The Watchtower
Level 16 opens with a long, quiet walk: your gnomes start all the way on the left, on a solid rocky floor that runs straight to the wall. But the calm does not last — the road leads to the watchtower, a tall pillar of rock with a secret hidden inside.
Halfway there lies a small pond. It looks harmless, but a gnome that walks in head-first will not walk out again. One well-built stairway is enough to carry everyone safely across.
Then comes the real puzzle. The finish is carved into a cave at the foot of the watchtower, cut off from the path on every side. This level asks for two tools at once:
- The builder stacks a stairway against the rock, step by step, to reach the top of the tower.
- The diagonal digger (↘) tunnels down through the stone at a slant, straight towards the hidden cave.
Time it well and the tunnel opens right at the cave. Dig too deep or too far, and your gnomes drop out of the tower into nothing. Keep an eye on the clock — good luck!
