Puzzle Details
An amazing Square-1 mod. It needs different solution algorithms as a usual Square-1, because the top/bottom layer pieces do not follow the typical small/big/small/big sequence, but are ordered in small/big/big/small. So some solution sequences won't work. The puzzle itself is - as usual for Anthony's works - of extraordinary quality. Piece shapes are perfect, the overall puzzle functionality is great. Colours are chosen with style.
