Vermin King
demo and specs

Vermin King is a video slot from Pragmatic Play with a release date of 22 October 2026. It pairs a 96.50% RTP with high volatility and a top prize of 1,598x your stake.

The name and the feature list point to a vermin theme. The three named features are the Vermin King feature, Pest symbol accumulation and Multipliers. Together they suggest a game where pest symbols build up and multipliers do the heavy lifting on the bigger results.

Vermin King pairs a 96.50% RTP with a 1,598x ceiling and high volatility.

It is aimed at players who are comfortable with high volatility and who prefer a feature-led game to a steady drip of small wins. If you like watching a mechanic build towards a payoff, the accumulation theme is the draw.

On what is published: the studio has given the RTP, the volatility grade, the max win and the feature names. Grid size, payline count, stake range and hit rate are not published, so this page does not guess at them.

The RTP is 96.50%, which sits half a percentage point above the rough 96% UK average. Over a very long run, the theoretical house edge is £3.50 per £100 staked, against £4 at an average-RTP slot. That is a small edge in your favour compared with the norm. It is a long-run average across millions of spins, not a promise about any one session.

Volatility is graded High. In practice that means returns tend to arrive in fewer, larger chunks, with longer stretches where the balance drifts down between them. A session can finish well below or well above the RTP figure, and the swings are wider than on a low-volatility game.

The max win is 1,598x stake. The studio has not published the stake range, so the minimum and maximum bets are not on file here. Instead, here is the ceiling worked at illustrative stakes:

• At a £0.20 stake, 1,598x comes to £319.60
• At a £1 stake, 1,598x comes to £1,598
• At a £10 stake, 1,598x comes to £15,980
• At a £100 stake, 1,598x comes to £159,800

For a high-volatility game, 1,598x is a fairly modest cap. It means the volatility is not being paid for with an enormous top prize, so most of the risk is in the dry spells rather than in chasing a headline jackpot.

No hit rate is published for Vermin King, so there is no studio figure to quote. What can be said is that a High volatility grade normally goes with a lower hit frequency, meaning more spins that return nothing and bigger payouts when the features land.

The studio lists three features for Vermin King. Here is what each is and how that category of mechanic generally behaves:

• Vermin King feature: the headline bonus. Features named after a slot's lead character usually act as the main bonus round, where the bigger wins are concentrated.
• Pest symbol accumulation: pest symbols are collected over time rather than just landing and vanishing. Accumulation mechanics generally build towards a threshold or a payoff, so progress matters.
• Multipliers: values that scale a win by a set factor. They are usually most valuable when they combine with a strong base result or sit inside a bonus round.

The studio has not published the trigger for the Vermin King feature, how many pest symbols are needed, how the accumulation resets, the multiplier values or how they combine. The page is updated when Pragmatic Play publishes them.

No bonus buy is listed among the features. In any case, buying a bonus or feature directly is switched off for GB players at UKGC casinos, as the regulator's rules do not allow that kind of purchase for UK customers. Any UK bonus round has to be reached through normal play.

The grid size and payline count are not published, so the exact layout is not stated here. What the feature list suggests is a base game that exists mainly to feed the accumulation and multiplier mechanics, with the bigger results sitting in the features.

The stake range is also unpublished. Whatever the limits turn out to be, the approach at this volatility is the same. A smaller stake stretches a bankroll through the dry spells and gives the accumulation mechanic more spins to play out. A larger stake raises the cash value of every win, including the 1,598x ceiling, but shortens the time you can sit through a cold run.

As a rule of thumb for a High volatility game, set a session budget you can afford to lose before you start, and size the stake so the budget covers a long stretch of spins rather than a handful. Treat any win as a bonus, not as income.

Pragmatic Play builds its slots for mobile as standard, so a phone is a normal way to play. The UK rules apply on a phone exactly as on desktop: no autoplay-style shortcuts that break the rules, and the standard spin-speed and reality-check requirements of a UKGC casino.

Among accumulation and multiplier slots, Vermin King sits at the riskier end on volatility but at the lower end on ceiling. Many high-volatility games in this mechanic group chase a much bigger top prize to justify the dry spells. Vermin King caps out at 1,598x, so the trade is different.

What that ceiling buys is a slot where the risk is front-loaded into the waiting rather than into a long-shot jackpot. A lower cap tends to make the features easier to reach in relative terms, though the studio has not published the figures to confirm how much easier.

The RTP of 96.50% is a point in its favour. It is above the rough UK average, so the long-run cost of playing is a little lower than at a typical slot. Set against a bigger-ceiling rival, it is the steadier of the high-volatility options, but it is not a steady game in absolute terms.

The similar-slots table that follows carries the real comparison figures, so use that rather than this section for a numbers-first side-by-side.

Vermin King suits these kinds of player:

• Players who like accumulation mechanics and enjoy watching a feature build towards a payoff
• Players who accept high volatility but would rather not rely on a six-figure-multiplier long shot
• Players who want a slightly above-average RTP of 96.50% and plan to play on a fixed, modest budget
• Anyone who wants to try the real game on play money first, since a free demo runs the full game with no deposit

Skip it if you want frequent small wins to keep a balance steady, if you are after the biggest possible top prize, or if you need every spec such as the grid, paylines and stake range confirmed before you play. Those details are not yet published.
