This 4x4x4 interlocking cube puzzle was designed when I was on holiday on the beautiful island of Anglesey in Wales. It consists of six different pieces, two of which are rather angular C-shaped pieces, which led me to give this puzzle its rather cryptic name.
This is a very tricky puzzle and the first step is work out how to link the two Cs and get them in the right position to solve the rest of the cube. Jos Bergmans, one of the top designers of interlocking cubes, said "It took me ages to figure out how to fit the two loops together. Very nice design, my compliments."
