Slot Details
The Midnight Marauder ClusterBreaker slot begins on a 4x4 grid with Cluster Pays. With symbols breaking into up to 4 matching symbols, there are more opportunities to form winning clusters: a winning cluster is created when 5 or more matching symbols appear directly adjacent to each other.
With a 10p minimum bet per spin, the most you can play in the UK is £5, or £2 if under 25: outside the UK, it goes up to 100 x your total bet. Use the plus and minus buttons or press/click the ‘Bet’ amount to change your bet. Non-UK players can use Turbo Mode and Autoplay (up to 1,000 auto spins).
The Midnight Marauder ClusterBreaker RTP rate is 96.1%, with 94% and 92% RTP variants also available. If you were to take a £20 balance and play at 10p a spin, below is the theoretical number of expected spins before running out of funds:
- 96.1% = 5,103 spins
- 94% = 3,317 spins
- 92% = 2,488 spins
In the medium to high volatility bracket, the hit frequency rate is 20.58%: this means a winning cluster will form every 1 in 4.86 spins. When it comes to payout potential, Midnight Marauder ClusterBreaker comes with 10,000 x bet max wins.
Midnight Marauder ClusterBreaker Expert Review
Theme, Audio + Symbols

With a crime/heist theme, the Midnight Marauder ClusterBreaker slot is the follow-up to Midnight Marauder (May 2022) and Midnight Marauder Dream Drop (July 2023).
Set inside a luxurious mansion, you’ll see the thief trying to crack the vault. The main character, known as Mr Midnight Jr, is hard at work and reminds me a little of The Bad Guys movie as it’s rather inviting and playful. This classic crime caper has a rather gentle soundtrack and has a touch of Inspector Gadget.
On the grid, you’ll see green, orange and red gemstones, wads of cash, perfume bottles, diamond rings and handbags: the handbag is the best-paying symbol, reward you with 20 x your total bet for 20 in a cluster. There is also a Wild symbol that substitutes for all paying symbols on the grid. Finally, there are Coin symbols which can trigger a bonus feature (more details below).
Midnight Marauder ClusterBreaker Mobile

With HTML5 technology used for all Relax Gaming titles, Midnight Marauder ClusterBreaker is available to play on mobile, tablet and desktop devices. It’s compatible with iOS and Android smartphones, in Portrait Mode.
Bonus Features
Midnight Marauder ClusterBreaker comes with cluster wins, a symbol splitting mechanic, doubling multipliers up to 1024x, Coin collections, random symbol splits and free spins with a higher starting multiplier.
ClusterBreaker
The game, you guessed it, uses a ClusterBreaker feature. This mechanic randomly splits symbols into 2, 3 or even 4 matching symbols: this increases your chances of creating a winning cluster.
When a winning cluster is formed, the winning symbols are removed from the grid, with new symbols dropping in to fill the empty grid positions. These new symbols can become ClusterBreaker symbols, leading to more splits. Symbols that have already been split will not be split again.
Multiplier Wheel
With the Multiplier Wheel starting at 1x, the multiplier doubles each time a winning cluster is formed. Applying to the win before doubling, the multiplier can double up to 1024x.
Coin Caper Bonus

The Coin Caper Bonus feature is triggered by landing 5 Coin symbols anywhere on the grid. Beginning with 3 respins, every new Coin symbol that lands resets the respins tally back to 3.
When 5 or more Coins connect, they combine into a single high-value Coin, creating space for more drops. Every cluster of 5 Coins increases the multiplier ladder, doubling with each step up to 1024x. Also, Mr Midnight Jr targets unbroken Coins, splitting them into 2, 3 or 4 of the same value for bigger Coin clusters.
Brute Force
All winning symbols are collected and added to the Smash ‘N’ Gran Free Spins meter: Collecting 20 symbols will trigger the Brute Force feature: this causes a cluster break of between 5 and 8 unbroken symbols (converting them into 2, 3 or 4 of the same kind).
Collecting 40 symbols causes a cluster break of all remaining unbroken symbols (and converting them into 2, 3 or 4 of the same kind).
Smash ‘N’ Grab Free Spins

The Smash ‘N’ Grab Free Spins feature is triggered by collecting 60 symbols in a single spin. Beginning with 8 free spins and a multiplier of 8x, the multiplier can double (up to 1024x).
You can also gamble to increase the starting multiplier as well as winning 1 extra free spin for every successful gamble. Successive gambles can lead to a 256x starting multiplier plus a total of 13 free spins. If you lose a gamble, you’ll revert back to the base game.
Once in, winning clusters double the multiplier, up to 1024x. On each new free spin, the multiplier reverts to the starting multiplier. Collecting 20 or 40 symbols will trigger stage 1 or 2 of the Brute Force feature whilst collecting 60 symbols retriggers the Smash ‘N’ Grab Free Spins feature.
SuperCharge, Bonus Buy & Enhanced Spins
As with other Relax slots like Guitar Quest, there are several SuperCharge, Bonus Buy and Enhanced Spins options:
- Bonus Reels: costing 10 x bet, regulay symbols are removed, leacing only Bonus symbols. Landing 2, 3 or 4 Bonus symbols will trigger the Smash ‘N’ Grab Free Spins feature with 8 free spins with a 8x multiplier, 9 free spins with a 16x multiplier or 10 free spins with a 32x multiplier.
- 16x Midnight Spins: costing 30 x bet, you get 1 spin with a 16x starting multiplier. Collecting 60 symbols awards an extra spin.
- 64x Midnight Spins: costing 90 x bet, you get 1 spin with a 64x starting multiplier. Collecting 60 symbols awards an extra spin.
- 256x Midnight Spins: costing 240 x bet, you get 1 spin with a 256x starting multiplier. Collecting 60 symbols awards an extra spin.
- Coin Caper Bonus: costing 80 x bet, you trigger the Coin Caper Bonus feature.
- 8x Smash ‘N’ Grab Free Spins: costing 80 x bet, you play the free spins with 8 free spins and an 8x starting multiplier (you can also gamble for a higher multiplier and more free spins).
- 32x Smash ‘N’ Grab Free Spins: costing 320 x bet, you play the free spins with 10 free spins and a 32x starting multiplier (you can also gamble for a higher multiplier and more free spins).
- 128x Smash ‘N’ Grab Free Spins: costing 1,280 x bet, you play the free spins with 12 free spins and a 128x starting multiplier (you can also gamble for a higher multiplier and more free spins).
- Enhanced Spins: costing 2 x bet, you increase your chances of triggering the Smash ‘N’ Grab Free Spins feature.
Verdict

Midnight Marauder ClusterBreaker is a high-energy slot with splitting symbols, Coin collections, multipliers up to 1024x and free spins with a higher starting multiplier for up to 10,000 x bet max win potential.
The Midnight Marauder ClusterBreaker slot is a friendly crime caper that introduces a ClusterBreaker mechanic: with symbols randomly splitting into 2, 3 or 4 matching symbols, the chances of forming winning clusters increases as, theoretically, 256 symbols can appear.
It does remind me of Big Time Gaming’s Megaclusters mechanic found in games such as Star Clusters Megaclusters. I would also recommend playing on a laptop or PC as the symbols are quite small, once split, on smartphones.
When it comes to the bonus features, the Coin Caper Bonus feature allows you to build up Coins but the ClusterBreaker mechanic needs to work its magic to win anything substantial. It works like Slotmill’s Coin Cluster feature found in Lucy Luck and the Quest for Coins and Coin Quest 2.
The Brute Force can see up unbroken symbols split which increases your chances of forming winning clusters. I found the Multiplier Wheel feature to be the most important as forming consecutive wins can see the multiplier rise, up to 1024x.
Then you have Smash ‘N’ Grab Free Spins feature where you can gamble to begin with 13 free spins and a 256x starting multiplier. The higher the starting multiplier, the quicker you can reach the top of the multiplier ladder essentially.
With 10,000 x bet max wins, the win potential is lower than the games mentioned but Midnight Marauder ClusterBreaker manages to combine various mechanics and features into an entertaining proposition that’s worthy of cracking the vault for.
