How to use
Choose a challenge from the puzzle booklet or guide and place the starting pieces as indicated. Study the goal configuration and plan a sequence of moves to assemble the tower or trigger the lock mechanism. Move pieces one at a time, checking how each placement affects the overall structure until the objective is reached. For best results, attempt easier puzzles first to learn how the pieces interact, then progress to more complex configurations. The game is intended for solo play but can be used collaboratively to discuss strategies and solution steps.
Usage recommendations
Use on a flat, stable surface to ensure accurate stacking and to prevent pieces from shifting. Store pieces in the original box or a small container to avoid loss during travel. When used in educational settings, allow time for reflection after each attempt to discuss planning strategies and alternative solutions.
