	Various Google Play Achievemen...

Use the "Imp" menu near the top of the screen then drag your finger across your imps to slap them. This will increase their production for about thirty minutes.

Reclaim quarries and gold mines at the edges of your dungeon as soon as possible and set up defenses around them. Upgrade mines and quarries whenever possible to make sure your stone and gold supply is steady.

Refill empty spaces with soft dirt by tapping and holding on an empty space. Use this to create bottlenecks for your enemies.
