This digital card game comes from the creators of League of Legends and features characters from the same fantasy world of Runeterra. Players collect and build decks for online play with a strategy system that resembles classic collectible card games like Magic the Gathering and Yu-Gi-Oh.
Unlike those traditional card games, players don't need to spend money to start building their deck in Legends of Runeterra, and the game is regularly balanced to make sure every card is fair in competitive play. If you choose, you can spend money to unlock specific cards. The rate of unlocking new cards for free is also fairly quick compared to other digital card games.
Other great collectible card games worth checking out on mobile include Hearthstone, Yu-Gi-Oh Master Duel, and Magic: The Gathering Arena.
