You join pairs of equal figures to make them disappear, using a free way between both of them. The path cannot bend more than 2 times. You pass the level when there's no more blocks, but if you get stuck before you're lost. Also, a bad move will make you lose 10 seconds and a good one earn them. Can you complete the 6 levels of increasing difficulty?
Click on the two figures that you want to join; if an empty path exists between them, and this path has no more than 2 turns, both will disappear and in this way you empty the place.
