Background
This is my flash version of the classic puzzle Pentominoes where you rearrange pentomino shapes (meaning a shape composed of 5 adjacent squares) into a given space. The pentominoes can fit into a square shape with four squares missing in any place among other things and are believed to be the inspiration behind the classic game Tetris. See how fast you can complete the puzzle to stand a chance of being entered into the high scores board.
