The Hanayama Cast Cyclone was designed by Kyoo Wong and released in 2021.
It is made up of four rings which you must try and seperate and then put back together.
At first glance the pieces all look the same but there are in fact two different kinds of piece. Made to high tolerances which restrict the amount of movement possible creating a really tricky little puzzle to solve.
It is rated as 5 out of 6 stars on the Hanayama difficulty scale.
