Free casino money refers to promotional offers provided by online casinos to attract new players or retain existing ones. This bonus can come in various forms, such as no-deposit bonuses, free spins, or match bonuses on initial deposits. Players can use this free money to explore games without risking their own funds, making it an enticing way to experience the casino environment. However, it's essential to read the terms and conditions, as wagering requirements and restrictions may apply before any winnings can be withdrawn.
