What are microtransactions in mobile games?

Microtransactions are all types of financial transactions that occur in mobile games. This includes in-app purchases and subscription transactions. By making microtransactions, players can acquire different in-game items (e.g. currencies, characters, boosters).

Microtransactions are an important revenue source for free-to-play mobile games, and games that contain them are often referred to as “freemium games”.
