Casino Glossary

An auto cash-out is a setting in a crash game that closes your bet automatically at a multiplier you choose in advance, without you having to click during the round.

Crash rounds can end in well under a second, so setting the target before the round starts removes reaction time from the equation. It does not change the odds or the house edge — it only makes your intended exit point reliable. Read the crash games guide.

Autoplay is a slot setting that plays a set number of spins at your chosen stake without further clicks, usually with stop conditions such as a single-win threshold or a loss limit.

Autoplay changes nothing about the maths of the game; each spin is still resolved independently by the RNG. Its practical value is the stop conditions, which turn a loose intention into a limit the game enforces for you.

Baccarat is a card game in which you bet on which of two hands — Player or Banker — will finish closer to a total of nine, or on the two hands tying.

Players make no drawing decisions, because the third-card rules are fixed, which is why baccarat is fast and easy to learn. It is one of the most played live dealer games. Read the live baccarat guide or browse the live casino.

The Banker bet in baccarat is a wager that the Banker hand will win. It carries the lowest house edge of the main baccarat bets, and winning Banker bets are usually charged a 5% commission.

The commission exists precisely because the Banker hand wins slightly more often than the Player hand under the fixed drawing rules. Even after the commission, it remains mathematically stronger than the Tie bet.

Your bankroll is the total amount of money you have set aside for play — money you have decided in advance you can afford to lose.

Bankroll management means choosing a stake in proportion to that total and holding to it, rather than raising bets to chase a loss. It is the single habit that most affects how long a session lasts, and it matters more than any game choice.

Basic strategy is the mathematically optimal set of blackjack decisions — hit, stand, double or split — for every combination of your hand and the dealer's upcard.

It is derived from probability rather than intuition, and following it minimises the house edge for the rules you are playing. It does not turn blackjack into a winning game; it makes it the least expensive version of itself. Read the blackjack guides.

Bet limits are the minimum and maximum stakes a game or table accepts per round, set by the game provider and the casino.

Live tables display their limits in the lobby so you can pick one that suits your bankroll, while slots express the same idea as a stake range. Bonus terms often impose a separate, lower maximum bet while wagering is still active. Read the wagering requirements guide.

Bitcoin is the first and largest cryptocurrency, a digital asset transferred between wallet addresses and recorded on a public blockchain rather than moved through a bank.

At an online casino it functions as a deposit and withdrawal method: you send from your own wallet to an address the cashier generates. Its price moves against the dollar, so a balance held in BTC can change in fiat value. Read how Bitcoin casinos work.

Blackjack is a card game in which you aim to beat the dealer's hand without exceeding 21, using decisions such as hit, stand, double down and split.

It exists in two forms online: RNG blackjack, dealt by software, and live blackjack, dealt by a human on a streamed table. Rules vary by variant and directly affect the house edge. Read the live blackjack guide.

A blockchain is a shared public ledger that records transactions in linked blocks, maintained by a network of computers rather than by a single company.

Once a transaction is recorded and confirmed it cannot be quietly edited, which is why crypto deposits and withdrawals can be traced by anyone holding the transaction ID. Read what a crypto casino is.

A bonus is extra funds or spins a casino credits to your account under stated conditions, usually tied to a deposit and always attached to terms such as a wagering requirement.

A bonus is not free money in the everyday sense: it is a promotion with rules about which games count, how much you must wager and what you may withdraw. Read the terms before you claim one. Read how casino bonuses work.

A bonus buy, sometimes called a feature buy, is a slot option that lets you pay a fixed multiple of your stake to enter the bonus round immediately instead of waiting for it to trigger.

The price is set so the feature's expected return stays close to the game's base RTP. Buy features are not offered in every market or on every title, and bonus funds usually cannot be used for them.

A bonus code is a short string you enter in the cashier or in a promotion field to claim a specific offer.

Codes exist so a casino can target a promotion at a particular campaign or group of players rather than everyone. If an offer requires a code and you deposit without it, the bonus normally cannot be added afterwards, so enter it before confirming the deposit.

To cash out in a crash or similar multiplier game is to close your bet mid-round and take your stake multiplied by the value showing at that moment.

If the round crashes before you act, the stake is lost. The phrase is also used loosely to mean requesting a withdrawal, so read it in context. Read what crash games are.

The cashier is the section of your casino account where you deposit, request withdrawals, and view the payment methods and limits available to you.

At Lunaris it opens from the wallet icon with the plus symbol at the top right, with separate tabs for deposit and payout, and it is where your daily, weekly and monthly withdrawal limits are displayed.

The client seed is the part of a provably fair game's input that comes from your side — normally a string your browser generates, which you can change at any time.

Because the outcome depends on both the server seed and your client seed, changing yours demonstrates that the operator could not have known the complete input in advance. Read the provably fair guide.

Cluster pays is a slot mechanic that awards wins for groups of matching symbols touching horizontally or vertically anywhere on the grid, instead of along fixed paylines.

Winning clusters usually disappear and are replaced by new symbols dropping in, so a single spin can produce several chained wins. Read how online slots work.

A confirmation is the network's record that a crypto transaction has been included in a block. Every additional block adds another confirmation and makes the transaction harder to reverse.

Casinos wait for a set number of confirmations before crediting a deposit, which is why crypto deposits are not immediate. Lunaris requires 2 confirmations on the blockchain before funds appear in your balance. Read how to deposit Bitcoin.

The contribution rate is the percentage of a wager on a given game category that counts toward clearing a wagering requirement.

Slots typically contribute in full while table and live games contribute far less. The Lunaris contribution table is 100% for non-progressive slots, 20% for video poker, 10% for all RNG blackjack variations, 10% for roulette and 1% for live games. Read the wagering requirements guide.

A crash game is a fast, round-based game in which a multiplier climbs from 1x and stops — crashes — at a random point. You bet before the round starts and win your stake times the multiplier if you cash out before the crash.

Rounds last seconds, every player watches the same curve, and most crash titles publish a provably fair record for each round. Explore the crash games guides.

A crypto casino is an online casino that accepts cryptocurrency for deposits and withdrawals, either alongside cards and e-wallets or exclusively.

Using crypto changes the payment rails, not the games or the rules around them: identity checks, bonus terms and responsible gambling tools still apply in the same way. Read what a crypto casino is.

A deposit is money you transfer into your casino account so that it becomes a playable balance.

Minimums depend on the method. At Lunaris the minimum card deposit is $50, while crypto deposits start at $20 with no stated maximum and are credited once the required blockchain confirmations arrive. Browse the crypto guides.

Doubling down in blackjack means doubling your original stake in exchange for exactly one more card, after which your hand stands automatically.

The option is offered on your first two cards, and basic strategy limits it to hands where a single extra card is likely to leave you strong against the dealer's upcard, such as a total of eleven.

Ethereum is a blockchain network with its own cryptocurrency, ether, used both for payments and for running smart contracts.

Casinos that accept ETH treat it much like Bitcoin: you send from your wallet to a generated address and wait for confirmations. Network fees rise and fall with congestion. Read about Ethereum casinos.

Free spins are slot spins that do not deduct from your cash balance. They arrive either as a feature triggered inside a game or as a promotion the casino credits on selected titles.

Promotional free spins normally specify the eligible games, a fixed value per spin and a wagering requirement on anything you win from them. Read the free spins guide.

A game provider, or studio, is the company that designs, builds and certifies a casino game. The casino licenses and hosts the title but does not control its outcomes.

Providers publish the RTP and volatility of each game and submit their random number generators for independent testing, which is why the same title plays identically across different casinos. Browse the providers.

A hash is the fixed-length output of a one-way cryptographic function. The same input always produces the same hash, but the hash cannot be reversed to reveal the input.

Provably fair systems use exactly this property to commit to a result in advance: the game shows you the hash of the server seed before the round and reveals the seed afterwards, so you can check that the two match.

The house edge is the casino's built-in mathematical advantage on a game, expressed as the percentage of each wager it expects to retain over the long run.

House edge and RTP are two ends of the same figure and add up to 100%, so a 96% RTP game carries a 4% house edge. Both are long-run averages measured across enormous numbers of rounds. Read the house edge guide.

Insurance is a side bet offered in blackjack when the dealer shows an ace. It pays 2:1 if the dealer turns out to hold a natural blackjack.

Under normal rules it is priced against the player, so basic strategy declines it. The same reasoning applies to the "even money" offer made when you hold a blackjack against an ace, which is the identical bet in another form.

A jackpot is a top prize in a game, either a fixed amount tied to a specific winning combination or a pooled amount that grows with play.

Fixed jackpots are paid from the game's own paytable and are already accounted for in its published RTP. Pooled prizes behave differently — see progressive jackpot below.

KYC, short for Know Your Customer, is the identity verification a casino performs to confirm who you are, normally using a government photo ID and a proof of address.

It is a standard anti-fraud and anti-money-laundering step, usually completed before a first withdrawal. At Lunaris verification is completed within 24 hours in most cases, and documents are submitted to the verification address listed in the FAQ. Read about no-KYC claims.

Litecoin is a cryptocurrency derived from Bitcoin's design, with faster block times and typically lower transaction fees.

Those properties make it a common choice for smaller casino deposits and withdrawals. Lunaris lists BTC, ETH and LTC among the cryptocurrencies you can select in the cashier's crypto option.

A live dealer game is a real table run by a human dealer with physical cards, a wheel or dice, streamed to you in real time, with bets placed through an on-screen interface.

Outcomes come from the equipment rather than from an RNG, and the same table is shared by many players at once. Read what a live dealer casino is or compare it with RNG games.

A max bet rule is a cap on how much you may stake per round while bonus funds or bonus winnings are in play.

It exists to stop a wagering requirement being cleared in a handful of very large bets. Breaching it can void the bonus and the winnings attached to it, so check the figure in the promotion terms before increasing your stake.

A max cashout, or maximum withdrawal, is a cap written into a promotion's terms on how much of the winnings derived from a bonus you may withdraw.

Anything above the cap is removed when the withdrawal is processed. Lunaris notes that individual promotions may carry their own maximum cashout limits, so read the terms of the specific offer you claim.

Megaways is a licensed slot mechanic in which the number of symbols on each reel changes on every spin, producing a variable number of ways to win — often several hundred thousand at the top end.

Because the shape of the grid changes, wins are formed by matching symbols on adjacent reels rather than along fixed lines. Read how online slots work.

A multiplier increases a win by a stated factor: a 3x multiplier triples the payout it applies to.

Multipliers appear as symbols on the reels, as features inside slot bonus rounds, and as the central mechanic of crash games, where the entire round is a rising multiplier applied to your stake.

A network is the specific blockchain a crypto transfer travels on. Many assets exist on more than one network, and each has its own address format, fees and confirmation speed.

Choosing the wrong network is the most common and least recoverable crypto deposit mistake. Lunaris warns that sending funds on an incompatible network may result in the loss of those funds, so always match the network shown in the cashier. Read the deposit guide.

Paylines are the fixed patterns across a slot's reels on which matching symbols must land in order to pay.

Classic slots use a handful of lines; many modern titles replace them with ways-to-win, cluster or Megaways systems in which position on a line no longer matters. Your stake is normally divided across all active lines. Browse the slots guides.

A progressive jackpot is a prize that grows as players bet, funded by a small slice of every qualifying wager, and resets to a seed value once it is won.

Networked progressives pool contributions across many casinos, which is how they reach very large sums, and that pooled portion sits outside the game's base RTP. Read the progressive jackpots guide.

Provably fair is a cryptographic method, used mainly in crypto casino games, that lets you verify a round's result was determined before you bet and was not changed afterwards.

It works by combining a hashed server seed, your client seed and a round counter, then publishing the seed so you can recompute the outcome yourself. It proves a round was not tampered with; it does not remove the house edge. Read the provably fair guide.

A reload bonus is a deposit match offered to existing players rather than to new ones, usually at a lower percentage than a welcome offer.

It carries the same kind of terms: a qualifying deposit, a wagering requirement and a contribution table. Lunaris offers up to a 200% reload bonus for eligible returning players, and terms and conditions apply.

Responsible gambling is the set of tools and habits that keep play controlled and affordable, including deposit limits, loss limits, session reminders, time-outs and self-exclusion.

Casino games are designed to return less than they take over time, so gambling is entertainment with a cost rather than a source of income. Play only with money you can afford to lose, and only if you are 21 or over, or the legal gambling age in your jurisdiction if higher.

An RNG, or random number generator, is the software that determines the outcome of each round in a slot or an RNG table game, producing an independent and unpredictable result every time.

Because rounds are independent, a game cannot be hot, cold or due, and no pattern of timing or stake size affects it. Certified RNGs are tested by independent laboratories. Read the RNG guide.

Roulette is a wheel game in which you bet on where the ball will land. European wheels have 37 pockets with a single zero; American wheels have 38 because they add a double zero.

That extra pocket roughly doubles the house edge, from about 2.7% on European wheels to about 5.26% on American ones, which is why the European layout is generally the better choice. Read the roulette guides.

RTP, or return to player, is the theoretical percentage of all wagered money a game is designed to return to players over a very large number of rounds.

A 96% RTP slot pays back about $96 of every $100 staked when averaged across millions of spins. It is a long-run average across all players, never a session forecast, and it says nothing about how those returns are distributed. Read the RTP guide.

A scatter is a slot symbol that pays or triggers a feature — most often free spins — wherever it lands, without needing to sit on a payline.

Scatters are usually the trigger for a game's bonus round, with a set number of them required anywhere on the reels. The paytable states how many you need and what each combination awards.

Self-exclusion is a formal request to block your own access to an account or an operator for a fixed period or permanently, and it cannot normally be reversed before it expires.

It is the strongest of the responsible gambling tools and sits alongside softer options such as cooling-off periods and deposit limits. If gambling stops feeling like entertainment, use it.

The server seed is the secret value a provably fair game generates for a round or a series of rounds. Its hash is published before you bet and the seed itself is revealed afterwards.

Revealing it lets you confirm that the hash you were shown matches the seed actually used, which proves the result could not have been swapped after your bet was placed.

A side bet is an optional wager placed alongside the main bet on a table game, paying on a specific event such as a pair in blackjack or a tie in baccarat.

Side bets generally carry a noticeably higher house edge than the main game, so they cost more per dollar staked in exchange for larger but rarer payouts.

A stablecoin is a cryptocurrency designed to hold a steady value against a reference asset, most often the US dollar. USDT and USDC are common examples.

For a casino balance the appeal is predictability: a stablecoin deposit does not gain or lose fiat value while you play, unlike Bitcoin. Compare Bitcoin and USDT.

A sticky bonus is a bonus amount that stays in your balance for play but is never withdrawable itself; it is removed when a withdrawal is processed, leaving only the winnings it generated.

Lunaris states that unless otherwise stated all of its bonuses are sticky, and that the bonus amount is removed during the withdrawal approval process. Read how casino bonuses work.

USDT, commonly called Tether, is a stablecoin intended to track the value of the US dollar, and one of the most widely used digital assets for online payments.

It exists on several blockchains, so the network you choose determines the address format and the fee you pay. Check the cashier for the currencies and networks currently supported before sending anything.

Volatility, also called variance, describes how a game's payouts are distributed: how often it pays, and how large those payouts tend to be.

Low-volatility games pay smaller amounts frequently; high-volatility games pay rarely but larger. Volatility is independent of RTP, so two games with identical RTP can produce very different sessions. Read the volatility guide.

A wagering requirement, also called playthrough or rollover, is the total amount you must stake before winnings tied to a bonus can be withdrawn. It is written as a multiplier such as 20x.

At Lunaris the requirement is 20x, calculated on the deposit plus the bonus, so a $100 deposit with a $100 bonus means $4,000 in wagers, adjusted by the contribution table. Read the wagering requirements guide.

A wallet address is the string of characters identifying the destination of a crypto transfer, similar in role to an account number.

Casino cashiers generate a deposit address for you, and a new address is normally issued for each transaction. Copy it or scan the QR code rather than typing it out, and confirm the network matches. Read about crypto withdrawals.

A welcome bonus is a promotion for new players, most often a percentage match on a first deposit, subject to a wagering requirement and a maximum bonus amount.

Lunaris currently offers a 400% slots welcome match for new players, limited to one use, with a $100 minimum qualifying deposit, a maximum bonus of $100 and the standard 20x wagering requirement. Terms and conditions apply. Browse the casino.

A wild is a slot symbol that substitutes for other symbols to help complete a winning combination, though usually not for scatters or bonus symbols.

Variants include expanding wilds that fill a whole reel, sticky wilds that stay in place across respins, and wilds that carry a multiplier of their own. Browse the slots.
