It takes as much coordination to sing a duet as it does to solve the Hanayama Cast Duet puzzle. 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 crssings with higher numbers.
The magnetism-themed Hanayama Cast Duet is sure to be loved by any puzzle fan, with its different challenges and levels of difficulty. But be warned: at a brain-wracking 5/6 difficulty, Hanayama Cast Duet is not going to be easy.
