Clash of Clans is a freemium mobile strategy video game developed and published by Finnish game developer Supercell. The game was released for iOS platforms on August 2, 2012, and on Google Play for Android on October 7, 2013. The game is set in a fantasy-themed persistent world where the player is a chief of a village. Clash of Clans tasks players to build their own village using the resources gained from attacking other player's villages or producing them at own village. To attack, players train different kinds of troops using resources. The main resources are gold, elixir and dark elixir. Players can conjoin to create clans, groups of up to fifty people, who can then participate in Clan Wars together, donate and receive troops, and chat with each other. Clash of Clans was released to generally positive reviews from critics. Four spin-off games in the same universe of Clash of Clans were developed by Supercell. The first, Clash Royale, was released in 2016. The other three, Clash Quest, Clash Minis, and Clash Heroes, were announced in April [login to view URL] Base A player attacking another player's village in the builder base game mode Following an update on May 22, 2017, Supercell released the new "Builder Base" game mode to the game. It allows players to sail to a new island and create a new village with a different set of buildings. In the "Builder Base" game mode, players can attack each other's bases simultaneously. The player who deals the most damage or getting more stars can get rewards such as gold, elixir, and trophies. However, the gold and elixir can only be won for the first three victories made by the player within a twenty-four hour timeframe, but can continue attacking for trophies afterwards. Players can spend gems to speed up the in-game 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. A new hero, the Battle Machine, was also introduced along with this update. It is the only hero in the game that has a reusable ability named Electric Hammer. In March 2018, Builder Hall level 8 was released while the June 2019 update brought Builder Hall 9 which is currently the highest Builder Hall level. This update also brought OTTO Hut, a secondary builder that can only be unlocked by finishing a number of in game challenges. When unlocked the master builder can be moved between the Builder Base and the Home Village. Clan games and magic items In December 2017, Supercell introduced the Clan Games where clan members could work together to complete tasks, which would then earn clan points. When enough points are accumulated, a new reward tier unlocks, and players can select one reward from each unlocked tier. This update also introduced Magic Items, obtainable as rewards from Clan Games and through events. These items can be used e.g. to get resources, finish upgrades, or briefly add levels to troops or [login to view URL], release, and marketing Jonas Collaros, one of the coders in the Clash of Clans team, speaks about the game's design at an event Clash of Clans was developed by Supercell, the company behind other popular mobile games like Hay Day.[31] The game took six months to develop with the gameplay changing little over the course of development.[32] According to Supercell's Lasse Louhento the development team encountered no major hurdles during this time.[32] Inspiration for the game included the games Backyard Monsters and Travian with the art style being influenced by old Super NES and arcade [login to view URL] the art style was more cartoon based but this was changed as the team worried it would alienate the more hardcore segment of their audience.
