Time for a brain-bending challenge. Otrio, the head-to-head strategy game, is perfect for playful competition. To win, you must place three circles of the same color next to each other. The adjacent circles must either be the same size or progressively larger or smaller. Concentric circle placement on a single space is also allowed. The rules are simple, but the game is complex. Depending on the cleverness of your opponent, you may need to sharpen your strategic skills and practice critical thinking. Otrio comes straight from the Brain Workshop. It's a unique game—entertaining, challenging, and visually appealing. The fascinating game board is made of solid wood, providing an elegant gaming experience.
