Top casino sites are constantly battling for each player, with the winner being you.  The competition between the different brands has brought out their A-game in terms of welcome offer for new UK players. Check out the following, most popular types of sign up bonuses offered by trusted casino sites:

• Matched Deposit – The most common and straightforward type of online casino bonus offers. The best casino websites will match a first deposit up to a certain amount, i.e. a £200 casino bonus means that the first deposit will be matched with bonus funds up to £200
• Welcome Packages – Similar to ‘match deposit’, it normally applies to several deposits after the first, with varying percentage of each deposit matched. A bonus of a £2025 Welcome package would normally be split over four deposits, with varying amounts and percentage limit to each deposit.
• Cashback Rewards – Some online casino bonuses aren’t presented in cash value or money equivalence, but rather awarded based on playing over a longer period, with the casino sites reimbursing players for a certain percentage of accumulated losses.

It is worth mentioning that at times, the best casino websites will combine one or more of these bonus types into one very enticing online casino bonus offer for online casinos UK players.
