5. The explorer without footprints
The explorer walks around the board from the starting point to the target, trying to visit all the boxes. As the explorer walks s/he leaves coloured footprints, which allow the robot to follow the steps by interpreting the colours. The game becomes even more intriguing when the explorer clears away the footprints leaving only the colours.
Required material: chequered board, tiles with footprint pictures, red, yellow, and grey markers (or pencils)
