The Slayers Inc slot is a 2024 Hacksaw Gaming ninja game on 14 paylines where VS symbols start DuelReels: two slayers each reveal a multiplier, they fight, and the winner’s multiplier is applied to a whole wild reel. The top RTP is 96.28%, volatility is high and the max win is 15,000× the stake. Here is the full breakdown.
A VS symbol expands into a wild reel whose multiplier is decided by a duel between two slayers.
Three, four or five scatters lead to three different bonus rounds, each stronger than the last.
The RTP ranges from 96.28% down to 88.22% depending on the version your casino chose.
15,000× the stake means £30,000 at the £2 limit for 18–24s and £75,000 at the £5 limit.

What is the Slayers Inc slot?
Slayers Inc is a Hacksaw Gaming slot released in 2024. The setting is a neon city of graffiti and ninja assassins, and the signature mechanic is DuelReels, a twist on the wild multiplier in which the multiplier on a wild reel is settled by an on-screen fight. Wins are paid on 14 fixed paylines from the leftmost reel.
Everything in the game builds on that duel. The base game shows occasional VS symbols, while the free spins rounds make them more frequent or add extra wilds. It’s a high-volatility title, so most of its return comes from a small share of spins. Browse the rest of the studio’s catalogue in our slots hub.
How DuelReels work on the Slayers Inc slot machine
DuelReels only switch on when a VS symbol can contribute to a win. When it does, the sequence is:
A VS symbol lands and expands to cover its whole reel.
Two slayers appear, each holding a multiplier value.
They duel, and one survives.
The surviving slayer’s multiplier is attached to the reel, and the reel becomes wild.
Wins that pass through the reel are multiplied by its value.
If two or more VS reels are part of the same win, their multipliers combine as set out in the game rules.
Published game guides give a multiplier range of 2× to 500×. As with any animated feature, the duel is presentation: the random number generator has already decided the outcome when you press spin.
A worked DuelReels example in pounds
Here is an illustrative spin at a £1 stake. Say three Oni masks on a line would normally pay 2× the stake, and a VS reel sits on reel 2 with a surviving multiplier of 10×.

Slayers Inc symbols and pay tiers
The low symbols are five coloured graffiti tags. Above them sit a shuriken and a skull, then a male and a female ninja, and at the top an Oni mask. Wins need three or more on a line from reel 1. Open the paytable at your chosen stake for exact cash values.

Slayers Inc free spins: three rounds by scatter count
The number of scatters that land together decides which bonus you get. Published game guides describe the ladder like this:
Slayers Inc bonus ladder (as published)
Scatters

What changes
3
Rise of the Syndicate
10 free spins with VS symbols more likely
4
Wild Slayers
10 free spins; a slicer can add a full row of wilds when a VS lands
5
One Slayer to Slay Them All
DuelReels and the slicer act on every spin
Extra scatters in the first two rounds add spins (free spins retriggers). The higher rounds are rarer, which is typical of a scatter ladder: each step up is worth more on average and appears less often.
The Best of Bonus: three rounds, one payout
A separate Best of Bonus symbol can land with the scatters. When it does, the round is played three times and you’re paid the single best result. In maths terms, you receive the maximum of three draws rather than one draw, which lifts the floor of a bonus without changing the game’s overall RTP, because the chance of the Best of version is already priced into the base game. It doesn’t add the three results together.
Slayers Inc RTP versions and session cost

Who the Slayers Inc slot suits
Advantages
Clear, readable mechanic: one duel, one multiplier, one wild reel
Three bonus tiers give variety
Top RTP of 96.28% when the casino runs that version
Drawbacks
High volatility: long dry spells are normal
Lower RTP versions are common and easy to miss
Combining rules for multipliers need reading before play
It suits adults who enjoy feature-led games and are comfortable with uneven results on a fixed budget. If you prefer frequent small wins, a medium volatility slot will feel steadier.
How the UK version of Slayers Inc differs
In some markets Slayers Inc sells enhanced feature spins and direct bonus entry. Versions supplied to UK-licensed casinos come without bonus buys, so in Britain each round must be reached through scatters. The usual UK design rules also apply: no autoplay since 31 October 2021, a 2.5-second minimum per spin, no turbo, and no celebration of returns at or below the stake (slot game design rules).
Many casinos offer the Slayers Inc demo as free demo play, after age verification; UK operators have had to verify age before demo play since May 2019 (age and ID verification (opens in a new tab)). In the demo, watch how often VS symbols land and how the multipliers combine. Then check the help screen for the RTP before playing for money, using how to find a slot’s RTP.

Frequently asked questions
What is the RTP of Slayers Inc?
The top RTP of Slayers Inc is 96.28%, and Hacksaw Gaming also supplies versions at 94.36%, 92.40% and 88.22%. Casinos choose which version to run, so the figure in the game rules is the one that counts. At 96.28%, 100 spins at £1 cost about £3.72 on average over the very long run; at 88.22% the same spins cost about £11.78. See RTP variants for how to spot the difference.
What is the Slayers Inc max win?
The Slayers Inc max win is 15,000× the stake. That works out at £1,500 on a 10p spin, £15,000 at £1 and £75,000 at the £5 limit for players aged 25 and over. Players aged 18–24 can stake up to £2 a spin online, so their maximum is £30,000. The game stops the round if the cap is reached. Read what slot has the biggest max win for comparison.
What are DuelReels in Slayers Inc?
DuelReels are the game’s main feature: a VS symbol expands over its reel, two slayers reveal multipliers and fight, and the survivor’s multiplier is applied to the reel, which turns wild. Published guides give a range of 2× to 500×. When several VS reels join one win, their multipliers combine according to the game rules. The result is set by the RNG before the animation. Our multipliers page explains the general idea.
How do you trigger free spins on Slayers Inc?
You trigger free spins on Slayers Inc by landing scatters: three lead to Rise of the Syndicate, four to Wild Slayers and five to One Slayer to Slay Them All. A Best of Bonus symbol landing with them plays the round three times and pays the best result. UK versions don’t sell bonus entry. Our page on what triggers a bonus round explains why triggers can’t be predicted.
What is the Best of Bonus in Slayers Inc?
The Best of Bonus is a version of the free spins round that is played three times, after which you’re paid only the highest of the three results. It appears when a special Best of symbol lands alongside the scatters. It makes a very poor bonus less likely, but it doesn’t change the overall RTP, which already allows for it. It is not three payouts added together. Compare bonus game formats in our glossary.
Is Slayers Inc a high volatility slot?
Yes, Slayers Inc is rated high volatility. A small share of spins, mainly those with high DuelReels multipliers and the stronger bonus rounds, carry much of the return, so many spins pay little. Budgets can run down quickly on unlucky sessions. Decide on a fixed amount before playing and stop when it’s gone. Our high volatility slot machines guide explains what to expect.
Can I play Slayers Inc for free?
Many casinos offer Slayers Inc as free demo play, after age verification. UK rules introduced in May 2019 mean you must confirm your age before playing any game, including demos. Demo credits have no cash value, but the demo is useful for seeing how often VS symbols appear and how the bonus ladder works. Our demo slots guide explains how to use demos sensibly.
How many paylines does Slayers Inc have?
Slayers Inc pays on 14 fixed paylines. A win needs three or more matching symbols on a line, starting from the leftmost reel. Lines can’t be reduced, so your stake always covers all 14. A VS reel turns wild and so connects to every line passing through it, which is why it can produce several multiplied wins on one spin. See our paylines explainer for more.
Who makes Slayers Inc?
Hacksaw Gaming makes Slayers Inc. The studio launched in September 2018, is headquartered in Malta and holds a Gambling Commission licence for Great Britain; its parent company has been listed on Nasdaq Stockholm since June 2025. Hacksaw is known for multi-tier bonuses and the Best of mechanic used here. Our Hacksaw Gaming provider page lists its other games.
Can you buy the bonus on Slayers Inc in the UK?
No. Some international versions of Slayers Inc sell feature spins and direct bonus entry, but slots supplied to UK-licensed casinos don’t include bonus buys. British players reach Rise of the Syndicate, Wild Slayers and the five-scatter round only through normal spins. Reviews quoting buy prices refer to other markets. See bonus buy in the UK for the background.
