The rules that matter
Fight at the end of the day
Beating a player ranked above you scores more than beating one below. By the end of the day, the others have played and the ranking is tighter: there are more people above you to beat.
Pick similar power
An opponent very close to your power gives good points while staying beatable. Much weaker gives little; much stronger and you may lose.
Look after your formation
A well-built formation gives attack, defense and HP bonuses (up to +12% each). Check that your heroes trigger the full bonus before you fight.
Set your defense separately
Your attack squad is not your defense squad. If you don't set your defense, others beat you easily while you sleep.
Example: beating 1st place gives 25 points, 2nd 20, 3rd 15, 10th only 8. By the end of the day, more players sit above you: that is the time to fight.
With 70.1M power: an opponent at 60.5M gives little, one at 85M may beat you, one at 69.8M is the best choice.
Getting the most points
The daily reward has three tiers: 1, 3 and 5 challenges. Beating every opponent offered adds 5 points.
Your attack squad is used when you start a fight. Your defense squad is the one others face while you are away: set it separately and check it after every hero change.
