This is common in the online casino industry as it is vital they attract new customers due to churn. This is where you come in, you can claim a generous welcome bonus, gamble with more money than you normally would, and have the potential to win even bigger! Therefore, new online casinos that we add will usually provide the largest and most generous casino bonuses in order to gain traction and attract a higher volume of customers.

There are many bad actors in the online casino world, however, Gambling Geek only lists trusted gambling websites which are either licenced and regulated by the UKGC (UK Gambling Commission) and Malta Gaming Authority. We are dedicated to a safe and secure environment for our customers and this is backed up by our £500 Deposit Guarantee.

A bonus code is a password, this could be a word or series of numbers that you have to enter in the casino registration or deposit phase to activate a bonus.

In 2022, more checks on affordability and sources of income are done by operators, but hey, if you have the money to play with, then you are very welcome.

Some operators have pre-determined games you need to play on with the free spins, some don’t. You may also be able to have a crack at a progressive jackpot slot for the chance to win really big!
