Take the parts apart and put them back to their original shape, that is the objective of this great metal puzzle. A word from the designer: At first glance, it looks as if there is only one ring hanging from the grid but there are in fact two rings attached with a magnetic force. Can you separate them from the grid and return them to their original positions? After you conquer that, try to fit the two rings at the four-crossing points on the grid indicated by the numbers. The level of difficulty increases as players aim for crossings with higher numbers. Theme: Magnetism. An ambitious product by Oskar packed with multiple problems to be solved. Hanayama Co. 2005.
