Consider that the 2×2 is a pretty doable puzzle? But what if you join 2 of them together? Or 3? Or even 4? Double, Triple…
Set of 3 metal puzzles
There are three anodised aluminium puzzles in the interlocking series from Zoyo in China. Each puzzle is in it’s own nicely presented in a clear lid metal tin with a solution inside. The puzzles sit inside the tin in a cut out rubber surround to prevent scratching. Really lovely to give as a gift.
You can buy them individually but they’re really good value to buy as a set of 3 with discount.
