What are crystals and how to earn them?

Crystals - The In-Game Currency~

At the top of the screen, you can see how many crystals you have:

Crystals are spent on upgrading your tank, whether this be new paints, turrets, hulls, protection modules, or Micro-Upgrading any of the aforementioned items.

For example, you need 180,000 crystals to buy the "Space" paint:

After you confirm a purchase, you will be charged the number of required crystals, and the selected item will appear in your Garage (provided you have a high enough crystal balance to afford the purchase).

How To Get Crystals?

1. Via battle:

a) From Gold boxes that are randomly dropped on the battlefield.

Gold Box

b) From battle funds divided at the end of any Matchmaking battles:

During holiday festivities, the Deathmatch or Solo Juggernaut modes are occasionally released, and you can gain crystals in this mode, based on the number of tanks destroyed during the battle:

c) From public PRO Battles:

During the battle, you can see the battle fund in the bottom-right corner of the screen:

NOTE: Private PRO Battles and XP BP mode do NOT give you crystals!

2. Daily Missions:

Daily Missions are three optional tasks that every tanker receives upon entering the game. The reward for completing one of these tasks is dependent on both your rank and the difficulty of the task.

Daily missions are not reset with scheduled server restarts. This means you can take as long as you need to perform a specific mission — an hour, a day, a week, or more. Though while they are not reset, they are refreshed. This means that after the server restart when you next log in, you will find a full stock of three daily missions awaiting completion. So if you only had time to finish two missions the day before, the incomplete mission will remain, and two new missions will have appeared next to it.

If for some reason you don’t like a mission or find it too hard to complete, you can exchange it for a task of a different type. You can do this once a day for free, and any number of times after that for a specific amount of crystals. The cost in crystals will depend on your rank.

3. Referral Links:

Referrals are players who you invite into the game via a link or banner.
You get crystals when your referrals rank up, as well as you get 10% of the number of crystals they buy in the game!

Please note: HTML5 Referal links are not working at the moment. Will be fixed soon.

4. Completing Challenges:

Each month, a new stars Challenge is introduced in Tanki. In these Challenges, you earn stars by playing Matchmaking battles. After obtaining a certain amount of stars, you can unlock rewards/get prizes. One of the rewards you can get is crystals.

5. Taking Part In Contests:

The Administration regularly organizes contests which you can take part in, and win some cool prizes, including crystals. You can find a complete list of active contests here.
