Box & Balls, a rolling, bouncing, banking, stacking, nesting game, includes a set of eight sturdy wooden nesting boxes and eight bouncy balls. Players set up the boxes and attempt to complete a variety of challenges. For example, players can set up the boxes flat side up in descending size and deem the smallest box as the target. This challenge requires bouncing the ball across each of the boxes before landing the target. Or how about a series of boxes flat side down interrupted by an open target box? Or a "bounce box" obstacle course? The deceptively simple games require (and develop) hand-eye coordination, motor planning, and a steady hand - not to mention concentration and persistence. Clever, challenging and great fun.
