Cast Duet by Hanayama
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 the rings from the grid and return them to their original positions? After you conquer that, next, try also to fit the two rings ar the four-crossing point on the grid indicated by the numbers. The level of difficulty increases as players aim for crossings with higher numbers.
An ambitious product by Oskar packed with multiple problems to be solved.
