Inspired by Inca stonefitters who worked with unparalleled precision, your kids will follow in their tradition as they play this challenging three-dimensional strategy game! Each player receives 11 Rumis 'stones' of a single color and varying shapes. The goal is to reconstruct an Inca monument---and the player with the most stones visible from above wins. Includes four 'building plan' game boards, a turntable, wooden 'stones,' and instructions. Sharpens critical-thinking skills!
