Online casino glossary A — Z: over 90 terms you will encounter in terms (2026)

Online casino bonus terms and conditions are often full of terms that have entered Ireland's player vocabulary straight from English — wagering, RTP, scatter, free spins , KYC. When you add Ireland's own translation ("spin", "return", "scattered symbol"), the result is a dictionary of two languages ​​in one document. This dictionary sorts them alphabetically, explains in two to four sentences, and where it makes sense, adds an example in crowns and a link to a detailed article on our website.

Terms are sorted by Ireland name. If you see it in English in the game (paytable, bonus buy, RTP), you will find it in brackets after the term Ireland. For each concept, you will see an example as needed — how much it costs you to spin, what is the casino's mathematical advantage for the given game or what is the amount of the regular welcome bonus in Ireland casino. The dictionary is a living document — when casinos change conditions or introduce new mechanics (Megaways, Hold and Win, buying a bonus), we continuously add terms here.

AND

Action code (promo code, action coupon)

Bonus code tied to a specific campaign or partner. Ireland casinos use them especially when cooperating with comparators and editors — without a code, the promotional bonus is often not activated, even if the player is formally entitled to it. You can find the current codes for individual operators in the section bonuses .

AML

Abbreviation of English Anti-Money Laundering — countermeasures against money laundering. Ireland licensed casino is mandatory according to Act No. 253/2026 Coll. Verify player identity (KYC), verify sources of income for larger deposits and report suspicious transactions. It is AML that is behind why the casino can ask you for proof of the origin of the money (pay slip, tax return, sales contract) when making a withdrawal.

Example: after a deposit of € 5 and a request to withdraw € 20 the casino on its own initiative even as a preventive measure (within AML) it can request proof of the origin of the money before it processes the withdrawal.

Anti-fraud control

Internal casino system that looks for fraudulent behavior: multiple accounts from one IP address, use of a foreign payment card, bonus abuse (bonus abuse), automated play. In case of suspicious behavior, the account will be blocked and additional verification will be required. Detail in article on withheld withdrawals .

Automatic rotation (auto-play/autospin)

An automatic function that allows you to set 10 — 1,000 spins forward without the need for repeated clicking. An Ireland licensed operator is required to attach a stop-loss limit to the automatic rotation, so that the function will stop you when the agreed loss is reached. An activated stop-loss is therefore the most essential part of automatic rotation — without it, you lose track of your budget.

Example setting: 100 spins × €= budget €, stop-loss € 30. The game is on stops at €30 losses regardless of how many spins are left.

Aviator and crash games

A new kind of game, where after a bet, the plane (or other symbol) starts to rise — and the multiplier grows with it. The player must cash out in time before the plane "takes off" and the multiplier drops to zero. RTP 96 — 97%. In detail in of the Aviator article .

B

Baccarat

A table card game where you bet on a Player, Banker or Tie. The house's mathematical house edge is just 1.06% on a banker bet — among the lowest in the entire casino. The game is popular with higher stakes (high roller) for the low margin of the casino. Detail in separate article on baccarat .

Banker (Banker)

In baccarat, one of the two main betting positions. Colloquially, "banker" is also used for a croupier at full-pay tables. In technical terms, the banker in baccarat is a separate deck of cards that has nothing to do with the person behind the table.

Bank transfer (bank transfer)

The classic way of depositing and withdrawing via a payment order between accounts. Deposit via bank transfer takes one to two working days, withdrawal is the same. It is often the only option for larger amounts (above €5). Comparison in article on payment methods .

Blackjack

A card game where the goal is to get your cards as close to 21 as possible without going over. With an optimal basic strategy, the mathematical house edge is only 0.5% — the lowest among casino games. Comprehensive analysis in the article blackjack: basic strategy and in article about blackjack ireland .

Bonus

Any form of extra funds that the casino credits to your deposit or registration. The most common types: welcome bonus (for the first deposit), no deposit bonus (free), free spins, reload bonus , cashback, VIP bonus. Each bonus has a spin, a time limit and often a maximum bet. Always read the terms and conditions before accepting — it breaks down bonus mistakes separate article .

Bonus without deposit (no deposit bonus)

The bonus you get just for registering and verifying your account, without the need to deposit your own money. Ireland is most often 125 — €20 or 10 — 50 free spins. Spins are typically 30 — 50x, maximum win 1,250 — €. Details in the article no deposit bonus upon registration .

Bonus €10 with 40x spin= you have to reinvest €. At an RTP of 96% expected loss € 10. Real value of the bonus after spinning: roughly €. The no deposit bonus makes real sense mainly like "trying out" the casino without own money.

Bonus code (promo code)

The character string that you enter when registering or depositing to unlock a specific bonus. Ireland casinos use it mainly for exclusive offers for partners, news for regular players or tied campaigns. Without a code, the bonus is often not activated — even if you are eligible. After registration, you can enter the code of some casinos (Tipsport, Fortuna, Chance) without any problems additionally, others only during the first deposit.

Second deposit bonus

A bonus that the casino adds to your second deposit — typically as part of a welcome package split between two or three deposits. Ireland casinos most often offer it in the amount of 50 - 100% of the deposit, up to a ceiling of 2,500 - €. Spinning tends to be 30 — 35x.

C

Bonus time limit

The time you have to spin the bonus. After it expires, the bonus and all winnings resulting from it will be forfeited. Ireland casinos usually set 7, 14 or 30 days. With welcome bonuses with high spins (60 — 70x), the time limit is one of the most common bottlenecks — the player does not have time to spin within a reasonable budget. Practical examples in article on the value of bonus conditions .

Cashback

A bonus in which the casino returns a percentage of the net loss for a given time. Typically 5 - 25% of the loss per week. Cashback is most often tied to 1 — 5x spins, sometimes it is completely unconditional (pure cash, immediately available). With high losses, it is one of the most advantageous types of bonuses — it does not involve the risk of a new deposit, it only mitigates your loss.

Example: during the week you lose €, the casino offers a cashback of 15% without spins = € 30 back to your player account, for immediate withdrawal.

Cluster pays

A winning mechanic in which a group (cluster) of the same symbols adjacent horizontally and vertically — without winning lines — forms a win. Typically 5 — 8 or more symbols of the same kind. Famous games: Sweet Bonanza, Reactoonz, Sugar Rush. It is often combined with the "tumble" mechanic, in which winning symbols disappear and new ones fall from above.

Craps

A dice table game that is rather marginal in Ireland online casinos but available in a live casino (Evolution). Mathematical casino advantage 1.4 — 1.6% on basic bets on "pass line" and "don't pass line". Analysis in the article craps in an online casino .

D

Tax on winnings

Winnings from Ireland licensed casinos are exempt from personal income tax (up to a limit) under current legislation. Therefore, the player does not have to deduct anything from the winnings or declare it in the tax return. However, it is different for winnings from illegal or offshore casinos — they can be considered as other income. Detail in article on tax on winnings .

Demo mode (demo mode/fun play)

A free game with virtual money where you can try the mechanics of the slot machine without your own deposit. The return and math are the same as in the money game. Attention: some Ireland casinos require registration, others offer demo mode even without registration. You can try a number of games in the section for free casino games free .

Wild symbol

A symbol in a slot that acts as a joker — it replaces any regular symbol in a winning combination. It does not replace a scatter or bonus symbol. Variants: classic, expanding (expands to the entire cylinder), sticky (remains in position for several spins), accumulating, wandering, multiplying. Detail in article on pay tables .

Reload deposit

Any deposit after the first — that is, the second, third and subsequent deposits. Some casinos attach their own bonuses to additional deposits (reload bonus, typically 25 - 50% of the deposit up to a ceiling of 1,250 - €). Spinning tends to be milder than with the welcome bonus (20 — 30x).

E

eCOGRA

Electronic wallet (e-wallet)

In Ireland licensed casinos availability is limited, some casinos do not support them at all, others only as one of several options. Revolut in detail in review of Revolut .

Studios in Latvia, Malta and the United States, the croupiers are real people, transmitted live via video. Famous live games: Lightning Roulette, Crazy Time, Monopoly Live, Mega Wheel.

Expanding symbol

A symbol that expands to an entire reel when hit — typically a wild or special bonus symbol. The mechanics significantly increase the chance of winning, as one reel filled with the same symbol essentially "links" all lines. Classic game: Book of Ra and its variations.

F

Rogue casino

A site without a valid license or with a license from an exotic jurisdiction (Curaçao, Anjouan) that pretends to be a legitimate casino, but after a big win will block the account, not recognize the win or disappear. Ireland the player has no legal protection against such a casino. Detail in article about illegal casinos and in comparison licensed vs. Offshore casinos .

Hit rate/hit frequency

The percentage of spins that result in any non-zero win — including a win less than the bet. At low volatility typically 30 — 40%, at high 18 — 25%. Attention: a €7.2 win with a €1 bet is counted in the frequency, even though it is a real loss of €17.2. A higher frequency therefore does not mean a higher return.

Free spins

Bonus currency in the form of free spins on a predetermined slot. Most often as a welcome bonus (50 — 200 free spins) or part of the bonus in the game after the impact of scattered symbols (8 — 25 free spins). Winnings from free spins are often loaded with a spin of 30 — 50x.

A feature in which for 50 — 100x bets you directly activate the bonus game without waiting for scattered symbols. The return on the purchased bonus is usually 95 - 97.5%. Attention: the casino often prohibits the purchase of a bonus when the bonus is active — violation of the terms leads to the rejection of the winnings. Detail in a separate article about buying a bonus .

Example: Sweet Bonanza game, bet €, bonus purchase price 100×= €. After purchase you get 10 free spins with the same probability of a big win as you would with the classic triggering the bonus over 4 scattered symbols.

Croupier (dealer)

A person dealing cards or spinning roulette in a live casino. In the online version, it can be seen via video transmission from the game studio (most often Evolution or Pragmatic Play Live). The term is not used in a slot machine — there a random number generator controls the game.

In classic fruit slots (Respin Joker 81), respin is part of the name of the game — the machine often offers a respin after every win for a small fee for a chance at a higher hand.

RNG (Random Number Generator)

A software component that generates the result of each spin or card. Ireland licensed RNG must be certified (eCOGRA, GLI, iTech Labs) and must not have memory — the result of the next spin does not depend on any previous spin.

Volatility

A measure of how evenly the game distributes winnings over time. Low volatility= frequent small wins, stable budget, suitable for longer play with lower deposit.
