Rules

• Each car is a dot on a grid intersection. Drivers move one after the other.
• Momentum: every move first repeats your previous move, then you may add or subtract one single square in any of the 8 directions — or nothing at all.
• So if you are travelling 4 squares to the right, you will move at least 3. Brake before the corner and plan two or three moves ahead.
• Leave the track and you are out. The line drawn between two dots must never touch an edge.
• Two cars can never sit on the same intersection at the same time, but you may drive through a dot the other car has already left.
• First car back across the start line after a full lap wins.

Expert mode

In ASSISTED mode the game shows you where your momentum lands you and which moves stay on the track. In EXPERT mode nothing is drawn: you must read the grid yourself, and you are allowed to play a move that throws you straight off the circuit — one careless move and the race is over.

Controls

Tap one of the arrows around your car, or use the 9-cell input pad. On a computer: arrow keys, numpad 1–9, space to hold your line, Z to undo. Scroll or pinch to zoom.
