This is the classic labyrinth game, made by Brio, purveyors of handmade wooden toys for 123 years, that provides players with three levels of difficulty to test dexterity. The two knobs that control the board's pitch and lateral movement are precisely calibrated to provide fine control over the tilt of the board as you attempt to guide a steel ball through a maze--marked with a hand-painted path--while avoiding numbered holes; when a marble falls through a hole, the base's sloped floor rolls the ball into a corner and out to a tray. Three boards have different mazes; the basic-level board has eight holes, the mid-level has 21 holes, and the advanced has 60 holes. Crafted from durable beech, hand-sanded, and painted in non-toxic high-gloss red lacquer that resists chipping, the four sides of the labyrinth dovetail precisely at 90º for a seamless fit. Includes two steel balls. Ages 6 and up. 11 1/2" L x 12 1/2" W x 5" H. (5 lbs.)
