Casino Bonuses and Free Spin Packages Explained

New Player Offers – Welcome Bonuses and Deposit Bonuses

Almost every online casino will offer a welcome bonus, which helps to attract and incentivise new audiences to play their online casino slots and casino games.

The online casino sites can be very competitive when it comes to their casino bonus offers, so it’s well worth doing your research to ensure you’re getting the best deal you can. We offer every type casino bonus so if you are looking for 50 free spins we got that covered if its a cash bonus that you are searching for check out £5 free no deposit section.

What are the wagering requirements for an online casino game?

Although wagering requirements differ for each operator, it essentially works as a multiplier to work out the number of times a player must play their bonus before they can withdraw funds to their bank account.

For example, a £25 slots bonus which has a 5x wagering requirement would mean you would need to play at least £125 on a game, before being able to withdraw the winnings.

What about casino bonuses with no wagering requirements?

Wager-free casino & slot bonuses are less common, but we have come across them here at SpinBonus before, so it’s worth keeping an eye on our top 10 casino bonus chart for any casino bonus with no wagering requirements.

How to identify the best casino bonus for me

There are lots of different factors to take into consideration when it comes to picking the best casino bonus. The one you choose will depend on your deposit preferences and casino gaming style.

For new players, seek out the casinos with the best welcome bonus offers. This is a great place to start, but it’s worth reading the terms and conditions before hitting ‘play’.

Also, consider casinos which offer free spins as part of the deal. This is known as a no-deposit casino bonus. Some operators even offer ‘free-play’ which is a great way to test and try a few different games, without running the risk of losing real money while you find your feet.

What are free spins and how do they work?

Free spins are usually awarded to online slot players as part of an incentive such as a welcome bonus or another kind of promotion. Operators usually allow them to be used across all of the online casino slot games on the site. But it is worthwhile reading the significant terms and conditions on our site to double-check.
