Gameplay

Gameplay in Clash Royale. A player has just destroyed another player's tower.

Clash Royale ranks players according to level and arena. The maximum level is thirteen, while there are ten arenas (including the Training Camp) in total in the game. A player wins by destroying more towers than the opponent, or by destroying the opponent's "King's Tower", which grants an automatic three "crown" victory. At the start of each game, each player is given a "hand" of four cards from a "deck" of eight cards selected by the player. Cards must be played in order to attack and defend. To play the cards, the player must have "elixir", which replenishes over time. Once a card is placed, a new card from the deck is added to the hand. Players unlock different arenas by acquiring a certain number of "trophies", trophies are acquired by winning battles. However, trophies can also be deducted by losing battles. Players may increase their "level" by "donating" or "upgrading" cards. A level increase also increases tower hit points and damage. The amount of experience points necessary to rank up increases with each level.^{[citation needed]}

As a freemium game, Clash Royale offers players the ability to purchase "gems" and "gold" in the play shop using real-world money. These items are used to purchase chests and cards. When a player wins a multiplayer battle, he or she may obtain a "chest", which takes a certain amount of time to open depending on the chest. Chests take a certain amount of time to unlock: Silver Chests take 3 hours to unlock, Gold Chests take 8 hours, Giant Chests take 12 hours, Magical Chests take 12 hours, and Super Magical Chests take 24 hours. Gems may be used to speed up unlocking. Chests contain cards, gold, and gems. Different levels of chest contain different numbers or types of cards. When the player has a certain number of a troop's cards, they can upgrade it to boost its "damage" and health points, among other statistics. A player can hold a maximum of 4 chests at one time; to open up chest slots a chest will need to be opened.^[6] Free chests are also given to the player once every 4 hours. Once every day, the player also has the chance to win 10 "crowns" from victories to earn the Crown Chest. Both the Free and Crown Chests unlock instantly.^{[citation needed]}

Once victorious in all of those battles they advance to arena 1 "Goblin Stadium". At 400 trophies they progress to arena 2 "Bone Pit", 800 for arena three "Barbarian Bowl". Arena 4 "Pekka's Playhouse" takes 1100 trophies to get their while arena 5 "Spell Valley" needs 1400. The next arena, arena 6 "Builders workshop" takes 1700 trophies. Arena 7 "Royal Arena" requires 2000. Arena 8 "Frozen Peak" require 2300 and "Legendary arena" take 3000 trophies respectively.^{[citation needed]}

Players may also form clans. Clan members may engage in "friendly battles" with one another, the outcome of which does not affect trophies or chests. The "friendly battle" feature allows for live spectating from other clanmates, and is used for tournaments. Clan members may also donate or request cards from one another, which provides some experience and gold when done.^[
