Object: deactivate all robots without being hit by the lasers.

The robots are revolting. You have to deactivate them by collecting the crystals which control them.

Click the board to let the system randomize the setup.
Ten crystals will be dropped along with many walls (coloured squares) and ten pretty stupid robots 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 body with white eyes).
A dead robot does not move or emit laser rays.

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 you are hit by a laser ray.
You win when you have collected all jewels.
To collect a crystal, first move next to it, then move onto the crystal's position.
For each jewel collected, one of the robots will die.

You can also 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.

In rare cases a jewel might be enclosed in walls and therefor not immediately accessible by your man. For this case you carry one load of explosives with you.
You trigger the explosive by first moving close to a wall, then onto the wall position.
The position behind the wall must not be empty.
The 'explosion move' will destroy the (up to three) neighboring pieces around your man.

Variant 1-b: 15 robots active.
Variant 2-a: robots can move through walls, 10 robots.
Variant 2-b: robots can move through walls, 15 robots.

The variants are increasingly challenging; so if you are bored with one level go to the next!

Please note that there is an alternative (more colorful) piece set.
