Whilst the sheer number of online casinos trying to woo you to play their online casino games can be somewhat overwhelming, this fierce competition comes with the pleasant benefit that the promotional bonuses offered to keep and retain players have become pretty keen.

Of course it’s vitally important to choose where to play based first and foremost on the reputation of an online gaming site for secure and fair play but, if that box is ticked, hunting out the best online casino bonus packages can be a canny way to get the best value for money out of your online casino sessions.

Casino bonuses come in several flavours, but the most common incentive you’ll see advertised is the “Welcome Bonus” aimed at bringing new players through an operator’s virtual doors. These typically break down into two types – the ‘no deposit’ bonus and the ‘match’ bonus. The first is a very attractive bonus to any new player seeking to explore a site’s online casino games, since it’s a gift of a bundle of free cash to splash on your entertainment without requiring any deposit into your new player account after signing up.

The ‘match’ bonus is a complementary incentive of free bonus money that is calculated as a percentage of a player’s first deposit of real money into their account. The common figure for this is 100% so it effectively doubles your spending power, matching your first deposit pound for pound up to a specified limit.

Wagering Requirements

However, the winnings from these bonuses may be limited to a certain amount of money and the winnings can be withdrawn only after the set wagering requirements have been met. The wagering requirement is an amount of money which must be wagered through before the winnings can be withdrawn.

And that amount is usually multiple times the bonus amount, or the bonus plus the deposit amount.

For example, the wagering requirement may be 50 times the bonus amount, or 30 times the bonus and the deposit amount. Not all games contribute towards the wagering requirement equally. Most, if not all Blackjack variants contribute very little, or even don’t contribute at all.

A wagering requirement is an amount that is needed to be wagered before you can withdraw the bonus or any winnings. For example a wagering requirement of 20 times the sum of your deposit and bonus amount. E.g. for a 100% deposit match when depositing £20 and a wagering requirement of 20X = £20 deposit + £40 bonus x 20 = £1,200 so you will have to play games to the value of £1,200 before making a withdrawal.

Contribution Percentage

Most casino bonuses will have a Contribution Percentage which will apply to the wagering requirement. Slots usually have a 100% contribution and table games 10%.

So using the wagering requirement example if you played on a slot then all off your wagering will go towards the wagering requirement but if you played on a table game, say Blackjack, only 10% would go to the requirements. Playing blackjack with £1,200 requirement, at 10% would mean wagering £12,000.

Wagering requirements will have to be met before withdrawing any cash winning from a bonus. A contribution percentage applies to these wagering requirements. Slots usually have a 100% contribution and table games 10%.

We set out each bonus’s ‘Key Qualifying Criteria’ (KQC) please read these to ensure you meet the requirements. The KQC will also stipulate if you need to use a bonus code and if one is required what the code is. The KQC will also set out any wagering requirements that are needed to withdraw any cash won with the bonus.
