Checkerboard – Advanced Sliding Logic Puzzle by Siebenstein-Spiele

Checkerboard is a beautifully constructed logic puzzle that challenges both spatial reasoning and pattern recognition. Designed by Siebenstein-Spiele, this striking round puzzle combines natural wood, layered construction, and an acrylic guide plate to create a deeply engaging mental workout.

Your objective is deceptively simple but extremely demanding: shift all 25 round wooden tokens so that no two tiles of the same color appear in any horizontal, vertical, or diagonal line. Once achieved, the puzzle must then be returned to its original starting configuration.

Movement is strictly controlled by precisely cut channels in the acrylic top, allowing motion only in specific directions. Each adjustment impacts multiple lines at once, requiring careful planning and logical foresight.

Why You'll Enjoy It:
