Casino Fairness & Security

Fairness in an online casino is a narrower idea than it first sounds. It does not mean players win, and it does not mean a session comes out even. It means that nothing decides the outcome except the game's own random process, that the rules governing that process are published rather than hidden, and that nobody has the ability to reach into a round and change it once it has started.

That leads to a practical division of labour. Lunaris does not build the games it offers, and it does not host the random number generators behind them. The studios build the games, set the paytables, run the game servers and publish the fairness documentation. Lunaris presents the library, takes the bet, settles the result against your balance and keeps the round record. Understanding that split is the simplest way to see who to ask about what, and what fairness can and cannot promise you.

One thing this page does not do is make claims about certification or audits of Lunaris itself. What follows describes how outcomes are produced, where the numbers come from and what to do if a round looks wrong.

The games in the casino library come from established studios rather than from Lunaris. Partner studios include Pragmatic Play, NetEnt, Betsoft, Evolution Gaming and BGaming, and the live-casino section also features tables from Fresh Deck Studios and Visionary iGaming. Each studio develops its own titles, sets their mathematics, operates the servers that produce results, and publishes its own documentation on how its games behave.

That is worth knowing for a simple reason: when a question is about a game, the answer usually belongs to the studio, and the game itself is where the studio's answer is published. When a question is about your account, your balance or a settled bet, the answer belongs to Lunaris and support can trace it. The current list of studios live on the platform is on the providers page.

Most of the library runs on a random number generator. The generator is a source of unpredictable numbers running continuously on the provider's game server. When you press spin or deal, the game takes the value available at that microsecond and maps it onto its outcome space using a fixed table built into the game's maths model. The paytable then determines what that outcome pays for your stake.

Three consequences follow, and they are the ones players most often ask about.

• The result exists before the animation. By the time reels start turning, the outcome has already been produced and returned with a round ID. The spin animation reveals a decision; it does not make one.
• Every round is independent. The generator has no memory of your session, your balance or your losing streak. A game that has not paid in 200 spins has exactly the same probability on spin 201 as it had on spin one.
• Your stake does not change the odds. Bet size scales what a result pays, not which result appears.

The full mechanism, including how a number becomes a reel stop and why no spin is ever due, is covered in our guide to random number generators.

Return to player is the theoretical percentage of all wagers a game is designed to return over a very large number of rounds. A slot with a 96% RTP is built to return roughly $96 for every $100 wagered across millions of spins. It is a long-run average, not a forecast of your session, and it does not tell you what will happen in the next hundred rounds. Volatility, sometimes called variance, describes the shape of those returns: low volatility games tend to pay smaller amounts more often, high volatility games pay less often with the potential for larger results.

Both figures are properties of the game as the provider built it. Lunaris does not invent, set or adjust them. That is why the reliable place to check a title's RTP and volatility is the game's own information screen, usually reached from a menu or an "i" icon inside the game, rather than a third-party list that may be out of date or describing a different configuration of the same title.

• RTP is fixed by the game's maths model and paytable, not by the casino.
• Volatility describes how returns are distributed, not how much they total.
• Neither figure predicts a session. Both describe behaviour over a number of rounds far larger than anyone plays.

Our guide to what RTP means works through the arithmetic and the misconceptions that surround it.

Live dealer tables work on a different principle from RNG games: there is no random number generator involved at all. The outcome comes from physical equipment — a real shoe of cards, a real roulette wheel — handled by a dealer in a studio and streamed to you in real time. Table software reads the result from the physical equipment using card scanning and wheel sensors, and settles the round.

Fairness in this format rests on what you can see. The deal happens on camera, in one continuous stream, in front of every player at the table simultaneously. Multiple camera angles, visible card values and the dealer's own procedure are the audit trail, and the same round is watched by everyone seated. Live tables at Lunaris come from studios including Evolution Gaming, Fresh Deck Studios and Visionary iGaming, and can be found in the live casino section.

The differences between the two formats — pace, table limits, how results are produced and what you can verify — are set out in live casino versus RNG games.

Some crypto-native titles, such as crash and dice games and a number of BGaming releases, add a further layer called provably fair. It lets you verify a specific round yourself rather than relying on anyone's assurance.

The mechanism is a cryptographic commitment. Before you bet, the provider generates a secret server seed and publishes a hash of it. A hash is a one-way fingerprint: the same input always produces the same output, and the output cannot be reversed to recover the input. You supply or accept a client seed, which the provider did not know when it generated the server seed, and a nonce counts the rounds. The game combines those inputs through a published formula to produce the result. Afterwards, or when you rotate your seed pair, the provider reveals the original server seed.

• Server seed — the provider's secret value, hidden during play and revealed afterwards.
• Client seed — your input, which stops the provider from selecting a seed to suit a bet it has not seen.
• Hash commitment — published before the bet, so the seed cannot be swapped afterwards.
• Verification — hash the revealed seed, confirm it matches what was published, then re-run the formula to reproduce the outcome.

If the operator had changed anything, the revealed seed would hash to a different fingerprint and the mismatch would be immediate. Note what this proves and what it does not: it proves the result predated your bet and was not altered, not that the game is generous. The house edge is unchanged by verification. Where a title offers it, the seeds and hashes live in the game's own fairness panel, so verification happens there rather than through the casino. The full walkthrough is in what provably fair means.

Every round is logged with a round record, which is why a dispute is resolved by reference rather than by recollection. If a round looks wrong, contact support through live chat, available 24/7, or email [[email protected]](mailto:[email protected]) with:

• The game or round number
• The bet amount
• The date and time
• The game name
• The provider

The more information you provide, the faster the round can be located and checked. Contact routes for support, verification and banking queries are listed on the contact page, and the FAQ answers the cashier and account questions that come up alongside game issues.

Bonus terms are part of fairness too, because a promotion that can be claimed repeatedly by the same person stops being a promotion for everyone else. The rules that apply at Lunaris are set out in the terms and conditions, and the main ones are these.

• One per person. Promotions and bonuses are limited to one per person, household, email address, device, IP address or payment method, and only one Welcome Bonus per household or IP address.
• No stacking. Bonus stacking is not permitted, and real cash must be used before bonus funds.
• Wagering requirements. Unless a promotion states otherwise, bonuses carry a 20x wagering requirement calculated on deposit plus bonus, and bonuses are sticky: the bonus amount itself is not withdrawable and is removed during withdrawal approval.
• A contribution table applies. Different game types contribute differently to wagering — non-progressive slots contribute in full, while table games, video poker and live games contribute at lower rates.
• Abuse voids the bonus. Creating multiple accounts to claim bonuses, or attempting to manipulate a promotion, results in removal of the bonus and any associated winnings.
• Live casino is excluded. Bonuses are not offered for live-casino games.

Access to some studios' games through a VPN is not something Lunaris controls. Neither Pragmatic Play nor Evolution Gaming publishes a universal policy that clearly permits or prohibits VPN use in every country. Whether their games load depends on your location or the location your VPN connects through, the casino, and applicable regulatory requirements: some players reach these games through a VPN and others find access restricted.

Lunaris does not guarantee access to Pragmatic Play, Evolution Gaming or any other studio's games through a VPN, and cannot advise on bypassing geographic or regulatory restrictions. You are responsible for complying with the laws that apply where you are, and with the terms of both Lunaris and the game provider. If you do use a VPN, disable it before making a deposit or requesting a payout to avoid problems with the transaction.

Fairness also has a limit worth stating plainly: a random game that pays what it was designed to pay is still a game with a built-in margin, and no amount of verification changes that. Play only with money you can afford to lose.
