Fender & Bender ClusterBreaker Slot Review
A hydraulic press leans out of the shadows, a crushed car sits on the shop floor, and a battered yellow robot dangles overhead on exposed joints. This is the workshop Relax Gaming has built Fender & Bender ClusterBreaker in, and the theme isn’t decoration: this is a game about taking symbols apart and arguing over the repair bill.
It runs on a 5×5 cluster-pays grid with tumbling reels, a 96.10% RTP and a 15,000x maximum win. The switch is the whole point: Fender mode adds your activated multipliers together, Bender mode multiplies them, and the paytable never changes in between. Neither Midnight Marauder ClusterBreaker nor the Temple Tumble Megaways line ever let you set your own maths like this.
Cluster Pays and the ClusterBreaker Mechanic
There are no paylines here. A win needs five or more matching symbols adjacent horizontally or vertically, and winning clusters are removed so the symbols above tumble into the gap. New symbols drop in from the top, and the process repeats for as long as clusters keep forming.
The ClusterBreaker mechanic is active on every spin, cascades included. Symbols that haven’t yet been broken can be randomly split into two, three or four matching symbols, which makes reaching that five-symbol minimum considerably easier. Once a symbol has been broken, it can’t be broken again.
Any in-play symbol except Bonus symbols and Multipliers can be split. The wild substitutes for all regular paying symbols except the bonus symbol, which helps finish clusters that are one symbol short.
Pays are multiples of the total bet, scaling with cluster size:
- Foreman helmet (red tile): 20 symbols pays 10x, 17 to 19 pays 5x, 14 to 16 pays 2.5x, 11 to 13 pays 2x, 8 to 10 pays 1x, 5 to 7 pays 0.5x
- Red vehicle and green gears diamond: 20 pays 5x, 17 to 19 pays 2.5x, 14 to 16 pays 2x, 11 to 13 pays 1.5x, 8 to 10 pays 0.8x, 5 to 7 pays 0.4x
- Yellow worker sign and blue electric triangle: 20 pays 2.5x, 17 to 19 pays 2x, 14 to 16 pays 1.5x, 11 to 13 pays 1x, 8 to 10 pays 0.5x, 5 to 7 pays 0.2x
- Four coloured wrench gears (red, green, yellow, blue): 20 pays 2x, 17 to 19 pays 1.5x, 14 to 16 pays 1x, 11 to 13 pays 0.5x, 8 to 10 pays 0.2x, 5 to 7 pays 0.1x
Multiplier symbols also land on the reels, sitting dormant until one of the two mechanics presses the red button on the reel frame. Values run from x2 up to x50, and every activated multiplier is collected and applied to the win total at the end of the spin.
Fender and Bender Game Modes
The game’s central choice is a volatility switch. In Fender mode, every activated multiplier is added together before being applied to the win. In Bender mode, activated multipliers are multiplied together, so a x5 and a x4 become a x20 rather than a x9.
The mode can be switched at the end of any spin. Additive multipliers compound slowly and pay out more evenly; multiplicative ones spike hard and do most of their work rarely. Neither mode touches the paytable or the RTP, only the shape of the wins.
Free Spins: The Fender, Bender and Super Bonuses
Three bonus rounds share one trigger family. Landing three Bonus symbols on reels 2, 3 and 4 awards 10 free spins of either the Fender Bonus or the Bender Bonus, depending on the active mode.
Landing Bonus symbols on reels 2 and 4 with the Super Bonus symbol on reel 3 triggers the Fender & Bender Super Bonus, also worth 10 free spins. Each round runs a progressive multiplier that applies to every win. In the Fender Bonus, activated multipliers are added to the progressive total; in the Bender Bonus, they multiply it.
The Super Bonus runs both at once: Fender multipliers are collected and added first, then Bender multipliers are applied to the total. Landing three Bonus symbols during any of these rounds retriggers 5 free spins. Bonus symbols only land on reels 2, 3 and 4, and the Super Bonus symbol is restricted to reel 3.
Coin Respin Bonus and the Max Win Cash Ladder
Landing five coins anywhere on the reels triggers the Coin Respin Bonus. Triggering coins stay locked in place and the round begins with three lives. Each new coin that lands resets lives to three, and three consecutive spins without a coin ends the bonus.
When five or more coins connect, they merge into a single coin carrying their combined value, freeing space for more to land. The ClusterBreaker can split single coins into matching copies, and coin values run from 1x up to 10x. Multiplier symbols act as wilds for coin clusters, carry their own one-to-three lives, and multiply every coin in a cluster they join.
The Max Win Cash Ladder can fire at the end of any base game spin carrying between one and four coins, but the trigger is random and never guaranteed. When it does, the collected coin values plus any ClusterBreaker win from that spin are carried to the ladder.
It starts at 11x and climbs in steps of 11x: 22x, 33x, 44x, all the way through 99x and on to the top. The climb can stop on any rung, and reaching the top pays the game’s maximum 15,000x the bet.
Buy Feature, Supercharge and Enhanced Spins
The buy menu is unusually deep, and four of the direct buys run at 96.50% RTP, slightly above the base game’s 96.10%:
- Fender Bonus Buy: 150x the bet for 10 free spins
- Bender Bonus Buy: 150x the bet for 10 free spins
- Fender & Bender Super Bonus Buy: 500x the bet for 10 free spins
- Coin Respin Bonus Buy: 100x the bet for 3 lives
- Buy Mystery Bonus: 150x the bet, guaranteed one of six rewards at 96.10% RTP
The Mystery Bonus is an elimination draw: all six prizes are shown, five are removed one by one, and whichever remains is paid. The six are the Fender Bonus, the Bender Bonus, the Super Bonus, the Coin Respin Bonus and two cash prizes.
Three paid spin modes sit alongside the buys, all at 96.10% RTP. Mega Spins cost 250x the bet per spin for a single spin with both mechanics active, a guaranteed multiplier for each, and only the Super Bonus able to trigger. Max Win Cash Ladder Spins cost 1000x per spin and guarantee one to four coins land, sending every spin’s total to the ladder.
Bonus Reels cost 10x per spin, strip the paying symbols and leave only Bonus symbols, with a raised bonus entry chance. The Enhanced Spin option triples the base bet to improve the odds of triggering every feature and bonus, and it can’t run at the same time as the Supercharge modes.
Our Honest Verdict
Overall Rating: 7.9/10
Every spin is a near-miss by design. The splitter can turn any unbroken symbol into the missing piece of a cluster, so even losing spins look busy, and that’s the reason somebody picks this over a straight cluster game: you’re always one break away from a tumble chain.
The strength is that the mode choice is real rather than cosmetic. Same paytable, same features, genuinely different shape of wins: Fender pays steadily, Bender saves everything for rare spikes. The weakness is the Max Win Cash Ladder, the flabbiest idea in the shop. It fires at random, gives you no say in anything, and its 1000x buy is the steepest price on the menu for the least control.
It’s built for tinkerers, the sort who liked Midnight Marauder‘s take on the splitter and want more dials to turn. Anyone after one clean bonus round will find the shelves overstocked. Fender and Bender are both worth the hourly rate; just know which one you’re hiring before you lift the hood.
Fender & Bender ClusterBreaker FAQs
-
How do you trigger the free spins in Fender & Bender ClusterBreaker?
Free spins need Bonus symbols on the middle three reels: three of them anywhere on reels 2, 3 and 4 awards 10 spins of the Fender Bonus or the Bender Bonus, matching whichever mode is active. The Super Bonus swap-in lands the same way, with the Super Bonus symbol sitting on reel 3 between Bonus symbols on reels 2 and 4, and is also worth 10 spins. -
What is the difference between Fender mode and Bender mode?
Fender mode adds all activated multipliers together before applying them to a win, producing steadier payouts. Bender mode multiplies activated multipliers together, which produces rarer but much larger boosts. You can switch between the two at the end of any spin. -
Can the free spins retrigger in Fender & Bender ClusterBreaker?
Yes. Landing three Bonus symbols during any of the free spins rounds adds 5 free spins to the remaining total. No cap on retriggers is stated. -
What is the RTP of Fender & Bender ClusterBreaker?
The theoretical return to player is 96.10%. The four direct bonus buys run at 96.50%, and the Mystery Bonus, Mega Spins, Cash Ladder Spins, Bonus Reels and Enhanced Spins all run at 96.10%. -
How does the Max Win Cash Ladder work?
It can fire at the end of a base game spin carrying between one and four coins, but the trigger is random and never guaranteed. Coin values and any ClusterBreaker win are taken to a ladder that starts at 11x and climbs in steps of 11x. The climb can stop at any point, and the top rung awards the full 15,000x. -
How many paylines does Fender & Bender ClusterBreaker have?
None. Wins are cluster pays: a winning cluster is five or more matching symbols adjacent to each other horizontally or vertically on the 5×5 grid. -
What is the maximum win on Fender & Bender ClusterBreaker?
15,000 times the regular bet. If a win exceeds that amount, the round stops and 15,000x the normal bet is awarded. The top rung of the Max Win Cash Ladder pays it. -
When is Fender & Bender ClusterBreaker released?
Fender & Bender ClusterBreaker’s release date is 15 December 2026. It’s made by Relax Gaming.
