The sparkle of diamonds is a feast for the eyes 💎

Diamonds are a unique type of in-game currency. You can use them to buy boosters, increase your level reward (see What's the difference between Standard, Grand, and Epic levels?), and get extra cards on levels.

Ways to increase your supply of diamonds:
💎 Play Fishdom Solitaire levels and you're guaranteed to get diamonds for completing them.
💎 Collect streaks of cards. The longer they are, the more diamonds you get per level.
💎 Complete levels without using all the cards in the deck to get a bonus diamond reward.
💎 Play the game more often—you can get lots of diamonds every hour you're in the game!
💎 Collect stars in aquariums—each will give you some diamonds.
💎 Connect to Facebook and/or subscribe to the game newsletter. You'll receive several diamonds for either of these actions.
💎 You'll definitely earn diamonds if you feed your fish and keep their aquariums clean.
💎 Achievements in events and competitions will sometimes give you diamonds in treasure chests.
💎 You can buy diamonds in the in-game store.

Enjoy the game and let it rain diamonds! 😉
