gacha

A gacha game (Japanese: ガチャ ゲーム, Hepburn: gacha gēmu) is a video game that implements the gacha (toy vending machine) mechanic. Similar to loot boxes, gacha games entice players to spend in-game currency to receive a random in-game item. Some in-game currency generally can be gained through game play, and some by purchasing it from the game publisher using real-world funds.
Most gacha games are free-to-play (F2P) mobile games.
The gacha game model began to be widely used in the early 2010s, particularly in Japan. Gacha mechanics have become an integral part of Japanese mobile game culture. The game mechanism is also increasingly used in Chinese and Korean games, as well as European and American games.
Gacha games have been criticized for being addictive, and are often compared to gambling due to the incentive to spend real-world money on chance-based rewards.
