The crates are the reward, sent to you by the tournament to help you progress. The crates contain coins, gems and warrior DNA, which you will need to train your warriors. Sometimes, they contain new warriors. There are different types of them:
- Free crate: You will get this crate for free every four hours.
- Tower crate: You can order this crate once you take down 10 towers in total, one time every 24 hours.
- Random crates: Awarded every time you win a battle.
