Tilt Maze

게임 설명

The Brio wooden labyrinth in a browser tab, and the rare page here that is better on a phone than on a desktop: you tilt the actual phone. The ball is a solid steel sphere rolling without slipping, so it accelerates at (5/7)g·sin θ rather than g·sin θ — two sevenths of gravity goes into spin, and that factor is the difference between a ball and a cursor. Rolling resistance, a restitution measured for steel on wood, and a 60 Hz sim split into substeps short enough that a fast ball can never cross a 6 mm wall without hitting it. On iOS the motion permission is asked from the Start button, beta and gamma are rotated by the screen angle so landscape does not tip the board sideways, and a Re-zero button means you never have to hold the phone flat. No sensor: the mouse or the arrow keys tilt the same board, to the same limits. Five boards, one clock, and every board proved before you see it — a flood fill on the ball's centre finds a route with 3 mm of clearance either side, and any hole that would sever the last one is never placed.
