In-App Purchases

'In-App Purchases' are the act of purchasing Gems by paying Supercell real world currency in Clash of Clans. The game is free to download but has an option for players to purchase Gems with the real world currency. This type of game is called a 'Freemium' game, defined by the fact that you can play for free, but having Premium Items (Special Items) in the game requires that you spend real money. As it turns out lots of people use real money making Clash of Clans, as it is usually the top grossing game. The only In-App purchase is to buy gems, which varies in amounts you can buy. Many people use the gems to buy resources, or finish upgrades.
