Gacha

A monetization mechanic where players spend currency (real or in-game) for randomized character or item draws, similar to capsule toy machines (gashapon) in Japan. Gacha mechanics are central to mobile games like Genshin Impact, Honkai: Star Rail, and Fire Emblem Heroes. The mechanic has been criticized for encouraging compulsive spending to collect rare characters. Many regions now require disclosure of drop rates; some have implemented spending limits.
