What kind of rewards/bonuses do you like ?
It's good we have casinos trying to improve their site by asking for suggestions from their customers. Not many casinos sites do this and that's because they don't care about their customers feedback but just do as they feel like doing.
For reward and bonus, I like deposit bonus. Free spins and cashbacks are great but I love when I get bonuses on my deposit. It motivate me to deposit more and keep on gambling. Deposit bonus make me deposit not minding if I have money on the casino already.
Obviously I try not to over gamble so I don't get addicted and some times I end up mostly using the bonuses given for depositing to gamble with just few of my deposit money used for a bet unless I'm feeling too lucky to risk more of personal money.
Deposit bonus on most casino come with a wager requirement, which simply means that, (depending on what the wager requirement is) aside the bonus received, you must gamble with a greater part of your main deposit before you can be able to withdraw, without meeting the requirements, you won't be able to withdraw, I believe this requirement is put in place to prevent abuse, without it, gamblers will just deposit, claim the bonus, then withdraw their deposit and only gamble with the bonus.
