Gacha games

Gacha games are video games that implement the gashapon mechanic. Gashapon is a type of a Japanese vending machine in which people insert a coin to acquire a random toy capsule. In gacha games, players pay virtual currency (bought with real money or acquired in-game) to acquire random game characters or pieces of equipment of varying rarity and usefulness. This is a variant of the loot box mechanic where players spend currency to acquire an entire set of random game items.
