The deposit bonus acts as a buy-in for a bonus.
For example, if you deposit $100 to buy into a 200% 40x bonus, the details could be as follows:
You receive a balance of $300.
You must wager this balance 40 times (i.e., $300 x 40 = $12,000).
You cannot place a bet exceeding $10 on a single wager.
Bonus buying is not permitted.
You must complete the bonus within a specified time frame.
Think of it as a challenge: to win, you need to successfully complete the wagering requirement. In this case, you must wager $12,000 using the $300 balance provided. If you meet this requirement, you can keep any remaining balance.
However, if you fail to reach the wagering target or violate any bonus terms, you will forfeit everything, including your current balance and initial deposit.
So, why would someone choose to play with a deposit bonus? The answer is simple: more balance means greater opportunities to achieve a big win, which is what most players are ultimately seeking—the chance to hit that elusive 10,000x win!
