Fillblox

An engaging logic puzzle where your goal is to fill the playing field with shapes. You're given several blocks of different forms — drag each one into place so that not a single cell is left empty. Sounds simple? With every level, the board gets larger and the pieces grow more numerous and more intricate. An adaptive difficulty system adjusts to your pace — if you're blazing through levels too quickly, the game will throw a tougher challenge your way. Stuck? Use a hint to automatically place one piece in the right spot.
