SlotsMillion Casino Online UK Casino Review & Bonus

We measured the return new players could expect to receive from a first deposit bonus at every UK online casino. The value of each first deposit bonus was determined by running the welcome bonus offer and conditions through a custom formula which we call ABV100 to determine exactly how much you should expect from a first deposit bonus when you make a £100 deposit. This is how well SlotsMillion Casino did in our first deposit bonus test.

Unfortunately, SlotsMillion online casino did not have a promotion for new depositing players when we last tested. While SlotsMillion Casino’s current welcome bonus is nonexistent, we will update the review if they begin offering a promotion for new players.
