Put a shelf on the left of one level and the right of the next, all the way up, so a ball rolls across each shelf and drops through the open side onto the shelf below.
What you will need
- 21 square tiles
Step by step
1. Lay the base
Put two squares flat, side by side, for the floor the ball rolls out of.
2. Raise the tower
Stand the back and side walls up, four levels high, leaving the front open so you can watch the ball.
3. Add the drop shelves
Lay one shelf on the right, the next on the left, then the right again, so each catch is under the gap above it.
