ゲームはファンタジー世界をテーマにしていて、プレイヤーは村のチーフ(村のリーダー)になる。ゲーム内のプレイヤーは、ゲーム内での対戦機能を通じて他のプレイヤーから得た資源を使い、自分の村を建てることができる。主な資源は「ゴールド」「エリクサー」「ダークエリクサー」である。プレイヤーは他のユーザーが作成した50人以下のコミュニティである「クラン」に参加して、他のプレイヤーとともに「クラン対戦」をプレイしたりユニットを送りあったり、会話をしたりする事ができる。
また、クラッシュ・オブ・クランは多くの海外サイトから良い評判を得ている。
クラッシュ・オブ・クランはクランと呼ばれるコミュニティに参加し、ユニットを訓練して他のプレイヤーの村を攻撃したり、されたりして資源を稼いでいくゲームである。4種類の資源・通貨があり、ゴールドは他のプレイヤーの攻撃から村を守る為に使用される、エリクサーとダークエリクサーはユニットを訓練したり呪文を生成したり、もしくはアップグレードするのに使われる。エメラルドは特殊な通貨である。すべての攻撃は成功度により0から3つの星数で判定され、また攻撃は最大3分間で行われる。
The game also features a pseudo-single player campaign in which the player can attack a series of fortified goblin villages and earn gold, elixir and dark elixir (levels 51-75 only). The game starts with two Builders, but the player can have up to five builders through buying them with gems.
ゴールドやエリクサーを得たりためたりする為には、プレイヤーは金山は金庫、あるいはエリクサーポンプはエリクサータンクをそれぞれ建設する必要がある。
エリクサーは新しいユニットの解禁や、ユニットのレベルアップ、クロスボウ（タウンホール9からの防衛施設）の補填、あるいはいくつかの建物のレベルアップに使われ、それらは他のプレイヤーの攻撃に直接的に関係する。ゴールドは防衛施設の建設や、タウンホールをアップグレードしより高いレベルの建物を解禁する為に使われる。タウンホール7からはダークエリクサーが解禁される。ダークエリクサーはユニットやヒーローの訓練やアップグレード、闇呪文の生成（タウンホール8で解禁）、更にインフェルノタワーの補充（タウンホール10からの防衛施設）にも使われる。
タウンホール11で解禁されるイーグル砲はエリクサーで補充される。タウンホール11では新しいヒーロー、グランドウォーデンも解禁される。グランドウォーデンだけはエリクサーを使ってアップグレードされる。ダークエリクサーを得たりためたりする為には、ダークエリクサーポンプかダークエリクサータンクを建設する必要がある。タウンホールではタウンホールが防衛施設と返歌する、ギガテスラが登場する。
プレイヤーが建設できる防衛施設は、「大砲」「アーチャータワー」「迫撃砲」「隠しテスラ」「トラップ」「ウィザードタワー」「対空砲」「ボムタワー」「クロスボウ」「インフェルノタワー」「イーグル砲」がある。また、プレイヤーはタウンホールのレベルに合わせてレベルを上げることのできる「壁」を建設可能だ。
このゲームでは2種類の兵舎と2種類の呪文工場(それぞれ兵舎、闇の兵舎、呪文工場、闇の呪文工場)がある。兵舎ではユニット・闇のユニットをエリクサー・もしくはダークエリクサーを使って訓練していく。呪文工場も同じように、エリクサーやダークエリクサーを使って生成する。すべての呪文やユニットは違う状態を持つ。プレイヤーが村を発展させて行くと、新しいユニットもしくは呪文が解禁できるようになる。
さらに、援軍を収容できる3種類の突破兵器を作成できる、突破兵器工房がタウンホール12で解禁される。
Clans are groups of players who join together to support each other, either materially (donating troops) or verbally (giving advice). Players can join clans once they rebuild the special Clan Castle building early on. A major component of the gameplay of "Clash of Clans" is clans facing off against one another in the "clan wars". Clan leaders and co-leaders can begin wars against other clans. Each clan is then given one "preparation day" and one "war day." When a player attacks a member of the opposing clan, they receive stars based upon the amount of destruction they cause to the opponent's community. Each player is limited to two attacks per war, and the team with the most stars at the end of the war day is declared victorious. If the two clans' number of stars are equal, then the victor is the one that has a greater percent of destruction. Players receive bonus war loot if he/she use their attacks in the war. This loot may be different on different bases and is decided by Supercell; the top base has the most war bonus loot and the last base has the least amount of bonus loot. If the clan wins the war, the bonus loot is fully delivered to the player but during a loss or draw one-third of the loot is delivered to the player. In the March 2016 update, 35v35 and 45v45 were removed. The available war sizes are 50v50, 40v40, 30v30, 25v25, 20v20, 15v15, 10v10 and 5v5. In the May 2016 update, Friendly Challenges were introduced to allow clanmates to compete amongst other clanmates, however these challenges do not provide loot or trophies and do not affect a player's army. In the October 2018 update, Clan War Leagues were introduced. Clans would fight seven other clans to advance to the next league and earn league medals by earning stars in Clan War Leagues. The clan in the group with the most stars will be promoted to a higher league, while the clans in the group with the least stars will be demoted to a lower league.
A new update to the game on May 22, 2017 released a new game mode, known as the "Builder Base". Players can sail to a new island and create a new village, with a different set of buildings. In this mode, two players attack each other's bases simultaneously. The one with the most damage or getting more stars gets the gold, elixir, and trophies. You can only win loot from attacking three times in twelve or twenty-four hours, but can continue attacking for trophies afterwards. The player can spend gems for skip the period of time. The progress will be much faster in this base with the introduction of Clock Tower (temporarily speeds the process in the entire Builder Base) and Gem Mine (spawns gems at a very slow rate). The update also introduced a new hero, the Battle Machine. It is the only hero in the game with a reusable ability named Electric Hammer. In March 2018, Builder Hall level 8 was released, which is currently the highest Builder Hall level.
In December 2017, Supercell introduced the clan games, at first a one-off event where clan members could work together to complete tasks, which would then earn clan points, but there has been plans to make it a weekly event. When enough points are accumulated, a reward tier would be unlocked, and players can select one reward from each unlocked tier. This update also introduced Magic Items, which could be used to enhance certain aspects of the player's village. Magic items are obtainable as rewards from clan games and through events.
"Clash of Clans" was created by Zack Ferry and developed by Supercell, the company behind other popular mobile games like "Hay Day". The game was released for iOS platforms on August 2, 2012, and on Google Play for Android on October 7, 2013.
The game is heavily promoted. In February 2015, Supercell released their "Clash of Clans" Super Bowl XLIX commercial, featuring Liam Neeson parodying his character from "Taken". On February 2, Business Insider reported the ad as the 5th most watched Super Bowl ad, though on February 6, VentureBeat reported the ad was the most viewed of those that appeared on the Super Bowl. YouTube users later voted the advertisement the second best Super Bowl ad, behind Nissan's "With Dad" ad.
On September 23, 2015, Taiwanese singers JJ Lin and Jimmy Lin released the game's theme song "全面开战" ("Start a war totally" in English), which was sung in Mandarin.
"Clash of Clans" has received generally positive reviews. The iOS version holds an aggregate score of 74 out of 100 on Metacritic, and 80% on GameRankings.
Gamezebo's Leif Johnson was impressed, scoring the game 4.5 out of 5. Although he felt the gameplay was heavily skewed to encourage the player to purchase gems, he praised the addition of a single-player campaign. He concluded that ""Clash of Clans" is a simple game, but that's more of a strength than a weakness. It's simple enough to provide quick, painless matches on an iPhone in an idle moment, and there are enough different units to choose from in the battle mode to make playing against other players endlessly rewarding. Best of all, the option to fight against NPC goblins gives "Clash of Clans" a small edge over similar strategy games that rely almost entirely on player-versus-player combat."
Pocket Gamer's Peter Willington was equally impressed, scoring the game 9 out of 10 and giving it a "Gold Award". Reviewing the game several months after it was released for iOS devices, Willington praised the game for requiring real strategy to play. He wrote that the gameplay was built on the progression of "requiring more and more sophisticated units, asking you to strategise and really think about which elements you should focus on building within your camp." He concluded that ""Clash of Clans" is a superb game, freemium or otherwise, with more nuance than most give it credit for. That's why it's passed the test of time since its launch and still has an active community devotedly constructing elaborate fortresses in the hope of becoming invincible."
148App's Rob Rich scored the game 3.5 out of 5, writing "It's great to play an online freemium game that doesn't shy away from the single-player experience but also offers up some honest-to-goodness direct interaction, which is a very rare combination these days. It probably won't warm the hearts of any haters out there, but it does give genre fans something with a bit more action and strategy than they might be used to." Tom's Guide enjoyed the player interaction.
Modojo's John Bedford was less impressed, scoring the game 3 out of 5. He was critical of freemium gaming in general, writing "The novelty hasn't just worn off this particular style of greedy gaming, it's shriveled up and condensed itself into an infinitely dense singularity of self-loathing." Of the game itself, he concluded, "This is a game that follows in the footsteps of no small number of titles that have made feverish demands on our wallets in exchange for just a slightly thicker slice of the gameplay. It's possible you have an unending appetite for these micromanagement titles, in which case we recommend getting heartily stuck into Supercell's latest game. While "Clash of Clans" brings something new to accompany its competent but unexceptional empire gameplay, for most of us it'll be a case of too little, too late."
"Clash of Clans" became an App Store top 5 download between December 2012 and May 2013, and this success has been described as helping to usher in a new era in single player gaming on mobile devices. In 2013, "Clash of Clans" was the third-highest game in revenue generated on the App Store and number one on Google Play.
In February 2014 it was reported that the game was generating $654,000 in daily revenue for Supercell. In 2015, the game was the top grossing app on both the App Store and Google Play, with an estimated revenue of 1.5 million dollars per day.
