Basics of Battle

Summary

 * If you win a battle, by destroying a greater amount of Crown Towers, which awards Crowns, earning Trophies and you can go up to unlock new Arenas. Arenas unlock new Cards.

Battle

 * Players square off against live competition on tiny maps dotted by six buildings; three for each player: two Arena Towers and one King's Tower, respectively.
 * The object of the battle is to destroy the other player’s King's Tower (middle building) while protecting your own.
 * You’ll do this by deploying troops from a deck of cards (drawn from a Battle Deck that you’ve built) anywhere within an allowable area on the field.
 * Each card requires a certain amount of Elixir to deploy, but your Elixir regenerates quickly, so you’re only ever moments away from deploying your next troop or spell.
 * More cards are collected by unlocking chests won in battle or bought in the shop, which in turn will unlock new cards that you can add to your Battle Deck and level up the cards you already have.
 * In the event of taking down an Arena Tower, spawn-able territory on the opponent's side is opened, available for you to deploy your Troop Cards to have an upper hand on the opponent.

Battle Deck

 * Your battle deck is the rotation of cards you wish to have in battle.
 * To change these, you must tap the card you wish to add into your battle deck and tap, 'Use', before tapping the card that you would like removed from your battle deck.
 * Next to the Battle Deck heading, it will display the average elixir cost of all your troops. Occasionally, this can come in handy when deciding if your deck is suitable. For example, a deck with an average of 3.5 elixir that is semi-powerful, is better than a deck with an average of 4.7 that is slightly more powerful, as you will not be able to deploy troops as often to counter enemy offenses and proceed with your offensive strategy.
 * The battle deck consists of a maximum of only 8 cards, so you want all your cards to be ones that you will be using, otherwise that is misuse of a valuable cardspace.

Winning

 * If you destroy the other player's King's Tower, you win immediately.
 * If no one is able to take down the King's Tower within the first 2 minutes, you and your opponent's Elixir regeneration speed is doubled.
 * If no one is able to take down the King's Tower, or each person has an equal number of towers destroyed after the first 3 minutes, sudden death is enabled, a mode allowing an additional minute in which the next player to destroy a tower wins.
 * If no tower is destroyed within the next minute, the game will end with a draw and both players will not gain or lose any of their Trophies.
