Crystals are the in-game currency, which is used for purchasing items (hulls, turrets and paints) and upgrading them.
There are several ways to get crystals:
1. In battle:
By collecting the “1000 crystals” boxes that can fall any time the battle fund increases by 1 crystal. These are called “Gold Boxes”.
2. By Fighting in a battle until its end.
The crystals in the battle fund are distributed according to the number of points each player scores during the battle.
You can always see the current battle fund of a battle in the bottom right corner of the screen.
3. In daily bonuses.
4. Another way to earn crystals is referrals. You can find more information about it here.
5. You can get crystals by taking part in contests. You can learn more about contests in the forum.
6. Crystals can be bought. Just click on Buy at the top of your screen when you are in the game to get more information about it.
When buying crystals for the first time, regardless of the amount purchased, you will get a bonus of 1,000 crystals for free!
