Play World Wars game. This a cool strategy game similar to dice wars. The number of units a particular territory has is the number of dice you get for battle. The battle is decided by throwing the number of dice and adding up the values. So, if you using a 3 unit army to attack a 1 unit army, you have a pretty high chance of winning the battle.

Tip: Units can only move by attacking. If you win the battle, one guy is always left behind to keep the territory. So, remember to move the big numbers forward and try not to block them in.
