How do you go about finding the best online casino at which to join up and play at? If you’re in the UK, check out our dedicated article on the best online casinos in the UK. We feature what we believe to be the best new and established UK licensed online casinos, all offering the latest slots, casino games and live casino options as of April 2025.
All online casinos featured in the above UK focussed article offer fantastic welcome bonuses for new UK players (18+ years).
When you sign up as a new player to any online casino, you’ll qualify for what is known as a welcome bonus when you make your first deposit. These normally come in the form of free spins on online slots and casino credit by way of deposit match bonus.
With the latter, a typical deposit match bonus might be 100% of your first deposit. For example, the welcome bonus could be “50 free spins and a £100 bonus”, meaning that if you were to sign up and deposit £100, you’ll get £100 matched by the casino and 50 free spins to boot.
A typical minimum deposit may be £10 which means you’ll get £10 back from the casino, matched, and you’ll still get the 50 free slot spins. A popular type of welcome bonus is the no deposit bonus.
If you’re after a casino bonus for spending less than £10, have a read of our article: the best £5 deposit bonuses for UK players where we’ve listed a choice of reputable online casinos and slots sites offering bonuses for depositing just a fiver.
Grab yourself free spins when you sign up and verify your age and identity without having to deposit anything at all. Remember though, all bonuses come with pretty stringent terms and conditions.
