The House-Edge (or RTP%) of the Eligible Game
Some casino games have better odds than others, and this is where it gets slightly complicated. If you didnât know, the casino game with the best odds is Blackjack, and occasionally you can find No Deposit Bonuses that allow you to wager on Table Games. However, Table Games such as Blackjack rarely contribute 100% to your Wagering Requirements.
Why is this important? Well, it means that you have to play for a lot longer before you can fulfil your Wagering Requirements. When your No Deposit Bonus can expire, this is not ideal.
Your best chance is to wager on slots. The odds are worse, but if you claim a bonus eligible on a slot game with an RTP of 96% or over, you have a real shot.
