Create islands by uncovering waterways.
Each island is made of an explicit number of tiles. By clicking a yellow ground-tile it will transform into a blue water-tile and the other way round.
The goal is to separate all islands from each other and connect all waterways horizontal or vertical.
Watch out: The waterways must not been disconnected nor build an coherent square!
Hint:
Just click on the tiles to transform them. The small tiles above the playing field are showing remaining faults at islands or waterways.
