There are lots of in-game ways to earn Crystals, including Quests, Daily Gifts, and by linking your social media.
There are even out-of-game tasks you can do to earn Crystals, like watching ads in the shop.
To buy a significant amount of Crystals, you should install and play Rush Royale through Freecash, who will pay you for your progress.
Rush Royale has an overwhelming number of currencies, but Crystals are among the most important. There are dozens of ways to grind them, including ways to earn them without spending real money.
Follow the Rush Royale Social Media Channels
The game has seven official social media channels. Joining each one via the app earns 10 Crystals per channel, up to 70 Crystals total.
Daily and weekly quests are quick to finish and often reward Gold that can be spent on Crystals. You need to earn 150 Trophies to unlock the Quests tab.
Buy the Battle Pass for Guaranteed Crystals
The Premium Battle Pass ($10.00) rewards 75 Crystals on completion. The Legendary Battle Pass ($13.50) rewards 150 Crystals.
If you want the other items in the pass, the Crystals make it better value than buying them separately.
Participate in Special Events and Tournaments
Limited-time events like Mirror Match, Elemental Battles, and seasonal festivals award Crystals for participation and strong results. PVP Rhandum League seasons follow the same pattern.
Spin the Rhandum Roulette
The Rhandum Roulette sits at the bottom of the store page. Watching three ads earns one spin, with a chance to win up to four Crystals.
Crystal generator websites are scams. There is no safe or legitimate way to add free Crystals to a Rush Royale account through third-party tools. Avoid these sites and any Telegram groups promoting them.
For a faster route to Crystals, earn gift cards through Freecash and spend them in-game. For a free route, work through the in-game methods above.
