This game is very interesting and makes your brain work hard! The objective is simple. There are 3 stems. On one of them are piled several disks in ascending size order. You have to move the disks in such a way that the pile will be rebuilt identically on one of the 2 other stems, knowing that you shall not move more than one disk at a time, and that the upper disk shall be smaller than the one below it. At the begining of the game, choose with how many disks you want to play by clicking on corresponding number (3, 4, 5, 6 ou 7). The pile will appear on the left stem. Click on the disk you intend to move and drag it to the stem you want. Once above it, release the mouse button to put the disk. Have fun!
