Flood Fill 2

Details

Flood Fill is a great puzzle game with a colorful and a fresh design. The game rule is quite simple. Color the shapes within four color so that neighbors don't have the same color. Using 4 colours to fill the picture and don't let the colours touch together. In this game the goal is to fill in the pieces with at most 4 colors. Two pieces that touch can’t share the same color. The game is mathematically interesting since the Four Color Theorem says that for any such ‘map’, four colors is enough.
