Many players mistake a bonus for "free cash," but mechanically, bonuses are extra play credits granted to your account to extend your gaming session. The most critical distinction to understand is the difference between your Real Money Balance and your Bonus Balance.
These funds are stored separately. Generally, the system utilizes your real money first. Once those funds are exhausted, the system switches to your bonus balance. Unlike real money, bonus funds cannot be withdrawn immediately; they must first be converted into real money by fulfilling specific conditions. Until those conditions are met, the bonus balance serves as a tool to explore more games and increase your potential playtime.
