Shape Logic is a fun game that helps develop spatial, abstract and quantitative reasoning skills. To solve the puzzle challenges, stack green pieces on top of blue pieces, or vice versa to create identical shapes. Through hands-on play, players build key skills, strategies and mathematical understandings, such as part-to-whole relationships. Shape Logic, as part of ThinkFun special collection of STEM games, encourages children to develop reasoning skills through fun, multi-level challenges.
