Object: Entrap the robots without being hit by their lasers.

Click the board to let the system randomize the setup.
Twelve crystals will be dropped along with many walls (coloured squares) and a group of pretty stupid robots (sad faces) with lasers.

The laser rays permanently radiate from each of the robots in all four directions.
The rays are blocked by the walls and the crystals.
The robots make one step at a time into any of the four main directions.
If a robot cannot move, it will die (showing a black face with white lips and eyes).
A dead robot does not move or emit laser rays.
You win when you all robots are out of order.

Click an empty position to drop your man (the yin/yang sign).
You can now make your first step by moving your man or by clicking the target position.
You can slide over empty positions along the four main directions as far as you wish.
You cannot step into a laser ray or go across it.
You lose if your are hit by a laser ray.

You can shift a wall if the space behind it is empty.
First move close to a wall, then click the target position.
You can shift a single wall piece as far as there is empty space behind it.
After your move each robot moves one step.

The Crystal Powers
To collect a crystal, first move next to it, then move onto the crystal's position.
Collected cystals are displayed at the right border.
Any crystal you collect gives you the power to bash through a wall.
You bash through a wall by first moving close to a wall, then onto the wall position.
The position behind the wall must not be empty.
The bashing move will destroy the (up to three) neighboring pieces around your man.
