This varies from time to time, so it is impossible to point out any specific online casino that always has the largest casino bonus on offer.
Generally speaking, the largest casino bonuses are reserved for high rollers willing to make a huge deposit to a casino. Sometimes these bonuses aren’t even advertised publicly; you need to be a member of the VIP Club to find out about them. If you are a high roller interested in making a huge deposit, it can be a good idea to contact the VIP Club to see if you can negotiate a nice bonus offer beforehand.
With that said, simply going after the biggest casino bonus available online is not necessarily a good idea, due to several reasons.
- Your long term satisfaction with an online casino will most likely depend on other factors than one big bonus.
- Will you be able to fulfill the wager requirement of this huge bonus within the alloted time? This will be especially difficult if wagers on the games you prefer to play do not count fully towards the wager requirement.
- Sometimes a small bonus offer will actually be a more generous offer than a big bonus offer. Always check the fine print about deposit requirements, wager requirements, withdrawal rules, win-limits, etc. If you want to maximize your bankroll, seek out the bonus offers that actually provide great value rather than simply allowing yourself to be mesmerized by a big bonus amount.A €25 no deposit bonus with a 10x wager requirement for wins can be more generous than the €10,000 deposit bonus offer that requires a huge deposit, has a 45x wager requirement based on deposit + bonus and disqualifies you from betting on slots with progressive jackpots in the casino before you have fulfilled the wager requirement.
