King of Slots is a royal-themed 5-reel slot from NetEnt that focuses on straightforward gameplay and a powerful Sticky Wins mechanic. While it may look basic at first glance, its fast pace and bonus features put it alongside other well-known NetEnt releases such as Starburst.
King of Slots Look and Feel
King of Slots has a clean and minimal presentation built around a classic 5×3 reel layout. The interface is simple, with crisp visuals and a colour palette built around royal blues and purples against a darker background.
At the centre of the theme is a cartoon king character with a curly moustache and permanent grin. Aside from this playful figure, the design stays fairly restrained.
The soundtrack takes a slightly unexpected direction. Rather than orchestral or regal music, the slot uses a light jazz-style track alongside traditional reel sounds and short audio cues when wins land.

How to Play King of Slots
The slot uses 5 reels and 25 paylines. Winning combinations are formed by landing three or more matching symbols on a payline from left to right.
Although the design is simple, the game includes several mechanics that keep gameplay interesting. The most important is the Sticky Wins feature, which can trigger when you land three or more matching symbols on a payline.
When this happens, the winning symbols stay locked in place while the remaining reels respin. If additional wins appear, the process repeats, giving you a chance to build multiple payouts from a single spin.
Players can adjust their stake using the controls on the interface before spinning the reels. The source also mentions optional features such as autoplay and turbo play, although availability may depend on where the game is played.
King of Slots Bonus Features
Free Spins
The Free Spins feature is triggered when five or more ruby Scatter symbols land anywhere on the reels.
The number of free spins awarded depends on how many scatters appear:
-
5 scatters – 10 free spins
-
6 scatters – 15 free spins
-
7 scatters – 20 free spins
-
8 scatters – 25 free spins
-
9 or more scatters – 30 free spins
During the feature, all wins are multiplied by 3x. The Sticky Wins mechanic also remains active, which can help extend winning combinations across multiple spins. Free spins can also be retriggered if additional scatters appear.
Sticky Wins
Sticky Wins activate whenever a spin produces three or more matching symbols on a payline.
The winning symbols remain locked in place while the other reels spin again without any additional cost. If new winning combinations appear, those symbols also stick and another respin occurs.
This chain continues until a respin produces no new wins, potentially filling large portions of the grid with winning symbols.
King of Slots Symbols
High-paying symbols:
The highest-paying symbol is the king’s crown, which awards the largest payout when five land on a payline. The watermelon fruit symbol also offers one of the stronger base-game payouts.
Medium-paying symbols:
Golden fruit symbols including cherries and lemons sit in the mid-range of the paytable.
Low-paying symbols:
The lowest-paying symbols are the card ranks: 10, Jack, Queen and Ace.
Wild:
The Wild symbol appears as a large blue emerald. It substitutes for most regular symbols to help complete winning combinations but does not award payouts on its own.
Scatter:
The Scatter symbol is represented by three rubies. Landing five or more anywhere on the reels triggers the Free Spins feature.
King of Slots Real-Money vs. Free Demo
Trying King of Slots in demo mode (available in certain jurisdictions only) can be a useful way to understand how the Sticky Wins mechanic works before playing for real money. Because this feature drives most of the action, getting familiar with how the respins build can help you judge the slot’s pace.
If you decide to play with real money, the combination of Sticky Wins and multiplier free spins offers the main potential for larger payouts.
Final Thoughts
King of Slots may not be the most visually advanced slot in the NetEnt catalogue, but it proves that simple mechanics can still deliver entertaining gameplay.
The Sticky Wins feature is the highlight, offering the chance to turn a single spin into a chain of respins and payouts. Add in multiplier free spins and a strong RTP, and the game delivers a solid experience despite its minimalist design.
If you enjoy classic slot structures with a twist, King of Slots is still worth a spin.
