1King Slot Catalogue: Providers, Bonus Link, Free Spin Selection
The 1King slot catalogue brings dozens of studios together in one place. Category icons at the top let you narrow the list by provider, theme, or play style. Below you'll find the providers that stand out, how the welcome bonus connects to slots, and how the Free Spin seçimi mechanic works.
As of 2026 the catalogue keeps getting new additions, so the category menu grows along with it.
Providers Worth Knowing
Among the roughly 63 providers in the catalogue, a handful come up especially often:
- Pragmatic Play — one of the largest studios in the industry, known for a broad catalogue and frequent releases; Gates of Olympus 1000, the game used in the welcome bonus, belongs to this provider.
- NetEnt — a long-standing studio known for classic and video slots.
- EGT Digital — recognised for high-volatility, classic-themed slots.
- Playson — a mid-sized studio with a wide, varied catalogue.
- Hacksaw Gaming — known for inventive mechanics and high-volatility titles.
- Red Tiger — recognised for cluster-pay mechanics and colourful visual style.
- BGaming — known for crypto-friendly infrastructure.
- Endorphina — a Europe-based studio focused on original themes and mechanics.
Beyond these names, niche studios such as Amusnet, Evoplay, Spinomenal, Habanero, Yggdrasil, Betsoft, Nolimit City, SmartSoft, GameArt, Spribe, Relax, TaDa, FAZI, and Fugaso also appear in the catalogue. The full provider list can be filtered from the category menu.
A second tier of the catalogue brings in studios that get less attention but are still part of the list: 3 Oaks, Amigo, True Labs, DreamPlay, 1Spin4Win, Fired Up Games, RubyPlay, Tap King, Netgame, Mrslotty, Inbet, Mancala, Belatra, Mascot, Gamzix, Barbarabang, Elbet, Spadegaming, Golden Race, Dragon Gaming, Netgaming, TopSpin, Swintt, KA Gaming, Champion, Mechanico, GameBeat, Gamomat, TomHorn, Golden Hero Group, Givme, and OneTouch. The mix ranges from studios that push out a high volume of titles to smaller, boutique developers built around a single theme or mechanic; typing any of these names into the provider filter pulls up that studio's full lineup in one row.
Having large and niche studios side by side makes it easy to move between play styles from a single platform — from familiar titles to lesser-known mechanics worth trying.
Why NetEnt Stands Out
NetEnt is a provider missing from some platforms entirely, so its presence in the 1King slot catalogue is worth noting. It's a solid pick for players who prefer the classic and video slot format, and a concrete sign of how broad the library is.
How the Welcome Bonus Ties Into Slots
The free spins from the first deposit are used on Gates of Olympus 1000 — the clearest link between the welcome package and the slot catalogue. The full four-deposit structure and rates are covered separately; see the bonuses page for the details.
Free Spin Selection
One of the standout features on the slots side is Free Spin seçimi. It lets you choose the spin size of the free spin package you've earned, rather than receiving a fixed amount. It's an uncommon option on most platforms, giving players direct control over how their free spins play out.
The mechanic isn't limited to the welcome package — the same selection logic can show up in other periodic promotions too.
Wagering Contribution on Slots
When bonus wagering is calculated, slots count 100% of the wagered stake by default. Some games may be excluded or carry a different contribution rate; the full list is published separately once you're logged into your account. There's no single published wagering multiplier — each promotion's own terms appear when you claim it.
Browsing by Provider
The provider rows beneath the category icons are the quickest way to find a specific studio. Each row lists that studio's games with small cover thumbnails, so you don't have to scroll the whole catalogue. If you want to try something less familiar, scrolling further down the provider rows surfaces studios you might not have picked otherwise.
What's Inside the Game Library
The 1King game library isn't limited to one slot format. Classic three-reel setups sit next to multi-reel video slots, cluster-pay structures, and high-volatility titles, all reachable from the same category menu. That range means a player looking for steady, low-risk spins and a player chasing high-volatility swings can both find something on the same platform.
Slots on the platform run on RNG (random number generator) technology, meaning every spin is generated independently and isn't affected by the result before it — a standard mechanism that applies across the entire catalogue.
Live Casino Is a Separate Section
This page focuses on the slot catalogue only. If you want to see the Turkish-themed roulette and blackjack tables, head to the homepage for the live casino section. Slots and live casino share the same balance.
If you don't have an account yet, you'll need to register first, or sign in via the login page if you already do — the slot catalogue opens up after that step.
