The pressure is on in this 3D race against time! Set the moving timer wall, pick a challenge card, then race to build the shape that will pass through the cut-out in the card. As you solve, the wall ticks towards you. If you get it right, your shape will pass through the hole in the wall. If you get it wrong, your shape will get knocked down and you'll have to try again! Includes game board with moving timer wall, seven blocks, and 53 double-sided cards (106 puzzle challenges). For ages 7+. No batteries required. Recommended age 7+ years
