A train full of children is on its way along some tracks and dangerous obstacles are not far off. Your job is to identify the danger ahead and use provided materials to create a safe route to the tunnel. There may be pits the train would fall into or bombs that will explode if hit by the train. You may have to create one bridge or many. Just arrange the items by flipping and sliding them into position until you have created safe bridges for the train to drive over. Then hit play to see the train attempt to make it to the tunnel. Earn points for each train car that makes it into the tunnel.
