Cliko
Cliko is the most advanced puzzle set. This puzzle book also features 3-D challenges, but players must use two-dimensional illustrations from a "straight on" perspective to build the 3-D structure. The book features 50-60+ models to recreate; each challenge includes a simple illustration of the structure to build, a difficulty rating, and a list of blocks the player must use. Because the same set of blocks is used in every set, puzzle books are also available separately.
