Battle points are earned in Battles. Both participants in the Battle receive Battle points. The amount of Battle points depends on the Resource points lost by the enemy (lost due to lost ships and defense unit in that particular Battle).
Note that you don't receive battle points if you attack members of your own Alliance or Inactive players.
The Battle points are calculated with one of the formulas listed below, depending on whether you are the winner or loser in the Battle:
- The winner of the Battle takes Battle points equal to:
- The loser of the Battle receives Battle points equal to:
X* √ (Y-X/2)/(YX/2)
- X - Resource points lost by the winner of the Battle;
- Y - Resource points lost by the loser of the Battle;
When the Battle finishes with a draw, the same formulas are used and the player that has lost less Resource points is considered the winner (regardig the formulas only).
When you are defending a Sun during Sun Attacks - you receive three times more battle points than usual.
