Building Your Snowman? It's No Problem... Just A Snow Problem! There are few things more satisfying after a heavy snowfall than building a snowman! However, rolling your snowballs into position is easier said than done, especially if you need obstacles to stop your snowballs from rolling away completely! Select a challenge and place your snowmen parts and trees, as indicated, on the board. The aim is to stack the snowballs and build your snowmen. Snowballs can move horizontally and vertically across the board, but only if there is an obstacle somewhere along the same path to stop the snowballs rolling off the edge. Ages 8+
