Different types of UK Christmas online casino promotions

We’re just warming up for Christmas, and as time progresses, there will be more and more UK casino sites clamouring to shower both newcomers and their most loyal players with marvellous gifts. There truly is a casino Christmas bonus for everyone this year.

Christmas online casino promotions

These are Christmas game-specific promotions that you can find at many casino sites. As one might expect, such bonuses tend to be focused around Christmas-themed slots. Some casinos also run tournaments where you play specific Christmas-themed slots for a chance to win a share of a communal prize pot. 

Special Christmas sign-up offers

As a way of showing players gratitude for signing up to a casino site, the operator may offer a special casino welcome bonus or even multiple treats! These can range from Bonus Spins to cash bonuses. Who knows, one of them might lead to a bit of extra cash for Christmas presents this season.

Bonus/Free spins Christmas promotions

Free or bonus spins Christmas promotions aren’t that uncommon at UK casino sites during this season. Check our page regularly so you don’t miss out on the latest Casino bonus spins being offered at some of the top casino sites in the UK.

Christmas wager-free casino bonuses

A no wagering casino bonus is one that, yes, comes totally free of wagering requirements. This makes such a Christmas online casino promotion extra desirable! That said, as with all casino bonuses, do note the Terms and Conditions of the offer before committing.

Winter tournaments

Winter is the jolliest season of the year and one that most people spend indoors relaxing. This is the perfect time to join some fun and rewarding Christmas Tournaments for the opportunity to win some amazing prizes!

Giveaways and raffles

Raffles and giveaways are some of the most exciting Christmas casino bonuses around. Leading game providers like Microgaming, Yggdrasil, and NetEnt usually lay on Christmas online casino promotions like these so look forward to some super exciting offers from these outfits throughout December.

Why grab a Christmas online casino bonus?

Christmas online casino promotions are generous, giving you a great chance to check out what a casino has to offer at what sometimes is a very low price. Welcome bonuses are a good introduction to what new players can expect from the online casinos they join, and seasonal offers often advertise specific slots, either new or classical ones.

Why do casinos run online casino Christmas promotions – and what’s in it for you?

One of the reasons UK casino sites offer online casino Christmas promotions is to attract new players, as well as keep their most loyal UK casino players happy. Bonuses, depending on their size and what they include, can potentially boost your chances of winning in the games you choose to play at any UK casino site.

Casino Christmas calendar

A number of UK casino sites run calendar-style promotions that include a surprise casino Christmas bonus for each day of December. This can come in different formats. Some casinos go for the traditional 25-day Calendar, while others tend to draw it out by including a few extra days. 

An example of a casino Christmas Calendar is the one available at Videoslots, which runs from the 1st until the 25th of December.

How does an online casino advent calendar work?

An online casino advent calendar usually has promotions with wonderful cash prizes or bonuses for 25 days of December or more. Many UK operators tend to collaborate with game providers to bring you some of the best Christmas casino promotions out there.
