The Great Mountain
Level 15 is one big mountain. Your gnomes start high on the top right, and the finish waits deep inside a cave at the bottom left.
Straight down will not get you there — the cave sits far to the left. This is where the new diagonal diggers shine: send gnomes digging down-left and down-right to carve a sloping tunnel through the rock.
Combine vertical diggers with diagonal ones to steer the tunnel toward the cave. Watch out for the water pools along the way — one wrong step and a gnome is gone.
Saved enough gnomes? Then a brand new challenge awaits you next week.
