Clash Royale

Clash Royale is a real-time strategy video game developed and published by Supercell. The game combines elements from collectible card games, tower defense, and multiplayer online battle arena. The game was released globally on March 2, 2016. Clash Royale reached $1 billion in revenue in less than a year on the market. In three years, Clash Royale made $2.5 billion in revenue according to market intelligence company Sensor Tower. It is the first spinoff of Clash of Clans.

Premise
Clash Royale is a tower rush video game which puts players in games featuring two or four players (1v1 or 2v2) in which the objective is to destroy more towers than their opponent(s), with each destroyed tower being represented as a "crown". Destruction of the opponent's "King's Tower" results in an instantaneous "three-crown" victory. Matches last three minutes, and if both of the players/teams have an equal number of crowns (or none at all) at that point, the match continues into a two-minute overtime period. Here, the player who destroys an opposing tower wins instantaneously. If no towers are destroyed during overtime, there is a tiebreaker, where the tower with the lowest health is destroyed. If two towers have the same health, there is a draw. In rare instances, if the King's Tower is destroyed at the same time by both players, this also results in a draw.

In Clash Royale, players are ranked by their number of trophies which are won or lost through multiplayer battles. Players level up their accounts and King Towers by gaining Experience points through donating and upgrading cards. King Tower levels can reach level 15, and player levels can reach level 70; these factor into the competitive match-making system.

There are twenty-three playing arenas in total (excluding the Training Camp tutorial area): Goblin Stadium, Bone Pit, Barbarian Bowl, Spell Valley, Builder's Workshop, P.E.K.K.A's Playhouse, Royal Arena, Frozen Peak, Jungle Arena, Hog Mountain, Electro Valley, Spooky Town, Rascal's Hideout, Serenity Peak, Miner's Mine, Executioner's Kitchen, Royal Crypt, Silent Sanctuary, Dragon Spa, Boot Camp, Clash Fest, PANCAKES!, and Legendary Arena. Each arena corresponds to a certain trophy range.

The original Legendary Arena represented the final arena following Serenity Peak, and it consisted of "Leagues", which were added to the game in March 2017. In the League system, players played through nine different leagues above 5000 trophies ranging from Challenger I to Ultimate Champion. At the end of each season, the player was reset to half of the trophies they gained above 5000 trophies. In the October 2022 update, this reset system was done away with in favor of a longer trophy road with more arenas, as well as a separate competitive gameplay mode (called Path of Legends) that would follow a similar model as the Legendary Arena.

In June 2024, a new game mode introduced the Goblin Queen, replacing the central King Tower. As goblin-themed cards are played, the Queen's ability charges up, culminating with the release of several Goblin Babies across the opponent's side of the map. Progression in this game mode follows a similar trophy climb as the primary game mode.

Cards
Playable troops, buildings, and spells are represented as cards. Many cards are directly based on troops and buildings from Supercell's previous game Clash of Clans, such as Giants and Cannons, and the game uses a similar art style. Prior to each battle, players construct a deck of eight cards which they use to attack and defend against their opponent's cards. At the start of each battle, both players begin with four randomly chosen cards from their deck of eight. Each card costs a certain amount of elixir to play. In standard gameplay, players start the battle with five elixir points, and one elixir point is replenished every 2.8 seconds to a maximum of ten elixir points. Once a card is played, a new card is automatically drawn. Increased elixir regeneration such as Double Elixir, Triple Elixir, or Infinite Elixir may be featured in certain game modes, and the former is also utilized in the final minute and overtime of normal battles.

Clash Royale first launched with 42 cards, consisting of 14 cards for each of three levels of rarity: Common, Rare, and Epic. The February 2016 update added two new cards under a new rarity level: Legendary. In October 2021, a new Champion card rarity was added to the game, with three new cards being added. These cards differentiate from other cards as a player can only have one Champion in their deck, and each Champion has a special ability that can be activated by spending additional elixir (for example, the Golden Knight's Dash ability costs 1 additional elixir). Subsequent updates have added cards to all the aforementioned rarity levels. , there are a total of 114 cards in the game.

All cards cap at level 15 with Common cards starting at level 1, Rare cards starting at level 3, Epic cards starting at level 6, Legendary cards starting at level 9, and Champion cards starting at level 11. All cards and crown tower levels are level 11 for all tournaments, except private tournaments, where card and crown towers are capped at a certain level.

The December 2018 update added Star Points to unlock special golden cosmetics for Max Level cards. In the October 2021 update, this was changed to be available from Level 7. Players also receive Star Points when gaining experience, which can be used to give their cards an updated visual skin, usually gold in color. There are up to three Star Levels for each card, which are unlocked when the card is leveled up to level 7 (for Star Level 1), level 10 (for Star Level 2) and level 13 (for Star Level 3).

In the March 2022 update, Card Masteries were launched, which provided rewards for reaching specific milestones with cards in competitive matches. Statistics range from damage done, to troops destroyed, to towers tapped. Badges display a player's progress, and badges could be gained for other milestones as well such as wins in different game modes.

In the June 2023 update, Card Evolutions and Elite Levels were launched. Card Evolutions added a new cyclical ability: once a card is played its respective number of times to complete a cycle, the evolved version of the card can be played, consisting of more powerful stats or mechanisms. After this card is played, the cycle resets. In addition, Elite Levels added level 15 to the game. This upgrade is not tied to gold; instead, 50,000 Elite Wild Cards are required to upgrade a single card from level 14 to 15, and these are accumulated by collecting excess copies of level 14 cards.

In the December 2023 update, Tower Troops were announced. These allow for differences in strategy regarding the two smaller towers defending the primary King Tower. Previously, these were guarded by a princess archer archetype; this was converted to the Tower Princess, the first Tower Troop. New Tower Troops were periodically released starting with the January 2024 season.

Clans
Players can join or form clans with other players. Joining or forming a clan enables the player to engage in friendly battles and clan wars. It also unlocks the feature of requesting and donating cards when a player is experience level 3. Clan trading with the use of trade tokens unlocks when a player reaches level 8. There are four different types of trade tokens: Common, Rare, Epic and Legendary, corresponding to those card levels. Trade tokens can be obtained by gaining trophies, through challenges, and from the in-game shop. Each can be used to trade a certain amount of cards with other players, depending on the rarity of the trade token.

Clan Wars I
On April 25, 2018, Clan Wars were added. Initially, a given war would be separated into two days: "Collection Day" and "War Day." Collection Day saw players battling in a variety of game modes which would rotate every month. Winning awarded cards to add to the Clan collection. If a minimum of ten players played one battle each, the Clan could progress to War Day, where a Clan was matched with four other Clans with a similar number of participants and Clan Trophies. Each participant would build a battle deck using only the cards unlocked on Collection Day. After the battles, each clan was ranked from 1st to 5th based on the number of Crowns awarded by wins. At the end of the War Day, all participating players received a War Bounty containing Gold or other items. Based on their war rank, Clans would then gain or lose a certain number of Trophies. Clans would progress through Clan Leagues by gaining Clan Trophies, with higher leagues granting better rewards. Clan Seasons lasted two weeks, and at the end of each season, a chest is awarded to every participating player based on the highest war rank and league the Clan had reached during the season.

Clan Wars II
On August 31, 2020, Clan Wars II was added as a reworked version of its predecessor. Each week consists of three "Training Days" and four "Battle Days." During Training Days, participants can add troops to their respective Clan Boat, which mark the progress in the week's war and add movement bonuses based on surviving troops. Battles are fought with 32 total cards from the player's collection being used to make four unique war-decks with no overlapping cards. War-decks can be play-tested during these Training Days, though enemy Boats cannot be attacked until Battle Days. On Battle Days, players have the option of several battle variations, with medals awarded based on wins and participation. Like the original Clan Wars, Clan Trophies are still awarded for the clan's placement in the War, determined by which Clan Boat makes it the farthest in the River Race. After a week, the cycle will reset to Training Days, and each total War lasts five weeks, while each clan loses or gains trophies each week depending on where they finished that week. On the fifth week, the clan's boat stops at the Colosseum as the final round of battles before a new cycle begins against a new set of rival Clans.

Writing for Geek.com, James Plafke criticized "Clash Royale for being genuinely fun—more so than Clash of Clans—while the developer chronically interrupts the player from enjoying it." Clash Royale has received a positive response from its players, with an average score of 4.3 out of 5 on the Google Play Store and an average score of 4.6 out of 5 on the Apple App Store.
