Tower of Hanoi Sort

Tower of Hanoi Sort takes the classic disk-moving puzzle and gives each piece a color and a number. A piece can only be placed on another piece when the colors match and the number underneath is larger, so every move has to satisfy both rules. The puzzle rewards planning ahead: decide the final order of each stack before you touch anything, because a bad first move costs several steps to undo.

• Only the top piece of a stack can be moved
• Click the top piece, then click the destination stack
• A piece can only go onto the same color with a larger number
• Plan the order of moves before you start
• Sort every stack to solve the puzzle

Click a piece to pick it up, then click the tower you want to place it on.

• Work out the final order of each stack first
• Move the smallest pieces at the end
• Use an empty stack as a buffer
• Check that a move does not trap your largest piece

• Hanoi-style piece movement
