Rebuild Square is a new puzzle game similar to the classic jigsaw puzzles. The difference consist in the fact that the puzzle of bricks colored is generated dynamically, in random mode, from the device. This allows infinite possibilities to play with puzzles always different. The aim of the puzzle is to assemble together the colored bricks in order to reconstruct the original image inside the rectangle highlighted by a white border with dark background. We have four levels of difficulty from Easy mode which only provides six colors and six bricks up to Strong mode that offers fifteen colors!
