A gacha game is a type of video game that uses a chance based system to let players obtain characters, items, or other in game rewards. The name comes from Japanese capsule toy vending machines called gashapon, where each purchase gives a random toy. In gacha games, this concept is recreated digitally. Players spend in game currency, which can be earned or bought, to receive a random reward from a large pool of possibilities.

The excitement comes from the unpredictability. Some rewards are common while others are extremely rare, encouraging players to keep trying for the items they want. Many popular mobile games use this system to keep players engaged and to support ongoing development through optional purchases.

Gacha games often feature colorful characters, collectible systems, and ongoing updates that introduce new items or events. While they can be fun and rewarding, they also require players to manage their spending wisely since the results are never guaranteed.
