What is the fastest method to acquire gems in Clash Royale?

The fastest method to acquire gems in Clash Royale is through making in-app purchases, where players have the option to buy varying amounts of gems directly from the game's shop using real money. This method guarantees an immediate addition of gems to a player’s account. Gems can also be obtained for free in-game by completing achievements, opening free chests or crown chests, and through the reward system in Clan Wars, although these methods are slower compared to purchasing them directly. Regular participation and progressing in special challenges and events can also provide opportunities to earn gems more quickly than simply waiting for chests to unlock or completing daily tasks.
