Just as the name suggests, this puzzle shaped like the letter H is made of two pieces entwined together. At a glance, the pieces that make up the puzzle may appear to be of the exact same shape, but they actually differ slightly. Do you think you can disassemble the two pieces? The movement of the pieces is very tricky, so you also need to be careful that your memory does not play tricks on you. Designed by the Dutch genius Oskar The theme is entwine.
