Book Of Santa:
Book Of Santa at Mr Green 2026 - Complete Guide for United Kingdom Players

Why Play Book of Santa at Mr Green

Mr Green's dual licensing under the Malta Gaming Authority and the UK Gambling Commission places it under two of the stricter regulatory regimes in the industry, which matters for a high volatility title like Book of Santa where players want confidence that the RNG behind its 96% RTP is being checked independently. The 24 hour withdrawal window is a straightforward, single figure rather than a range that depends on the payment method, so a strong free spins result does not sit in a review queue for days. Founded in 2008, Mr Green carries close to two decades of operating history behind its current 4.4 rating.

Getting Started: Signup & First Deposit

Opening an account at Mr Green and getting to your first Book of Santa spin takes six steps, from registration through to activating the welcome offer. None of it requires anything beyond a valid ID and a supported payment method.

1. 1
   Create Your Account

   Go to mrgreen.com and select Join or Register. You'll be asked for your name, date of birth, email address, currency and a password. Double-check your date of birth field before submitting, since an ID mismatch here is the most common reason a new account gets flagged for extra checks later.
2. 2
   Verify Your Email

   Mr Green sends a confirmation link to the address you registered with. Click it to activate the account before attempting a deposit. If it doesn't arrive within a few minutes, check your spam folder before requesting a resend.
3. 3
   Make Your First Deposit

   Head to the cashier and choose from Visa, Mastercard, PayPal or Trustly. The minimum deposit is €20. Card and PayPal deposits are typically instant, so you can move on to claiming the bonus right away.
4. 4
   Activate Your Welcome Bonus

   Enter the code MRGREEN100 during the deposit step to trigger the 100% match up to €100 plus 200 free spins. The bonus carries 35x wagering, so read the table below before deciding how much of your deposit to put toward it.
5. 5
   Find Book of Santa in the Game Lobby

   Use the search bar and type "Book of Santa," or filter the slots section by provider and select Endorphina. The game thumbnail shows the Book symbol artwork, so it's easy to spot once you're browsing the Endorphina row.
6. 6
   Start Playing Book of Santa

   Set your stake anywhere between $0.01 and 45 EUR per spin, then hit spin or switch on autoplay. If you'd rather see how often the Book scatter triggers free spins before betting real money, load the free demo first - it runs on the same RNG and 96% RTP as the cash version.

Welcome Bonus - Complete Breakdown

The Mr Green welcome offer is a 100% match up to €100 plus 200 free spins, unlocked with code MRGREEN100 on your first deposit of at least €20. The bonus funds carry 35x wagering, meaning you need to bet 35 times the bonus amount before any winnings from it can be withdrawn. Mr Green has not published a separate contribution percentage for Book of Santa, so the effective playthrough listed below is the standard 35x wagering figure applied directly to the bonus amount rather than a game-specific adjusted total.

How to Play Book of Santa at Mr Green

Every round at Mr Green starts the same way as it would anywhere else Endorphina's game runs: set a stake between $0.01 and 45 EUR, then spin the five reels or let autoplay handle a set number of rounds for you. Payouts scale with symbol rarity, and the Book works as both the top-paying wild and the trigger symbol for the free spins round - land three or more anywhere on the reels and you're into 10 free spins with one randomly chosen symbol expanding to cover full reels on every winning hit. That expanding-symbol mechanic is where most of the game's 500,000x max win potential sits, and at a 96% RTP with high volatility, the free spins round is the part worth understanding before you bet big. Mr Green offers the demo version of Book of Santa with no registration or deposit needed, running on the identical RNG and RTP as real money play, which makes it a reasonable way to watch how often that Book scatter actually lands before switching to cash stakes.

Withdrawal & Payment Methods

Mr Green supports four payment methods for UK players: Visa, Mastercard, PayPal and Trustly. Withdrawals across these methods complete within 24 hours once a request is approved, which is a single consistent figure rather than a method-by-method range. That approval step is tied to the KYC process covered below, so the 24 hour clock generally starts once your account is verified rather than the moment you click withdraw.

KYC Process at Mr Green

As an MGA and UKGC licensed operator, Mr Green is required to verify player identity before processing withdrawals, which typically means uploading a government ID and a recent proof of address document through the account verification section. Mr Green has not published a fixed turnaround time for this check, so treat the 24 hour withdrawal figure as the payout window once verification is complete rather than the total time from request to funds landing. Submitting clear, current documents at signup rather than waiting until your first withdrawal request is the most reliable way to avoid delays. If a document is rejected, the cashier or support chat will usually specify what's missing rather than leaving the request pending indefinitely.

Mobile App at Mr Green

Mr Green's app store listing details, including APK size and iOS availability, are not part of the data behind this guide, so treat any download link found outside mrgreen.com with caution. What is confirmed is that the site is built to run through a mobile browser on both Android and iOS. Book of Santa's 96% RTP, autoplay, and free demo mode all carry over to mobile play unchanged, since it's the same Endorphina game engine regardless of device.
