Casino glossary

A single wager that combines multiple selections; every pick must win for the bet to pay. The odds multiply together, so potential returns are higher than separate singles, but the risk rises because one losing leg loses the whole bet.

A publisher or partner that sends traffic to an operator and may earn commission when users sign up or play. Affiliates must follow advertising and disclosure rules so readers know relationships may exist.

A forced bet posted before cards are dealt in some table games (notably poker) to seed the pot. In broader usage it can mean any upfront stake required to participate in a hand or round.

A long‑term bet placed before the final declarations or field is confirmed—common in horse racing for festivals or big races. Prices can be attractive, but rules differ if your selection does not run; always check non‑runner terms.

A slots feature that repeats spins automatically with preset stakes and limits. Regulators in many markets restrict or require safer controls (loss limits, mandatory pauses) because autoplay can speed up play.

A comparing card game where you bet on whether the Player hand, Banker hand, or a tie will win, aiming for a total closest to nine. It is known for simple rules and a relatively low house edge on Banker/Player bets.

The total amount of money you have set aside for gambling after essential expenses. Managing bankroll size, bet sizing, and loss limits is core to playing within your means.

A card game where you try to beat the dealer by getting closer to 21 without busting. Basic strategy and rule variations (dealer on soft 17, doubling rules, payouts for blackjack) change the house edge.

Behaviour operators view as exploiting promotions against their intent—such as coordinated accounts, minimal‑risk betting patterns purely to clear wagering, or duplicate claims. It can lead to voided bonuses and closed accounts.

A feature in some video slots letting you pay a multiple of your stake to enter the bonus round immediately. It increases cost per spin dramatically and is restricted or banned in certain jurisdictions.

A promotional code entered at sign‑up or deposit to unlock an offer. If required, missing the code often means you cannot claim that specific deal later, so read the landing terms carefully.

A football market that pays if each side scores at least once during the match (usually 90 minutes plus injury time unless stated otherwise). It ignores who wins the match.

The amount you pay to enter a game or tournament and receive chips or credits. In poker it is the entry stake; in live casino game shows it may mean the cost to participate in a round.

After a win, winning symbols disappear and new symbols drop in, allowing chain reactions from one paid spin. It is also called tumbling reels, avalanche, or similar branding by different studios.

Settling an open bet early for a return offered by the bookmaker, which may be more or less than your eventual outcome. Availability, partial cash out, and pricing are at the operator’s discretion.

A promotion that refunds a percentage of net losses or turnover over a period, often as cash or bonus funds with its own rules. Check whether cashback is real money, how often it credits, and any caps.

A major four‑day National Hunt racing festival in March in the UK, hugely popular with Irish fans and punters. Markets include championship races, antepost prices, and specials; liquidity and promotions spike that week.

A slot payout mechanic where wins come from clusters of matching adjacent symbols rather than fixed paylines. Larger clusters typically pay more and may trigger features.

A short voluntary break from gambling on an account—hours to days—where you cannot bet but can usually still withdraw. It is lighter than self‑exclusion and is meant to interrupt impulsive play.

An operator or product set that accepts crypto (e.g. Bitcoin) for deposits or gameplay, often alongside fiat. You still need to check licensing, volatility, wallet security, and whether bonuses apply to crypto deposits.

A cap you set on how much you can deposit over a day, week, or month. Licensed sites must offer deposit limits in many markets; lowering them often takes effect quickly, while increases may be delayed.

A football market covering two of the three match outcomes (for example home or draw). The odds are lower than a single result because your coverage is wider.

In blackjack, doubling your bet after the first two cards in exchange for exactly one more card. Rules on when doubling is allowed vary by table and affect optimal strategy.

A market where the draw refunds the stake; you win only if your chosen side wins. Odds are shorter than a straight win bet because you get money back on a tie.

An online wallet (such as PayPal, Skrill, or Neteller) used to move funds to and from betting accounts quickly. Some bonuses exclude e‑wallet deposits, so read offer terms before you choose a method.

Two bets in one on racing: part on the horse to win and part on it to place at a fraction of the win odds. Place terms (e.g. top three, 1/4 odds) depend on the race and field size.

Roulette with a single zero on the wheel (37 pockets). The absence of a second zero lowers the house edge compared with American double‑zero roulette.

Complimentary spins on selected slots, usually at a fixed line bet. Winnings may be cash, bonus funds, or capped; wagering requirements and expiry dates are common.

Betting on Gaelic Athletic Association sports such as Gaelic football and hurling, including match odds, handicaps, and outright championships. Availability and depth of markets vary by bookmaker.

An optional mini‑risk game after a win (e.g. guess the card colour) that can multiply or lose the win. It increases variance and is disabled in some regulated markets.

Rules that count only a percentage of stakes on certain games toward bonus wagering. Slots often count 100%, while low‑risk table bets may count far less or be excluded.

Official authorisation from a regulator for an operator to offer gambling services in a jurisdiction. A visible licence number, complaints process, and adherence to local law are baseline trust signals.

A market where a notional advantage or deficit is applied to balance the teams—common in football (Asian/European handicaps) and US spread betting. The handicap changes how your side must perform for the bet to win.

A brand or VIP programme oriented to large‑stake players, often with higher table limits, faster withdrawals, and personal hosts. Terms still apply; bigger stakes mean faster bankroll swings.

How often a game produces any winning outcome, not how big those wins are. High hit frequency can still pair with low overall RTP or many small wins that do not cover your stake.

The share of money wagered that the house retains over time in a given period or machine. It is related to RTP and actual player behaviour; it is not the same as theoretical RTP on a single session.

The built‑in statistical advantage for the operator expressed as a percentage of each bet the player should expect to lose long run. Lower house edge means slower expected losses for the same stakes.

Betting on an event after it has started, with odds that update live. Delays and suspensions protect against information advantages; stakes can be rejected if odds change before acceptance.

Identity and verification checks required by licensed operators (ID, address, source of funds when needed) to prevent fraud, underage gambling, and money laundering. Until completed, withdrawals may be blocked.

Betting against an outcome on an exchange—you act like the bookmaker and risk paying backers if that outcome occurs. Liability can exceed a normal stake, so exchanges show maximum loss clearly.

A major racecourse in Dublin hosting top National Hunt and Flat fixtures, including Christmas meetings and trials for Cheltenham. It is a staple of Irish racing betting markets.

Table games streamed from a studio or venue with real dealers, where you bet through an interface. Games include blackjack, roulette, baccarat, and show‑style games; latency and table limits vary.

A cap on how much you can lose in a period on a site, sometimes separate from deposit limits. It helps automatic shutdown when the threshold is hit.

A full cover bet with four selections: four singles, six doubles, four trebles, and one four‑fold (15 bets). Bookmakers often advertise bonuses if all four win or only one wins.

A method using free bets and covering the opposing outcome on an exchange to lock in value. It still requires capital, attention to rules, and tax or reporting awareness; mistakes can leave you exposed.

A promotional term limiting the stake per spin or hand while using bonus funds. Exceeding it can void the bonus and winnings, even if the software allowed the larger bet.

The highest amount a game round or feature can pay, set by rules or a prize cap. It can apply to base game, free spins, or jackpots; read paytable and casino limits together.

A licensed slot mechanic with changing ways to win per spin because reel heights vary. It typically uses cascading wins and can include tens of thousands of ways when reels expand fully.

The smallest amount you can transfer to trigger an account top‑up or sometimes to qualify for a bonus. It differs by method (card vs crypto) and currency.

Casino games and sportsbooks accessed on phones or tablets via browser or apps. Performance, geolocation requirements, and app store policies affect availability.

A feature that increases a win by a factor (e.g. x3). Multipliers may apply in base game, free spins, or bonus trails and can stack depending on rules.

A small offer credited without funding your account, intended to try the site. It almost always has wagering, max withdrawal caps, and eligible games—expect strict terms.

Marketing for operators that delay or minimise verification for small play. In practice, licensed sites usually require KYC before sizeable withdrawals; unlicensed “no KYC” venues carry major counterparty risk.

The price of a bet, expressing implied probability and return. Formats include fractional (common in Ireland/UK), decimal, and American; movement reflects liability and new information.

A bet on whether a statistic (goals, points, corners, etc.) finishes over or under a line the bookmaker sets. Tie rules on exact numbers matter—check whether stakes push or lose.

A sign‑in flow using bank identification for quick deposits and automatic account creation, pioneered by Trustly’s model in some EU markets. Not universally available in every country.

Predefined patterns across reels where matching symbols must land for a pay in classic slots. Ways‑to‑win and cluster games replace paylines with different geometry.

A processing window after you request a withdrawal before the casino sends funds, sometimes cancellable by player choice. Regulators may restrict reversal to protect players.

Gambling that causes harm to finances, relationships, or mental health, or loss of control. Support includes helplines, counselling, self‑exclusion registers, and treatment services.

A prize pool that grows with contributions from linked bets until it is won. Odds of winning the headline jackpot are low; check whether your stake size qualifies you for the top tier.

Ice hockey’s spread bet, usually ±1.5 goals, combined with moneyline‑style pricing. It adjusts for goal differential because NHL games are often close.

On‑screen reminders after a set playing time showing duration and sometimes stakes. Licensed sites often must offer reality checks you can configure.

A match or perk on deposits after your first welcome package, aimed at retaining players. Wagering, game restrictions, and expiry are similar to welcome offers—read caps on bet size and winnings.

Account features like deposit and loss limits, time reminders, timeouts, self‑exclusion, and reality checks. They are mandatory on many licences and work best when you set them before play.

Software that produces unpredictable outcomes for digital games, audited to statistical fairness standards. Live dealer games use physical cards and wheels instead of an RNG for main results.

The percentage of stakes a game is designed to return to players over a very long run; the remainder approximates house edge. It does not predict short‑term session results.

A symbol that pays or triggers features without needing to land on a single payline—often anywhere in view if enough appear. Rules define minimum counts and whether scatters pay cash.

Customer balances held separate from an operator’s business costs, per licence rules, to improve protection if the company fails. Segregation is not always the same as a statutory guarantee.

A formal block from gambling with an operator—or across a national scheme—for months to years. Breaking it by creating new accounts can cause account closures and refunds to be denied.

A limit on how long you can stay logged in or active before the site logs you out or warns you. It complements deposit limits for time‑based control.

In blackjack, dividing a paired starting hand into two hands for an extra bet equal to your first. Tables restrict which pairs you may split and how many times you can split.

TLS/SSL secures data between your browser and the casino site (padlock in the address bar). It prevents casual interception but does not replace checking for a real licence and fair terms.

The amount you risk on a bet. Total returns depend on stake multiplied by odds (plus each‑way or system bet maths where relevant).

A non‑withdrawable bonus that can be played and used to generate winnings, but the bonus principal is removed on withdrawal (only profit above the sticky amount may cash out in some models). Terms vary widely—verify definitions in the offer text.

Ireland’s flagship Flat racing venue in County Kildare, hosting Classics such as the Irish Derby and major Group races. It anchors Irish racing calendars and betting turnover.

One bet combining three selections; all three must win. It is a small accumulator format common on football coupons and racing multiples.

An extra login step (app code, SMS, hardware key) beyond your password. It substantially reduces account takeover risk where attackers guess or steal passwords.

A bet you believe has better implied probability than the true chance—i.e. the odds are “too big.” Finding value needs modelling or deep market knowledge; favourites can still be value.

Submitting documents or data so the operator can confirm identity, age, and payment ownership. Completing verification early avoids payout delays at withdrawal time.

How swingy payouts are: low volatility tends toward frequent smaller hits; high volatility can mean long dry spells and rare large wins. Volatility pairs with RTP but describes a different aspect of risk.

How many times bonus (sometimes deposit+bonus) must be wagered before withdrawals. Contributions differ by game; watch expiry dates and max bet rules.

A site run on a platform provider’s licence and technology, customised with a brand’s look and marketing. The operator of record for complaints is usually named in the footer terms.

A symbol that substitutes for others to complete wins according to the paytable. Variants include expanding, sticky, and multiplier wilds with their own rules.

Caps per transaction, day, week, or month on how much you can cash out. VIP status and jackpot wins may negotiate exceptions; progressive wins can have special rules.
