My Criteria for the Best Bonuses on WilliamsCodes

Below is our list of criteria that we used to review the top UK bonus code casinos and what exactly we look for in a quality online casino.

  • Personal Experience: I personally test out and play at all the sites I list. I redeem the bonus offers and promotions to see how easy it is, what the wagering requirements are, how easy it is to make a deposit and withdrawal, and how well the casino is run. If I have fun and win regular amounts, it gets my vote.
  • Promotions: The promotions have to be good to get my vote. I don't just want a signup bonus code. I want to be rewarded for my gameplay and have a reason to visit often. I look at the monthly deals and regular player promotions to make sure that they offer value for money and have acceptable wagering requirements.
  • VIP Rewards: Do I get more benefits by playing more? I look at the VIP programs and what the comp points can be redeemed for. I look at the different levels in loyalty programs and the additional benefits received by climbing the levels such as bigger withdrawal limits and more.
  • Game Selection: This is very important. I want to be entertained and that means there has to be plenty of games to play with new games added on a regular basis. I look at the graphics and features of the slots, how many ways there are to win, etc. I also check how many variations of table games there are too.
  • Device Compatibility: I like to play on the go when I'm out and about and especially while I'm stuck waiting for things. Mobile compatibility is a must and I check the gameplay and the game selection very carefully. I also make sure I can access all the casino features on my mobile devices and whether there are dedicated apps.


What is the difference between a Bonus and an Exclusive Bonus?
There are lots of different types of bonuses available at casinos including signup offers, no deposit bonuses, free spins and more. These are regular bonuses. Exclusive bonuses are special bonuses that I have agreed with the casino for readers who use my special link to sign up for an account. These offers aren't available anywhere else.

What is a Match Bonus?
A match bonus is where the casino will match your deposit by a fixed percentage up to a certain amount of money. For example, a 100% match up to £400 means that if you deposit £100 the casino will match this and give you an additional £100 meaning you have £200 to play with. The most you can deposit is £400. This differs for different casinos such as WillHill.

What's a wagering requirement?
Wagering requirements or play through requirements are terms that are set on casino bonuses that tell players how much they have to wager before they can make a withdrawal. They are usually displayed as 30x which means you have to wager your bonus amount 30 times before you can make a withdrawal. Wagering requirements will differ from casino to casino so be sure to check them.

Where do I find the best bonus codes?
The easiest answer to this is here on WilliamsCodes. I have all the best bonus codes for UK players so if you want to find a no deposit, free bet, or signup offer that is worthwhile, I advise you to check out all the offers on my site. The best promotional offer is the William Hill Bonus Code.
