Unlock Monster Bonuses

Types of Bonuses at Monster

We've split our promotions into several categories so you can quickly find what suits your style of play. Our Monster Casino promotions calendar refreshes regularly, giving you fresh reasons to log in every day of the week.

Monster Welcome Package

New players joining Monster Casino can claim a welcome package worth up to £1,000 plus 100 free spins, spread across your first five deposits (minimum £20 each). We've structured it so the rewards keep coming as you settle in:

This monster casino welcome bonus carries a 10x wagering requirement on the bonus or spin winnings before you can withdraw. The match funds and their winnings expire 30 days after crediting, while free spins and their winnings expire after 7 days. Deposits must go through our cashier directly - Skrill and Neteller top-ups don't qualify for this monster casino sign up bonus.

Sports Welcome Bonus

If you enjoy a flutter on the football or the races, our sports welcome offer lets you bet £10 and receive £30 in free bets, split into three £10 tokens for an accumulator, a Bet Builder and a live betting selection. The qualifying bet needs combined odds of 4/1 or higher across at least three legs.

Mystery Box

From Monday to Thursday, deposit £20 using code MBOX and open a Mystery Box for a random haul of 25 to 100 free spins. We've built in enough variety that regular players can pick up as many as 400 spins across the week.

Midweek and Weekend Wheel of Spins

Every Wednesday, a £20 deposit with code WED500 earns you a spin on our Wheel of Spins, with prizes ranging from 5 to 500 free spins. We run the same wheel Friday through Sunday under code WKND500, claimable once per day - one of our most popular ways to pick up monster free spins.

Sahara Riches Spins

Deposit £10 with code SAHARA25 and we'll credit 25 free spins on Sahara Riches: Cash Collect Max. This one's claimable up to three times, giving you repeated chances at this desert-themed slot.

Trio of Fortune

Our monthly Trio of Fortune bundles four separate offers, each claimable three times - match bonuses, free spins on Merlin's Mirage, Book Of Atlas, and Buffalo Rampage - Hold & Hit. Every code carries a 10x wagering requirement to clear within 7 days.

Reel Legends Leaderboard

Deposit £10 with code LEGENDS and wager on Playtech's Vegas-category slots to climb our Reel Legends Leaderboard. The top 10 players share a £2,000 prize pool, with cash rewards carrying no wagering requirement at all.

Monster No Deposit Bonus

We don't currently run a straightforward monster no deposit bonus, but our Rewards Programme gives every registered player a way to earn free spins and bonus money simply by completing Missions and playing regularly - no extra deposit required beyond keeping your account active. Points collected in the Rewards Store can be exchanged for free spins, cashback and deposit bonuses, which is often just as valuable as a traditional no-deposit offer.

Monster Promo Codes

Most of our promotions run on a monster promo code system, meaning you'll enter a short code at the cashier before your deposit to unlock the offer. We update codes for our Mystery Box, Wheel of Spins and Trio of Fortune promotions regularly, so it's worth checking our promotions page before each deposit.

How to Use a Promo Code

1. Log into your Monster Casino account
2. Head to the Cashier section
3. Enter the relevant monster bonus code in the promo field
4. Make your qualifying deposit
5. Your free spins or bonus funds will credit automatically

Wagering Requirements and Bonus Terms

Every offer at Monster Casino comes with clear terms, and we recommend reading them before claiming. As a general rule, wagering sits at 10x the bonus amount, with contributions varying by game type - table games and jackpot slots typically contribute 10%, while video poker contributes 5%. Only one bonus can be active at a time; additional bonuses queue as pending until the active one clears or expires. Requesting a withdrawal before wagering is complete will void any active or pending bonus, so we always suggest finishing your wagering first.

Our Rewards Programme

Beyond individual promotions, every player at Monster Casino is automatically enrolled in our Rewards Programme. You'll earn points by completing Missions - trying new titles, triggering bonus features, or hitting deposit milestones - and by simply playing our monster slots. Points climb your Level, unlock Badges, and place you on our Leaderboard, where top spots pay prizes and early access to new releases.

• Points redeemable in the Rewards Store for free spins, bonus money and cashback
• A minimum £10 deposit is needed to collect or spend points
• Store items expire 30 days after purchase
• Winnings from store-bought free spins are capped at £20

Payment Methods for Your Bonus Deposit

To qualify for most offers at Monster Casino, your deposit needs to go through our cashier using an eligible method. Here's a quick look at what's available:

Note that Neteller and Skrill deposits are excluded from every monster casino bonus, so we suggest choosing a different method if you're aiming to claim an offer.
