SlimKing slots: around 4,200 games in the ring

Around 4,200 of SlimKing’s 5,000+ games are slots, so this is where most players will spend their time. The range is wide: sharp high-volatility titles from Hacksaw Gaming, Novomatic classics, Betsoft’s 3D games and a long tail of smaller studios. Our guide shows you how to find your way around.

Types of slots at SlimKing

Hacksaw Gaming headliners

Hacksaw is one of the stand-out studios in SlimKing’s lobby, with fighting-themed titles that suit the site’s boxing flavour. Fighter Pit and Fist of Destruction lean straight into combat themes, Le Bandit and Le Viking are popular picks with big top wins, and Stormforged and The Luxe round out the set. Le Viking is also the game for SlimKing’s weekly Sparring Spins.

Novomatic and Betsoft classics

Book of Ra Deluxe is the Novomatic favourite that carries the 200 welcome free spins, and Vault Lock Crack It Big adds a more modern Novomatic option. From Betsoft, At the Copa, Triple Cash or Crash and Pho Sho bring polished visuals and steady bonus features.

Blueprint, Penguin King and the rest

Blueprint Gaming’s Bankin’ More Bacon and Plenty O’Fish are familiar to UK players. Penguin King supplies Hold & Win games such as 3 Pyramids of Gold Hold & Win. Skywind’s Sunken Riches, Mascot’s Hot Fruit x15, Platipus’s Joker Chase and Gamzix’s Royal Chip cover lighter, quicker play. Further titles come from Evoplay, Gamomat, Peter & Sons, Popiplay, TrueLab, Fantasma, PG Games, ELA Games, 1spin4win and Onlyplay.

RTP and volatility explained

RTP (return to player) is the share of all money staked that a game pays back over the very long run. A 96% RTP slot returns £96 for every £100 staked across millions of spins, on average. At SlimKing most slots sit between 94% and 97%, and each game’s RTP is shown in its info panel.

Volatility describes how those returns arrive:

• Low volatility – frequent small wins, gentler swings. Classic fruit games often sit here.
• Medium volatility – a balance of regular wins and occasional bigger features.
• High volatility – long dry spells broken by rare large wins. Many Hacksaw titles fit this profile.

Neither number tells you what will happen in a single session. Pick volatility to match your budget: high-volatility games can burn through a small balance quickly.

UK rules on every spin

UK Gambling Commission rules shape how slots work for GB players, at SlimKing and every other UK-licensed casino:

• Stake limit: £5 per spin, or £2 per spin if you are aged 18–24. This also applies while wagering a bonus.
• No autoplay: you must press spin for every round.
• Minimum spin speed: each spin must take at least 2.5 seconds; turbo modes and slam stops that go faster are not allowed.
• No bonus buys: buying a feature is banned for GB players, so free spins and bonus rounds only trigger in normal play.
• Clear results: games may not celebrate a return smaller than your stake as if it were a win.

Slots and the SlimKing bonuses

Slots contribute 100% to the 10x wagering on the welcome bonus (200% up to £3,000 + 200 Free Spins), which makes them the quickest way to clear it. Jackpot slots are excluded. Slot play also earns points in the weekly Title Belt Tournaments, with a £10,000 prize pool. See the full rules on our wagering rules and promotions pages.
