Let's get these balls rolling! Tumble maze is a solo action, gravity-powered puzzle game that challenges you to roll stainless steel balls into specific spots with a minimum of trials. You must navigate between obstacles and use bonus walls to guide the balls into the right directions. This ball-rolling game uses the forces of physics and gets tougher with higher-level challenges! First, pick a challenge sheet and place it in your maze board. Then set up the walls and balls to match the challenge. The challenge is to determine where to add the indicated wall(s) to change the trajectory of the balls. Roll the balls to their targets to win! Recommended for 1 player, ages 8 and up. Made in China.
