Instructions & Controls:

This is a puzzle based on Erich Friedman's Square Puzzle. Fill the grid with squares according the numbers below and at the right. Turn all lights green to complete the puzzle, 7 levels. The original puzzle sets harder game rules. Erich says that squares must do not touch or overlap, even at the corners. This makes it much more difficult because each puzzle has a unique solution !
