One of the main reasons that players love to play at new mobile casinos in the UK is that these casinos often have the most competitive welcome offers and promotions. With that said, the following are the types of offers you’re likely to find at new mobile casinos in 2021.


The most common new mobile casino offers you will come across are welcome bonuses. These offers are exclusive to new players and are usually awarded as a no deposit bonus after completing registration or as a deposit bonus once you’ve made your first deposit. A match deposit bonus (e.g 100% Bonus up to £100) and/or free/bonus spins (e.g. 150 Free Spins) are common first deposit welcome promotions. Examples of new mobile casinos offering welcome bonuses and/or free spins include Casino, GatoBet and STS.


Free Spins are popular new casino offers. Also sometimes called Bonus Spins, these are real money spins with a pre-designated value (e.g. £0.10 per spin). Usually, players can claim a certain amount of free spins (e.g. 50) that can be used on one or several select slot games. It is common for this promotion to be included as part of a welcome offer, a reload offer, loyalty/VIP programme reward, and even as prizes for tournaments or other promotions. Examples of new mobile casino offering free spins include STS,, GatoBet and Kwiff.


Reload bonuses are for existing casino payers. They are deposit bonuses that are sometimes a part of casino’s regular ongoing promotional scheme or VIP programme. That being said, these promotions are often given to loyal players, with the biggest deposit bonuses reserved for the high rollers. Additionally, sometimes reload bonus offers may also include offers of free spins or special invitations to claim other perks. and GatoBet are examples of casinos that can offer reload bonus promotion to mobile players.


Cashback bonuses are refunds given to players by the casino. Essentially, you are refunded a portion of your net losses over a specific period of time (e.g. daily, weekly, or monthly cashback). Cashback bonuses may also be available only on certain days and on specific games. It is common for cashback to be a part of loyalty and VIP rewards schemes. That said, GatoBet is an example of a new mobile casino that offers Cashback Weekends, where players who play table games during the weekend can get up to 15% cashback on their deposit losses.

Yes. If you are a resident of the United Kingdom and are 18+, you can legally gamble online via your desktop, mobile or tablet device at legitimate sites that hold a licence from the Gambling Commission (UKGC).

These casinos must adhere to the strict protocols and rules put forth by the Gambling Commission. Failure to do so results in penalty and, in severe cases, legal action. We only review and recommend new mobile casinos that are legal in Britain.
