A unique educational strategy game played in 3D space: 【3D Four-in-a-Row】 The goal is to get four of your colored spheres in a row. Because you're thinking in 3D instead of 2D, this wooden educational toy is perfect for spatial reasoning, logical thinking, and right-brain training. The texture of the wood is beautiful and makes a great interior decoration. This is a well-made toy from Sakai Shikki Sangyo Co., Ltd. Age: 6 years and up 【Condition】 The plastic case has a crack (see photos). The main body and spheres are in good working condition. No missing pieces. Will sell to those who understand that this is a used item. #3DFourInARow #EducationalToy #WoodenToy #RightBrainTraining #SpatialReasoning #StrategyGame #Montessori #SakaiShikki #BoardGame #DiscontinuedToy
