LEGO Puzzles My set of LEGO Pentominoes was just the beginning. This page exhibits more brain-teasing mechanical puzzles all built out of LEGO bricks. Most of the puzzles were inspired by classic puzzles that have been available in the past, but I had never seen them built out of LEGO pieces. So, if you are intrigued by such things, read on (and if you would like me to build a particular puzzle for you, rest assured that while they are not cheap, they are considerably less expensive than, say, a White Rabbit Mosaic . I will add more puzzles to this page as I create them. Checkered Pentominoes Another version of the basic Pentominoes, this set is checkered; the pieces are built of alternating cubes of black and white. Since there are 12 pentominoes each consisting of 5 squares, a total of 60 squares are occupied. I constructed a blue edged tray of dimension 8-by-8 squares (not 8x8 LEGO studs - each 'square' is a 2x2 LEGO stud size), and in the middle of the tray I built a 2x2 square to fill in the remaining 4 squares (since an 8x8 tray is 64 squares, four more than the pentominoes will fill). The task, of course, is to place all of the pentominoes into the tray. Furthermore, when completed, a perfect checkboard pattern should result.
