, no download needed.
Watch for incoming walls and identify which world they occupy. Tap to teleport your dot to the opposite world before the wall crosses your position. Early on walls are slow and spaced apart — at higher scores they come faster and sometimes in rapid succession, demanding quick back-to-back swaps.
Look ahead, not at your dot — you need two seconds of lead time to react. When two walls arrive close together in opposite worlds, you swap once for each. When two walls arrive in the SAME world, stay put and let both pass. The left edge indicator shows which world you're currently in.
