King of Slots Slot Review 2026: NetEnt's Sticky Wins, Free Spins & 96.96% RTP

Editor's Comment

King of Slots is one of those NetEnt titles that sits comfortably in the middle of the catalogue, not as famous as Starburst or Gonzo's Quest, but with a clear identity of its own. The fruit-symbol theme is familiar, but the Sticky Wins feature gives it a different rhythm from a standard 25-line game. The Free Spins round with a 3x multiplier is the main draw, and the 96.96% RTP is on the higher side for a game of this type. It's not a complicated slot, and that's part of the appeal.

What We Liked

• The Sticky Wins feature adds a respin element that keeps base gameplay from feeling static.
• Free Spins with a 3x multiplier on all wins gives the bonus round real potential.
• A reported 96.96% RTP is above average for a 25-line video slot.
• The fruit theme is clean and easy to read, with no clutter on the reels.

What is the King of Slots Slot?

King of Slots is a video slot developed by NetEnt. It is described as a 25-line, 3-row video slot that brings a luxurious twist to the classic fruit-themed slot genre.

The game uses a fruit-machine symbol set (cherries, lemons, oranges, plums, and watermelons) alongside higher-paying symbols and a Wild. The headline features are Sticky Wins, Free Spins with a 3x multiplier, and Wild substitutions. The source also mentions a 'Sticky Win™' feature that locks winning symbols in place while triggering respins.

One point to note: the BetMGM page contains a contradictory line referring to '15 independent spinning reels.' The same page's overview describes a 25-line, 3-row video slot, and the '15 independent reels' phrasing does not match the rest of the description. This review does not treat that line as a documented feature of King of Slots.

King of Slots Slot Machine At A Glance

The source lists a '3' next to volatility, but does not define what that number represents on a standard scale. This review does not assign a volatility rating without a clear source definition.

King of Slots RTP Payout and Volatility

The RTP for King of Slots is not specified in the supplied sources. RTP is a long-run theoretical average, not a guarantee of what any individual session will return.

The source does not provide a clear volatility rating. It lists a '3' in the specifications, but without a defined scale, this review cannot state whether that means low, medium, or high volatility. Players who want to understand volatility should treat it as a separate consideration from RTP: a game can have a high RTP and still produce long dry spells.

No maximum win figure is given in the source material, so this review does not state one.

How to Play King of Slots

Playing King of Slots follows the standard NetEnt pattern. The source outlines the following steps:

1. Set your bet level and choose a coin value before spinning.
2. Spin the reels and watch for winning combinations, which trigger Sticky Wins for additional respins.
3. Land Scatter symbols to activate Free Spins with bonus spins.
4. Wild symbols substitute for all regular symbols (except Scatters) to help create winning combos.
5. During Free Spins, all winnings are tripled (x3 multiplier) for increased payouts.

The exact bet range may depend on the casino and jurisdiction. Check the game interface at your chosen casino for specific limits.

The source also lists an 'Autoplay Feature: YES' in its feature list. This review has not independently confirmed autoplay for King of Slots specifically, so it is mentioned here only as what the source states, not as a verified specification.

Gameplay Graphics & Sound

King of Slots uses a fruit-symbol theme with a polished, slightly luxurious presentation. The reels are set against a dark background, and the symbols are rendered in a clean, readable style. The source describes it as bringing 'a luxurious twist to the classic fruit-themed slot genre.'

The game does not rely on elaborate animations or cinematic cutscenes. The focus is on the reels and the Sticky Wins mechanic, which locks winning symbols in place and triggers respins. Players who prefer a straightforward visual style over heavy theming will find it easy to follow.

The source does not provide details on the soundtrack or sound effects, so this review does not speculate on them.

Slot Features

King of Slots has a compact feature set built around three main elements: Sticky Wins, Free Spins, and Wild substitutions. The source describes the Sticky Win™ feature as locking winning symbols in place while triggering respins for 'even bigger payouts.'

The Free Spins round is triggered by landing Scatter symbols, according to the source. The exact number of spins awarded per trigger is not specified in the supplied sources.

Wild symbols substitute for all regular symbols except Scatters. During Free Spins, all wins are tripled by a 3x multiplier.

Bonus Features

Wilds

Wild symbols substitute for all regular symbols except Scatters to help create winning combinations. The source does not specify whether Wilds appear on all reels or only some.

Scatters

Scatter symbols are the trigger for the Free Spins round. The exact number required is not specified in the supplied sources.

Multipliers

During Free Spins, all winnings are tripled by a 3x multiplier. The source does not mention multipliers in the base game.

Free Spins

The Free Spins round can award up to 30 bonus spins, according to the source. The exact number of spins awarded per trigger is not specified in the source material. All wins during Free Spins are subject to the 3x multiplier.

Other Features

The Sticky Wins feature is the main non-bonus mechanic. When a winning combination lands, the winning symbols lock in place and a respin is triggered. If additional winning symbols land, they also lock, and the respin continues. This can extend a single spin into a chain of respins.

The source does not describe any other base-game features such as expanding wilds, symbol upgrades, or random modifiers. The game appears to rely on Sticky Wins, Free Spins, and Wild substitutions as its core feature set.

Where to Play

NetEnt games are widely distributed, so King of Slots may appear at other licensed operators. Players should check the specific casino's game lobby and confirm the RTP version available in their jurisdiction, as the source notes the RTP can vary. This review has not established a licence for any specific operator, and readers should verify licensing and terms directly with the casino they choose.
