Foxmind Brain Builder Series Equilibrio Game Kids 5y+ In Equilibrio, players are challenged to create upright, 3-D structures with the blocks. The book depicts simple two-dimensional illustrations of the structure, and it's up to the player to determine the correct placement of the blocks and ensure that their structure can stand independently. 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. Part of FoxMind's award-winning Brain Builder Series! Increases dexterity and reasoning abilities!
