King of Slots

King of Slots is a five reel NetEnt slot with a regal theme and the studio's Sticky Win re-spin feature, and it is a familiar classic for Irish players looking for a dependable NetEnt title to enjoy in euro. Released in 2015, it keeps the layout deliberately simple so the appeal comes from stringing wins together rather than working through a crowded feature set. If you prefer frequent, smaller payouts to rare big swings, it makes for a relaxed session.

How King of Slots plays

The grid is five reels and three rows with 25 fixed paylines, so every spin covers the same lines and you only adjust your stake. The blue sapphire is the Wild and substitutes for every symbol except the Scatter, helping you complete lines. The signature mechanic is Sticky Win: when a winning combination lands, those symbols lock in place while the other reels re-spin. If the re-spin adds a matching symbol or a new combination, the new symbols also lock and you get another re-spin, continuing until nothing new appears. Five or more Scatters trigger the free spins round, where line wins are multiplied and the feature can be retriggered.

King of Slots RTP, volatility and max win

King of Slots has a published RTP of 96.96%, close to the NetEnt average. It is rated low volatility, which means wins tend to arrive frequently but in modest amounts, so your balance moves in small steps rather than through long dry runs interrupted by rare spikes. The maximum win is 700x your total stake, a realistic ceiling for a low variance slot built around Sticky Win chains rather than one enormous payout. Looking at RTP and volatility before you play is a good habit for any game.

Playing King of Slots in Ireland

Ireland's Gambling Regulatory Authority (GRAI) is standing up a domestic licensing regime through 2025 and 2026. For now, Irish players typically use casinos licensed by well regarded EU regulators such as the Malta Gaming Authority, with balances and bets in euro. The casinos listed on this page offer King of Slots, and the free demo above needs no account and no deposit, so you can get a feel for the Sticky Win feature before playing for real money.

Is King of Slots worth playing?

King of Slots is worth trying if you want a straightforward, low volatility NetEnt slot with an engaging re-spin hook and a clean 25 line layout. It will not suit players chasing very high multipliers, but for relaxed sessions it works well. Set a budget before you start and treat any wins as a bonus, and if gambling stops being enjoyable, read the guidance on responsible gambling.
