This Month's Prize

The prize for the May 2021 contest is a Butterfly's Revenge puzzle from Puzzle Master and a Celtic Knot puzzle from Braingle.

Butterfly's Revenge

In summer most butterflies float and flutter. This butterfly is not as cute or beautiful. It wants revenge on all who try to solve the puzzle. Can you master the butterfly and remove the handle from the middle of the butterfly? In the Celtic Knot puzzle, the objective is to place the puzzle pieces into the tray so they all fit and make a continuous loop. It's more difficult than it seems.

Next Month's Prize

The prize for the June 2021 contest is a Triad puzzle from Puzzle Master and a Celtic Knot puzzle from Braingle.


Made of sturdy and richly color-anodized metal, the Triad Puzzle will disassemble into three separate pieces. The objective is to take it apart and then reassemble it. In the Celtic Knot puzzle, the objective is to place the puzzle pieces into the tray so they all fit and make a continuous loop. It's more difficult than it seems.
