The rules for battles are a bit different in the new village. Chiefs go head-to-head in Versus Battles, attacking eachother's villages at the same time. The Chief who scores the most stars wins!
Some additional details:
You always attack a player who is online, and this player will in turn attack you.
Chiefs are matched mainly based on their Trophy count in the new village.
To lose a battle doesn't mean that you lose resources, you only lose Trophies. The loot that you win doesn't come from the opposing player.
In the case of both Chiefs scoring the same star amount and same destruction percentage, a Draw is called and neither player wins anything.
You don't have a chance to "Next" an opponent found for you
A skilled Chief remembers to balance his offensive capability with his defensive capability. Remember to keep developing your Builder Base's layout and defenses, as well as upgrading your troops!
Rewards & Trophy ranges
For each victorious Versus Battle a Chief gains a loot reward determined by his own Trophy range. Gaining more trophies will move you into a higher Trophy range, which will in turn yield greater loot rewards. The current loot rewards as well as the rewards of the next Trophy range can be seen by pressing the "i" icon in the Versus Battle screen.
Once a Chief gains his 3rd win, he will receive a Bonus Loot reward with this win. The "3-Win Bonus" text indicates the total amount of loot that the 3rd win will give.
Loot Reward Cooldown
After gaining 3-wins, a 22-hour timer begins before Loot Rewards for wins become available again.
Once Loot Rewards are available again a new 22-hour countdown timer starts running behind the scenes. This timer counts down even while you work on gaining the 3 wins. When this timer reaches “zero”, Loot Rewards will become available again.
If at this time you are still working to get the 3-wins, once you do get them you will immediately be able to get Loot for 3 more wins. However, you can only "stack" two 3-win runs for loot, after which you will need to wait 22-hours.
