A puzzle skill game where you have to flood-fill an area of blocks with a replacement color to connect three or more same colored blocks.
Click with your mouse to select a starting block. After that all same colored blocks which are connected to the starting block will be flooded by the replacement color.
To get points there must be at least one block outside of the flooding area which has the same color as the flooded area. More blocks flooded – more points you get!
As you progress, the game is getting more and more complex with more different colors and less time to click on a target block.
There are also several powerups (for more details about them read in-game help).
The game is over either if the time for clicking on a starting block is elapsed or if the total flooded area consists less than three same colored blocks.
