How Online Casino Bonuses Work

Casinos want you to come in and put your feet up... okay, the online UK casinos want you to put your feet up, virtually! "Get comfortable," they are saying. The best UK casinos want you to remember them for having the finest slots and bonuses. After all, besides actually coming out to your house to say "hello" personally, the next best thing the casinos can do is offer you a nice welcome bonus. It's the casino's way of saying "Hi, how are you? Come in, sit down, and enjoy the fun!".

Generally, you will be given a matched first deposit bonus - i.e. they will double your money on your first deposit, up to a certain limit. The limit normally ranges anywhere between £100 to £500. Do read all the WR details when picking a suitable welcome bonus for you. The WR determines how much extra bets you will have to make in order to be able to withdraw your bonus-related winnings. Let's hope you keep winning on all your deposits and this isn't an issue for you!

Complementary Spins are another sweetener in the deal! Normally, these spins are awarded to new customers for certain slots. Other perks of the top UK online casinos are reload bonuses, weekly competitions and cash prizes. Let's just say you won't be bored!

Time for you to decide

You've noticed by now that each of these UK casinos offer something unique. There will probably be one extra bonus with each one that catches your eye. Don't forget to check out the slots they have available, too. When you find a casino with the bonuses and slots you want then you're onto a winner! Always check out the WR and read the full terms and conditions - boring, we know, but it's worth taking the time to do it. You don't want any WR surprises when you go to withdraw your winnings now, do you?
So, best of luck, happy bonus hunting, and enjoy those slots!
