Casino bonuses and freebies

Casino bonus – this a very generic term that refers to any bonus or special offer that casino gives to the players and it can come in all shapes and forms.

Welcome bonus – this is the first bonus that you will receive from a casino when you start playing. Different online casinos give different welcome bonuses starting from £100 and going up to £1,500 pounds. When choosing a casino try to get the best deal possible for your initial investment. Welcome bonus can come in a form of a package that includes 2, 3, or even 5 different welcome bonuses or just one basic bonus. Welcome bonus can also be a deposit and no-deposit bonus.

Deposit bonus – this is a bonus that matches your deposit in the casino with a percentage that casino gives you back to play with. The match can start from 25% and go up to 200% but as an average, the most common ones are 100% matching deposit bonus. Deposit bonuses are not always welcome bonuses as many casinos run a lot for different campaigns, and you can get a deposit bonus on a regular basis.

No-Deposit bonus – this is a type of welcome bonus when the casino is ready to give you some cash just for your registration details when you sign up and before you even deposit for the first time. It is a great bonus, which is unfortunately not very common, but if you see it, snatch it immediately.

Most casinos give free spins on the super-famous Starburst slot, but free spins for other slots are available as well. Free spins most of the time will be given to you as a part of the welcome package and the range can be anywhere from 10 to 250 free spins. If you sign up for casino newsletter, you will also most probably get free spins for the slots that are being launched all the time.

Cash back – many online casinos are offering part of the money that you wager and play in form of a cash back. It can be a percentage of your lost money or a set amount per month, but we always recommend signing up for this kind of bonus as you get the most bang for your casino investment, since none of us can realistically be winning all the time.

Cash Drop – this is usually a type of casino promotion when there is a certain amount of cash that will be given to one lucky winner or shared between many players who achieved certain results in particular promotion. For example, £10,000 pounds will be shared between 50 players who made deposits not less than £30 pounds and were randomly drawn to be the winners. The rules for cash drops vary a lot, so make sure you carefully read the terms and conditions of such promotions.

Tournament - many casinos organise regular competitions or tournaments be it for slots, poker, or other types of games. Here you will get a chance to be the tournament winner if you complete certain challenges and get on the top of the leader board that shows the results for the best players. These tournaments most of the time require you to opt-in, which means you need to decide to participate and click a button or fill in a simple form to be in the tournament.

Loyalty Program – many casinos have their loyalty programs in place and award you loyalty point for your activity in the casino. The rules are always different but you can get the points for depositing, playing certain games, completing challenges and other types of casino actions.

Loyalty Points – are the point earned in the loyalty program, which can then be exchanged for gifts, merchandise, bonuses, free spins, cash, trips etc.
