クランとクラン対戦
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.
ビルダーベース
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.
クランゲームと魔法アイテム
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.
