The aim is to put the space invader together.

Each space invader is made up of 16 tiles.

Each tile must be moved into the yellow square.

Click on the top part of a tile, the word 'move' will appear.

A tile can then be dragged about. A tile cannot be dragged past the line of symmetry.

A red dot will appear when you move your mouse over the middle of a tile.

Click on the middle of a tile to rotate it through 90 degrees clockwise.
