Object: make the Robot walk the longest possible tour on the board.

Click the board to drop the Robot.
At first this Robot will face East, but you can change that.
A 'turn' button will appear at the lower right corner.
Click this button (as often as necessary) to make the Robot face North, West or South.

To play, simply click the Robot.
It will slide until the next position marked 'R','L' or 'B' (meaning go right, go left or go back)
Positions with the same color will carry the same marker.
When the Robot lands on such a position, it will turn accordingly.

If you clicked the Robot and there is no marked position in the direction the Robot is facing, the Robot dies.
In this case you have to go back to the start and drop the Robot somewhere else or turn it in to a different direction first.

Every move of the Robot is counted at the top left corner.
There the length of the longest known tour is also displayed.
Your goal is to find a route of this length.

If the Robot ends up at a position where it was before, facing the same direction as once before, then the Robot will die, and the last move will not counted.

Variants: there is also one variant with random setups.
