-The Stage 3 mine is great and can be created after you have built a Stage 2 Breeder house. Send a group of flying soldiers at an enemy house, then place the large mine next to that same house. Right before the first soldier gets to the house, drop a sheep on top of the mine. This will kill twenty of the Hairies inside and clear the way for your Baldies to take it over.

-A fast way to kill an enemy house is with your grenade soldiers. After you have built a Stage 2 Barracks, put a shield over the target house, then place a rock in front of the house to prevent the soldiers from entering. All of your soldiers outside of the house will barrage the house with grenades.
