An online casino and a game provider are two different businesses. The operator runs your account, your cashier, the lobby and the promotions. It does not normally build the games. Those come from independent studios that design the title, write the mathematics behind it, produce the art and sound, and then license the finished game to operators. When you open a slot, you are loading that studio's software inside the casino's page.

That separation has two practical consequences. First, the outcome of a round is produced by the provider's game server, not by the operator, so a casino cannot alter a paytable or a published return. It is the reason a game you know from another site plays by exactly the same rules here. Second, the numbers that describe a game — its return to player, its volatility rating, its maximum win — are published by the studio and shown in the game's own info screen. Reading them there is more reliable than reading them anywhere else.

Studios also have recognisable identities. One specialises in cinematic slots with elaborate bonus rounds; another in fast, mobile-first rounds; another in dealt tables streamed from a studio floor with a human dealer. Learning whose games you enjoy is one of the more useful shortcuts in a lobby of over a thousand titles.

Each page below explains who the studio is, what it builds and how its games behave, and carries a live grid of that studio's titles at Lunaris.

• Betsoft — a slot developer working since 2006, known for cinematic 3D presentation and story-driven bonus rounds through its Slots3 collection.
• BGaming — a slot studio whose catalogue mixes conventional reel games with provably fair titles and fast, casual formats.
• Caleta Gaming — a Brazilian studio building mobile-first games, including bingo formats alongside its slots.
• Mancala Gaming — a developer producing slots and casual casino formats with a streamlined, modern presentation.
• Fresh Deck Studios — a live dealer supplier running streamed blackjack, roulette and baccarat tables with human dealers.
• Visionary iGaming — a live dealer supplier established in 2008, known for its blackjack tables and the Early Payout format.
• Pragmatic Play — a multi-product studio covering video slots, live casino and other formats, behind titles such as Sweet Bonanza and Gates of Olympus and the Drops & Wins network promotion.
• Evolution — a live casino specialist whose portfolio covers classic tables and game show formats, including the Lightning series.
• NetEnt — a Swedish slot developer active since the 1990s and the studio behind long-running titles such as Starburst and Gonzo's Quest.
• DRGT Gaming — a games supplier whose titles appear in the Lunaris lobby; the live grid on its page shows what it currently provides.

The pages are descriptive rather than ranked. No studio is presented as better than another, because the right one depends on whether you want long feature-driven slot sessions, short mobile rounds, or a dealt table with a person on camera.

The list splits into categories that answer different questions.

Slot and RNG studios build games where a random number generator decides the outcome — reels, paytables, free spins and bonus rounds. For these, what matters is the feature design, the published return and the volatility of a given title. How online slots work and what is an RNG cover the machinery.

Live dealer suppliers run physical tables in broadcast studios and stream them. Here the questions change: which tables are open, what the bet limits are, which side bets a table offers, and what the specific rules of that table are. See what is a live dealer casino and live casino vs RNG games.

Crash and fast-round formats sit apart from both: a multiplier climbs and you decide when to cash out, with rounds resolving in seconds. What are crash games explains the format.

One rule cuts across all three at Lunaris: bonuses are not offered for live casino games, and the bonus contribution table counts non-progressive slots at 100%, video poker at 20%, RNG blackjack and roulette at 10%, and live games at 1%.

There are three routes, and they suit different moments.

1. Start from a provider page. If you already know whose games you want, open that studio's page from the list above. The grid there is generated from the live catalogue, so it shows what is available right now rather than a list written months ago.
2. Filter the lobby. The full game lobby can be filtered by provider, as can the slot library and the live dealer lobby. This is the better route when you want to compare studios side by side within one game type.
3. Search by name. The lobby search box accepts a studio name as well as a game title, which is the quickest option on mobile.

Availability is not fixed. Studios release and retire titles, and operators adjust which parts of a catalogue they carry, so a provider's line-up changes over time. Where a studio's games depend on your location, the provider page says so. To play at Lunaris you must be 21 or over, or the legal gambling age in your jurisdiction if that is higher.

Two guides make everything on a provider page meaningful. What is RTP explains the long-run return percentage every studio publishes for its titles, and what is slot volatility explains why two games with the same return can feel completely different to play. With those two in hand, a description of a studio's maths reads as information rather than marketing.

From there, how online slots work covers reels, paylines and bonus triggers; what is a live dealer casino covers studios, cameras and card reading; and the casino glossary collects the vocabulary used across all of these pages. The full guides library has the rest.
