The game becomes really intense as you reach the upper levels. Cliko is part of the Architecto line, which consists of 4 exquisite games of spatial visualization. In these games, players progress at their own rhythm, as puzzles gradually become more challenging. All games include the same set of Geoblocks and a spiral book with 6 color-coded levels of difficulty.
