Slayers Inc slot review

Slayers Inc slot at a glance

Slayers Inc comes from Hacksaw Gaming, the Malta-based studio behind Wanted Dead or a Wild, and it follows the studio’s familiar recipe: a compact line-based game, a high ceiling and a base game that can go quiet for long stretches. The table below sets out the published specification. Anything not listed here, such as the exact grid size or symbol values, varies in how listings describe it, so open the game’s help screen for those details.

Two numbers deserve the most attention before you press spin. The first is the RTP version the casino has chosen, which we cover below. The second is volatility: a high-volatility slot with a 15,000x top prize pays a large share of its return through rare, big results, so most short sessions end below the starting balance. That is normal behaviour for this type of game, not a sign that anything is wrong. Our guide to slot volatility explains the trade-off in more depth.

How the features work in Slayers Inc

The headline mechanic is DuelReels, a Hacksaw design that has turned up across several of its recent games. In Slayers Inc, two multipliers duel, and the result of that contest sets the multiplier for the reel it happens on. In plain terms, a reel can become worth more than its symbols alone, and the duel decides by how much.

Hacksaw’s launch notes for other DuelReels titles describe the general pattern: a VS symbol that lands as part of a win expands to cover its whole reel, two characters face off, and the winner’s multiplier is applied to that reel. You can read that description in Hacksaw’s Eternal Duel announcement (opens in a new tab). Slayers Inc’s own paytable is the place to confirm how its version triggers, which multipliers can appear and whether several duelling reels combine, because these details change from game to game. Eternal Duel, for example, runs from 2x to 100x, while other DuelReels games use different ranges.

Why does this matter for your money? A reel multiplier works on top of the line win it touches. A small payline win that happens to pass through a duelling reel can turn into a sizeable one, while a spin without a duel pays only the base line value. That concentration of value in occasional events is a large part of why the game is rated high volatility. Our page on DuelReels compares how the mechanic differs across Hacksaw titles, and the multipliers guide explains how multipliers change the shape of a slot’s payouts.

Since a Gambling Commission warning in January 2020, feature buy-ins are not offered to British players, so in the UK the bonus content in Slayers Inc has to be reached through normal spins.

What a reel multiplier does to a Slayers Inc win

The arithmetic is simple even if the game hides it behind animation. A multiplier multiplies the win it applies to. The figures in this table are made up purely to show the sum; they are not values taken from the game, so check the paytable for the real ones.

Read the last row carefully. The same multiplier is worth four times as much when it lands on a stronger line win, which is why big results tend to need two things at once: a decent symbol combination and a large reel multiplier. Neither is under your control, and the random number generator decides each spin independently of the last.

Slayers Inc RTP: which of the four versions are you playing?

Hacksaw supplies Slayers Inc in four RTP settings, and each casino picks one. The house edge is simply 100% minus the RTP, and the expected cost of a spin is the stake multiplied by that edge. Here is what the choice means at a 50p stake.

The lowest setting costs about 3.2 times as much as the highest for exactly the same game, graphics and features. These are long-run averages over a very large number of spins, so any single session can land far above or below them, but the averages are what you pay for over time. UK rules require the RTP to be available to players, usually inside the game’s information or help screen, and our page on UK RTP information rules shows where to look. The question of why the same slot has different RTPs at different casinos has its own explainer too.

How the 14 paylines pay in Slayers Inc

Slayers Inc pays on 14 fixed paylines. A win needs matching symbols in a row along one of those set paths, usually starting from the leftmost reel. Your total stake is spread across all 14 lines, so you can’t switch lines off to save money, and the paytable shows each symbol’s value as a multiple of the total bet.

A line game with a small number of lines behaves differently from a ‘pays anywhere’ grid or a Megaways game. With 14 lines, many spins produce nothing at all, and the game relies on special features rather than frequent small hits to deliver its return. Compare that with ways to win slots, where any matching symbols on adjacent reels count. Neither format is better value in itself; the RTP decides the long-run price.

A £20 budget on the Slayers Inc slot at 10p, 50p and £1

Here is how a £20 budget stretches at three stakes, assuming the 96.28% version. ‘Spins from £20’ counts how many spins £20 buys if nothing were won back, which is a fair way to picture how fast a high-volatility game can run through a balance.

At 10p, wins are recycled through many more spins, so the session tends to last longer and the result drifts closer to the average. At £1, twenty losing spins would empty the budget, and on a high-volatility slot runs of that length are common. The expected cost per spin rises in proportion to the stake, so tripling or quadrupling your bet raises your hourly cost by the same factor. Our session budget calculator lets you test other stakes, and the guide to making a budget last covers practical habits.

Slayers Inc max win: 15,000x stake in pounds

The top prize is 15,000 times the stake. The cap is a ceiling the game will stop at, not a target it aims for, and reaching it is extremely rare. This table turns it into pounds.

A high cap tends to come with a thin base game, because a share of the RTP is set aside for the rare top-end results. Our explainer on what a max win cap means covers how the cap works if a feature would otherwise pay more.

Slayers Inc against other Hacksaw Gaming slots

Hacksaw’s catalogue is full of games with similar numbers, so it helps to line them up. All figures are the developers’ published top versions.

The top RTPs sit within a few hundredths of a percentage point of each other, so in practice the version a casino offers matters far more than which of these games you pick. If you prefer a gentler ride, our list of low volatility slots is a better starting point than anything in this table.

How to play Slayers Inc online

1. Sign in at a UKGC-licensed casino and set a deposit limit before you play; you’ll be prompted to set a financial limit before your first deposit.
2. Open Slayers Inc and go straight to the help or information screen to check the RTP version and the DuelReels rules.
3. Choose your stake with the bet buttons; the game won’t let you exceed £5 a spin, or £2 if you’re aged 18 to 24.
4. Press spin. Each spin takes at least 2.5 seconds, and you need to press again for the next one because autoplay isn’t allowed.
5. Watch the on-screen net position and time played, and stop when you reach the limit you set, win or lose.

If you want to understand the mechanics before staking anything, some casinos offer a demo mode, but UK rules mean you still need to verify your age first. The explainer on whether you can play slots for free in the UK explains how that works.

UK rules that shape how Slayers Inc plays

British versions of Slayers Inc follow the Gambling Commission’s design and stake rules, so the game can look a little different from footage filmed elsewhere.

• Stake limits: £5 a spin for players aged 25 and over since 9 April 2025, and £2 for 18–24s since 21 May 2025, per the Commission’s online slots stake limit guidance (opens in a new tab). See our page on slot stake limits.
• No autoplay, no turbo or slam-stop, and at least 2.5 seconds per spin, under rules in force since 31 October 2021.
• No celebration sounds or graphics for a return that is no more than your stake.
• No bonus buy: feature buy-ins have not been offered to British players since a Commission warning in January 2020.

None of these rules changes the RTP. They change the speed and size of play, which in turn changes how much an hour costs. The full background is on our game design rules page.
