Gameplay

Clash of Clans is an online multiplayer game in which players build a community, train troops, and attack other players to earn gold and elixir, and Dark Elixir, which can be used to build defenses that protect the player from other players' attacks, and to train and upgrade troops. The game also features a pseudo-single player campaign in which the player must attack a series of fortified goblin villages.

Buildings

To earn and store gold and elixir, players must build gold mines and gold storages and elixir collectors and elixir storages, respectively. Elixir is used to train new troops, carry out research in the laboratory to upgrade troops, to re-load X-Bows (available from Town Hall 9) and to build and upgrade certain buildings, mostly pertaining to buildings used in attacking another player's base. Gold is used to build defensive buildings and to upgrade the town hall, which allows access to more buildings and higher levels for existing buildings. At higher levels, dark elixir becomes available; this type of elixir is used to train and upgrade dark elixir troops and heroes, create dark spells, and fuel the Inferno Tower, a defensive building that is available only at Town Hall 10. To earn and store dark elixir, players must build dark elixir drills and dark elixir storages.

Open licensing is built within the existing framework of intellectual property rights as defined by relevant international conventions and respects the authorship of the work". Often cited is the William and Flora Hewlett Foundation term which defines OER as:
