About us
The BigBookofSlots.com is owned and run by Triple Hat Media Ltd. THM is a registered marketing company specialising in Affiliate Marketing.

Knowledge Base
How To
We’ve made this site simple to use and very user-friendly. All you need to do is hover over the flip card, all the info you need about the game is on the reverse. What it is, where to find it and what the RTP % is. Click on the “where to play” button and it takes you to the game provider intro page and which Casinos offer that game.
Welcome Bonuses
This is an affiliate site, so there will be Bonus information somewhere. Every Casino offers a “fabulous” Welcome Bonus, or sign-up bonus. Each bonus is individual to that casino, so you will need to read and agree to their Terms and Conditions before you can play. Some welcome bonuses are better than others, but that is something for you to decide. We have a general guide of what to look for and more importantly, when to take the bonus or when to pass.
Age Verification
This website has casino game content that is intended for adults only. By entering you need to confirm that you are 18+ years or older. Each casino has age restrictions set in place, so proof of ID is always needed when registering with a gambling site. You will need to provide proof of your age and identification by Photo ID, proof of address, and a copy of Credit Card details. In extreme cases, a notarised documentation may be required. Please note that by continuing to browse our website you agree to our Privacy Statement and T&C’s.
Real money Play, Demo Play
All of the games that we have advertised on this website are games that are available to play in either Demo mode (free version) or in real money mode (pay and play version). Each game is mobile and desktop-friendly and is available at more than one casino. Games that are “network” provided will all have the same spin bonuses, booster pots, and prize pots, regardless of where you play them.
Casinos
There are as many casinos on this website as there are games. That gives you the upper hand when it comes to picking one that is right for you. So what should you look for in a casino? The answer is not Welcome Bonus! Look past the free spins and deposit match offers and look for a Gambling Licence and if they are registered to a Gambling Commission. Also important is to look at their Customer Services. If they offer one-to-one support or chat options, it’s usually a good sign. Check out the wagering requirements and Terms of service before you start to play.
SET YOUR LIMITS – Gamble Responsibly
RTP
The RTP % or Return to Player percentage is the term casinos use to describe the pay-out percentage given back to players on all the money wagered on that specific game or slot over time.
How does the RTP impact an individual player? This is a heads-up to let you know what the casino earns on a specific game. It does not impact your game, and it does not stop you from winning a jackpot or guarantee you a win. The RTP is calculated on all bets all players make on that game, not just your bets.
As an example, let’s assume that the total bets placed on that specific game are 100 x £1 bets on a slot with an RTP of 90%. That means that over time, the players should get back 90% of all of the money staked on that game in wins. OR, look at this another way, 10% of all bets staked on this game go to the casino.
*Note: All RTP % shown on the flip cards are the recommended RTP for that game. However, individual casinos may vary.
The Book of… series of slots is so popular that most of the big names in iGaming have produced a Book of… Good news for us, and great news for you. The genius behind the idea comes from the original Book of RA, what came next is fabulous adaptations of that idea. The list of providers is long, but hopefully not complete.
Below is a list of all the brilliant game providers/designers that have gone the extra mile and created genius games, graphics, and soundtracks that we’ve fallen in love with. Show the love when playing their games, and keep an eye out for their next Book of…
Ready, Set, Play!
Now you know what game is on offer, what development house created that game, and more importantly where to find that game. All you need to do now is “flip the card” and select your casino of choice. There is usually more than one casino option, so you have a choice. Either click on the casino logo and go straight to the casino or click “Read more” and get a short heads-up about that casino first.
Have fun, good luck, and remember to Gamble Responsibly.
