Skin gambling involves using virtual items, typically cosmetic in-game items such as "skins," as virtual currency to wager on the outcome of professional matches or other games of chance. This practice is often associated with the community surrounding the popular game Rust, which allows players to acquire decorative skins through purchase or in-game rewards. These skins can be valuable, with rarer skins fetching higher prices. Skin gambling websites enable players to use their skins to place bets on esports matches, and they can wager as many skins as they desire. During the game, the skins that players are staking are removed from their inventory and locked. If they win the bet, they receive back their own skins along with the skins that their opponent gambled and lost, which are placed back in their inventory.
