Description
Cross Fold is a folding puzzle, inspired by Bob Hearn's Rectangle Unfold (a.k.a. 4!-fold, pronounced "fourfold"). The challenge of the puzzle is to fold the square grid pattern around a cubic "U" shape, made of five cubies. The secret of Cross Fold is that half of the puzzle is folded inside-out using the gap in the U shape to cross over.
