Lonely Mole

Keep the hammer away from a column for 10 rows: a mole there waves at you.
How to find it, step by step
- Keep the hammer away from one column for 10 rows in a row.
- A mole on the far rows of that column waves at you. That counts.
Reward
Moles have a life of their own: watch them yawn, greet each other... and dance on row 777.
Tips
- Easiest on a 5 or 6 column board: park the hammer on one side for a while.
In-game hint
Moles get bored when nobody visits them.
