Gacha mechanics are a popular feature in many video games, especially in mobile games. They work like a lottery system where players spend in-game currency or real money to receive random items, characters, or upgrades. The excitement comes from the surprise of what you might get, similar to opening a pack of trading cards. Players often hope for rare or powerful items, which can enhance their gaming experience. These mechanics encourage players to keep trying for better rewards, creating a cycle of spending and collecting. Games like Genshin Impact and Fate/Grand Order use gacha systems to engage players, making them feel invested in their collections and achievements.
