Arkedo Series - 02 SWAP! is Dual-Stick Action Puzzle. The concept is easy : you just swap pairs of blocks, horizontally or vertically. And have fun. Arkedo Labs has carefully selected the best genes of the dominant "color-match" type, then crossed them with a very rare but powerful "Dual Stick" genotype. The result, after quite some trials and errors, is a very stable and combo-based hybrid, which should easily find its nest on any living room, and stay there forever.
