Three jobs. Eight minutes.

The robot driving through a blue passage in the maze

Explore

An unknown maze, with no remote control. Your program has to read its sensors and find a way through swamps, holes, obstacles and curved walls, all before the clock runs out.

The robot passing a cognitive target on a wall

Identify

Victims and cognitive targets wait on the walls, and fakes are hiding among them. Read the symbols, add up the rings and report only what is real.

Learn to read wall tokens →

Map

Turn everything the robot saw into a matrix of walls, floors and tokens. A perfect map multiplies your whole score by 2.2.
