Most of the time, slots contribute 100% towards the wagering requirements.
What is an Online Casino?
If a cas top free spins casino player has to wager £1000 for example, the casino site should give you 30 days at least. When there are not any wagering requirements, 7 days is common. The longer the expiry time the better and it is crucial to know this before signing up as losing a bonus because it has expired is a common cause of frustration among new players. Wagering contributions are how much each type of game counts towards meeting the wagering requirements in a casino bonus. These are often overlooked but very important to consider. However, you may be required to wager some of the bonus on specific titles or certain types of games such as Jackpots. Once you figure out where you can wager the bonus, you need to know how much different games contribute.

We only consider online casinos that hold a gambling license from the UK Gambling Commission (UKGC). This is in order to prove games are fair and that players have a point of contact should they need any advice or guidance. Not only do gambling licenses allow online casinos to offer its services to UK players but the UKGC regulates everything from bonus terms to game betting limits to help ensure that players can enjoy online gambling responsibly and within their means. While there are a lot of enticing promotions and lucrative jackpots to be won on casino sites, we believe that playing games whether they be your favourite slots or poker with live dealers should be for fun.

However, playing can quickly turn into a problem if you begin chasing losses. If you see any signs of this happening, in yourself, a friend or family member, we recommend seeking advice. Here is some helpful information and advice on safer gambling. We prefer casino sites that encourage players to seek help and provide their own safer gambling measures such as spending limits and self-exclusion features. The sites we consider should at least provide links to responsible gambling organisations such as GAMSTOP, GamCare, Gambling Therapy etc.

These amounts vary between sites but they are typically £10 or £20. There are offers as low as £5 but sometimes the minimum stake is £10 so you may as well deposit £10 anyway or on the other hand there are simply less bonus amounts on offer because of the lower deposit. We weigh all of this up when analysing the best offers. The expiry time or validity period of an online casino bonus is the time frame you have to use the bonus and meet any conditions. Times vary especially if there are wagering requirements. The best online casino offers depend on the user preference.

We prefer free spins over bonus funds as there do not tend to be any wagering requirements. That said, wagering requirements should not put you off an offer as we strongly believe in playing on a casino site for fun. Wagering requirements specify how many times a player must bet the bonus amount before withdrawing winnings whereas wagering contributions indicate the percentage each game contributes towards meeting these requirements. For example spending your bonus on slots often contributes 100% to the requirements, while table games may only contribute 20%.
| Casino | High Roller Bonus | Min Deposit | Max Bonus |
|---|---|---|---|
| LeoVegas | 150% up to £1500 | £200 | £1500 |
