Age: 3+ Main material: wood Number of rings: 10 Ring size: Approx. 7cm to 2.8cm Base size: approx. 22 x 12 x 7.8 cm This is the "Tower of Hanoi" puzzle, which is also found in mathematics textbooks, in which 10 rings of various sizes are stacked in a cone shape and must be moved one by one to another. Follow the simple rules and use the three poles effectively to transfer all the rings to another pole to win. The difficulty level can be adjusted by reducing the number of rings, making it enjoyable for a wide range of ages, from children to the elderly. Even if your child accidentally puts the ring in their mouth, it is safe and secure as it is made with harmless water-based paint. This simple yet profound puzzle helps stimulate the brain by cultivating reasoning skills, concentration and logical reasoning. 【rule】 1. You can only move one card at a time (hand). 2. A ring cannot be placed on top of another ring that is larger than it. 3. The ring cannot be placed anywhere other than on the pillar. 【specification】 ・Ages 3 and up ・Main material: wood ・Number of rings: 10 ・Ring size: Approx. 7cm to 2.8cm ・Paint used: Water-based type ・Base size: Approx. 22 x 12 x 7.8 cm ・Weight: Approx. 380g Set contents: 1 stand, 10 rings (different sizes) *Japanese instructions are not included.
