2v2 is a battle mode in Clash Royale where two players play against two other players. It is accessed by pressing the Party button from the main menu. It can be played with a random teammate, a Clanmate or a Friend. 2v2 battles have all the rewards of regular battles without putting Trophies at risk. 2v2 is also sometimes used as a Special Event Challenge, and they are also playable in Friendly Battles.
2v2 battles are battles between 2 teams of 2 players. All 4 players play simultaneously in 1 Arena, and each team attempts to win more Crowns than the opposing team to win the match, just like normal 1v1 battles.
2v2 battles can be played with a friend, a clanmate, or a random teammate. It can also be played in Friendly Battles with clanmates.
In 2v2, the King's Tower has 2 cannons, is wider, has 2 Kings, has a special badge with 2 Crowns on it and it has about 20% more health than an equivalent level King's Tower. Both cannons have their own individual range. The Princess Towers remain unchanged.
There are no level restrictions in normal 2v2. The level of the Crown Towers is the average of the 2 players' individual Crown Tower level, rounded down if necessary.
Both players use separate decks. Elixir generation is slowed to 85% of the normal generation (roughly 1 Elixir every 3.3 seconds). During Double Elixir and Overtime, Elixir generation is decreased to 70% of the normal Overtime generation (1 Elixir every 1.8 seconds, and 1 Elixir every 1.2 seconds in Triple Elixir).
At the beginning of the battle, players can briefly see their teammate's deck, and during the battle they can see the teammate's current cards in their hand. It is possible to work out how much Elixir the other player has by looking at the number beside their current hand of cards.
They will also see where their teammates are hovering their cards. This is very helpful in coordinating attacks and defenses, as well as designating who will respond to a situation, so cards should always be dragged onto the arena if time permits.
2v2 battles do not award or deduct Trophies from players, but they do award Chests and Victory Gold. 2v2 battles also count towards the Crown Chests.
All spells affect both players of a team. For example, a friendly Rage or Heal would enrage or heal all friendly troops within radius, including a teammate's. Similarly, an opposing Freeze or damaging spell would freeze or damage both teammates' units.
However, an Elixir Collector will only generate Elixir for whoever plays it. The opposing team's Elixir Blobs, when destroyed, only give 1 Elixir for whoever destroys it; if a Crown Tower destroys an Elixir Blob, each player is the owner of one Princess Tower and one single King's Tower (it becomes evident if two players picked different Tower Skins).
The arena space behind a King's Tower is expanded, to have more space for deploying troops. However, there is less space between the sides of the King's Towers and the edges of the Arena.
Clan Battles were a special event which started with the Clan Battle Chest.
Clan Battles were triggered by a special button on the top-right corner of the Clans screen.
They worked like 2v2 Friendly Battles in the sense that they didn't drop rewards and were at tournament standard. Clan Battles, however, were played with a member of the same Clan against two opponents from a different Clan.
Clan Battles always took place in the Royal Arena.
Winning a Clan Battle would award one Clan Battle Win to the Clan Battle Chest, no matter how many Crowns were taken.
The Clan Battle Chest was a type of chest belonging to a clan. It was similar to a Clan Chest in the sense that clanmates needed to co-operate in order to open it.
The Clan Battle Chest started every other Friday. All players in a Clan at the time had the opportunity to gather Clan Battle wins for the Clan Battle Chest.
Players were able to gather Clan Battle wins for three days. They would attempt to gather as many wins as possible in order to maximize the rewards for the Clan Battle Chest.
Once the players had enough Clan Battle wins for the maximum reward, or the three-day Clan Battle Chest event had elapsed, the Clan Battle Chest was be available for opening. The amount of Gold and cards offered do not differ between players, but its contents will differ depending on the Arena the player is in. For example, a player in Arena 7 will not be able to obtain cards from Arena 8 through the Clan Battle Chest.
The total number of wins was tallied in the Chest tab of the Clan info screen. There, players were ranked based on the number of wins the player had contributed. For this purpose, a Clan Battle win was shared between the two winning clanmates, so each win awarded both winning players with half a win each.
To earn the rewards from the Clan Battle Chest, a player must have remained in the Clan for the duration of the three days and must have contributed at least half a win to the Chest. A player that had just joined the Clan must have waited until the next Clan Battle Chest was available, regardless of any previous contributions.
If a Clan had earned the maximum reward, players could still play Clan Battles but without further rewards. Players with zero contribution were still ineligible for the Clan Battle Chest, even if they had contributed after that.
The n-th tier of a Clan Battle Chest required wins total and rewarded Gold and cards.
The mode of 2v2 was first introduced as Clan Battles. The first Clan Battle Chest event started on 24/3/17.
On the same day, a maintenance break fixed issues where the game would crash when spectating a Clan Battle.
On 3/4/17, a maintenance break increased the requirements of wins by 150%. The sizes of the Clan Battle Chests stayed unchanged.
On 12/6/17, an update expanded the 2v2 mode, adding a temporary 2v2 button adjacent to the normal Battle button, allowing players to play matches with players from outside the player's Clan, as well as the player's friends from the Friend list. This mode of play also allowed play with clanmates as it did previously, and allowed players to obtain Chests without playing 1v1 Arena matches. This feature lasted for a week, as a probationary test for 2v2.
This 2v2 mode no longer uses friendly rules; Crown Towers and Card levels are no longer adjusted to tournament standards.
This update unified the Clan Chest and the Clan Battle Chest, as both ladder matches and 2v2 matches contribute crowns to the Chest. If two players from the same clan pair up, the crowns they gain count for both players, resulting in double contribution.
On 30/6/17, the 2v2 button was made available for the entire month of July, retaining the same functionality as it did in the earlier probationary period. This allowed players to play 2v2 matches outside of Clan Battles. This button was then removed on 1/8/17.
On 21/8/17, the 2v2 mode was made available outside of Clan Battles once more, permanently this time.
On 9/10/17, the October 2017 Update added a post-battle chat in 2v2 battles as well as the ability to rematch (play another match) with the co-mate. It also allowed teaming up with clanmates or friends to play 2v2 Special Event Challenges.
On 25/4/18, the Clan Wars Update allowed players to see their teammate's current cards in hand by tapping their teammate's name. The same update also added an in-game ban from 2v2 when a player would leave their 2v2 battle.
On 5/9/18, the September 2018 Update allowed players to see their teammate's current Elixir.
On 5/12/18, the December 2018 Update added the ability to send a friend request to teammates after a 2v2 battle.
On 15/4/19, the April 2019 Update extended the duration of Overtime in 2v2 battles to 3 minutes (from 1 minute).
