Tumbleos takes traditional dominos to new heights! Spin the spinner to determine whether you’ll add to or subtract from the stack, then search your stash to find a block that works. Stack all your blocks first and you win, but watch out . . . your opponent might spin “tumble the tower,” and you''ll have to start all over again! This stack-’em-up game practices color matching, and counting and develops fine motor skills, social skills, and good sportsmanship. It’s the perfect introduction to game play!
