CS2 gambling involves using in-game items, most notably skins, as currency to place bets on various gambling platforms. These platforms offer games of chance, skill, or both, giving players opportunities to win more valuable skins or other rewards. Skins in CS2 are cosmetic upgrades for weapons, ranging from common to extremely rare items. The rarity and aesthetic appeal of skins influence their market value, which can range from a few cents to thousands of dollars.
