What is inside
Every ball, wall and collision is simulated. No scripted solutions, no two runs alike.
Each chapter introduces one new rule and gives you 25 levels to master it.
Sliding walls, exits that jump to another wall, ceiling hatches that open and close, breakable glass and heavy iron.
No target, no level number — just how long you can keep the box under control.
Go back to any level you have reached and beat your own record on it.
Two arenas at once: solo coordination with a single tap, or two players on one phone.
