These Tetris-like puzzles feature several different shapes or "noodles" composed of beads stuck together with thin connecting plastic. The puzzle boards are regions of dents in which you will configure your shapes. The object of the game is to fit all of the noodles on the Kanoodle board, (the picture for each challenge starts you out by showing you the correct placement for some of the pieces). Each setup has hundreds of possible combinations but just one solution. It can get quite frustrating when you end up with one bead off the board and one open spot, but the more you try the closer (or farther) you can get. Once you master the 2D setup, you can play 3D Kanoodle with the same key concept but one challenging twist - use all of the pieces to make a pyramid. Kanoodle has twelve 3-5 bead shapes, a rectangular shaped game area, and 101 puzzles. Kanoodle Genius is composed of seven 5-bead shapes, features an irregularly shaped play area, and offers 195 advanced puzzles. Kanoodle Extreme offers the thrilling challenge of over 300 2D and 3D and 2D sliding puzzles.
