Guide · Updated July 2026 · The site reference page
Online casino terminology mixes gambling-specific jargon (RTP, volatility, hit frequency) with financial-compliance language (KYC, FICA) and marketing-driven bonus phrasing (sticky bonus, playthrough, max cashout) that's often deliberately vague in promotional copy. This page defines all three categories in one place, in the order you'll actually encounter them: alphabetically. Each entry gives you a working definition in a sentence or two — enough to understand a paytable, a bonus T&C page, or a casino review without confusion — and where we've published a full guide on the topic, we've linked it so you can go deeper. If you're new to online casinos altogether, start with our full guides hub, which organises everything by topic rather than alphabet.
Autoplay — A slot feature that lets you set the game to spin automatically a chosen number of times without manually clicking spin each round, often with optional loss or win limits to stop the sequence early. See our autoplay features explained guide for how to use it without losing track of spend.
Aviator — South Africa's most popular crash-style game, where a multiplier climbs from 1.00x while a plane flies upward, and you must cash out before it "flies away" to lock in a win. Full mechanics in our how to play Aviator guide.
Bankroll — The total amount of money you've set aside specifically for gambling, separate from money needed for living expenses. Managing it properly is covered in our bankroll management tips guide.
Bonus buy — A slot feature letting you pay a fixed multiple of your stake to skip straight into a bonus round (like free spins) instead of waiting for it to trigger naturally. See our bonus buy slots explained guide for the maths behind the cost.
Bonus cash — Bonus funds credited as a cash-equivalent balance rather than free spins, usually subject to wagering requirements before becoming withdrawable. Compared directly with free spins in our free spins vs bonus cash guide.
Cashback bonus — A promotion that returns a percentage of your net losses over a set period, rather than matching a deposit upfront. See our cashback bonuses guide.
Cluster pays — A win mechanic where matching symbols need to land adjacent to each other in a cluster (not on a fixed payline) to pay out — used by titles like Sweet Bonanza. Explained in our cluster pays vs payline slots guide.
Curaçao licence — An offshore eGaming licence issued by the Curaçao gaming authority, held by most online casinos serving South African players, including all three operators tracked on this site. See our Curaçao licence explained guide.
Deposit match bonus — A bonus that matches a percentage of your deposit with bonus funds — for example, a 100% match up to R5,000 doubles your deposit up to that ceiling. See our deposit match bonuses guide.
Demo mode — Free-play versions of casino games using virtual credits instead of real money, useful for learning a game's mechanics risk-free. Covered in our free play and demo mode guide.
EFT (Electronic Funds Transfer) — A direct bank-to-bank payment method; in South Africa, "instant EFT" services like Ozow are the dominant way players fund casino accounts. See our how online casino banking works in SA guide.
Expiry (bonus) — The time window in which a bonus must be claimed, wagered, or used before it's forfeited — commonly anywhere from 24 hours to 30 days depending on the promotion.
FICA — The Financial Intelligence Centre Act, South African legislation whose ID and proof-of-address verification standards have become the reference model most online casinos use for identity checks. See our FICA verification explained guide.
Free spins — A set number of no-cost spins on a specific slot, awarded as a bonus or triggered as an in-game feature, with any winnings usually subject to wagering requirements. See our free spins guide.
Game weighting / contribution — The percentage of a wager on a specific game that counts toward clearing a wagering requirement — often 100% for slots and 0–10% for table games. Full explanation in our guide to why some games are excluded from bonus wagering.
Hit frequency — How often a slot pays out anything at all, expressed as a percentage of spins that produce a win of any size, regardless of amount. See our slot hit frequency guide.
Hot/cold slot myth — The false belief that a slot machine runs in cycles of being "due" for a win or "cooling off" after a payout. Every spin on a certified RNG game is independent. Debunked fully in our hot and cold slots explained guide.
House edge — The built-in mathematical advantage a casino holds over players on any given game, expressed as a percentage of every wager the casino expects to keep over the long run. See our understanding casino house edge guide.
Instant EFT — See EFT. The dominant South African online payment style, led by providers like Ozow, that redirects you to your own bank login rather than requiring card details.
Jackpot (progressive) — A prize pool that grows continuously as players wager on linked machines or games, seeded from a small percentage of every bet, until someone hits the trigger and the jackpot resets. See our how progressive jackpots work guide and our broader jackpot slots explained guide.
KYC (Know Your Customer) — The identity verification process casinos run to confirm you are who you claim to be before releasing withdrawals. See our full KYC verification guide.
Live dealer — Casino table games (blackjack, roulette, baccarat) streamed in real time from a studio with a real human dealer, rather than generated by RNG software alone. See our how to play live dealer games guide.
Maximum cashout limit — A cap on how much of your bonus-derived winnings can actually be withdrawn, regardless of your balance — most common on no-deposit bonuses. See our maximum cashout limits guide.
Megaways — A licensed slot mechanic (developed by Big Time Gaming) that randomises the number of symbols per reel each spin, producing up to 117,649 ways to win. See our Megaways slots explained guide.
Minimum deposit — The smallest amount a casino allows you to deposit in a single transaction, often as low as R10–R30 for methods like Ozow at Pantherbet and 10bet.
Multiplier — A feature that multiplies a win by a fixed or random factor (2x, 5x, 100x), common in bonus rounds and crash games alike. See our multiplier slots explained guide.
National Gambling Act — The core South African legislation establishing the national and provincial gambling regulatory structure. See our history of online gambling in South Africa guide.
No-deposit bonus — A bonus (cash or free spins) awarded without requiring any deposit from the player, usually carrying strict wagering requirements and a maximum cashout cap. See our how to claim no-deposit bonuses guide.
Ozow — South Africa's leading instant EFT payment provider, redirecting players into their own bank login to complete a deposit without ever entering card details. See our Ozow payment guide.
Paytable — The in-game reference screen showing what each symbol pays, how bonus features trigger, and the game's RTP and volatility. See our how to read slot paytables guide.
Payline — A fixed pattern across a slot's reels that must be matched with symbols to produce a win, as opposed to cluster pays or Megaways-style mechanics.
Playthrough — Another term for wagering requirement — the total amount you must bet before bonus winnings become withdrawable.
Provincial gambling board — One of nine regional South African regulators responsible for licensing physical, premises-based gambling within their province. See our gambling board vs provincial licensing guide.
RNG (Random Number Generator) — The certified software algorithm that determines the outcome of every spin, shuffle or roll in an online casino game, tested independently before games go live. See our how random number generators work guide.
RTP (Return to Player) — The theoretical percentage of all money wagered on a game that's projected to be paid back to players over its full lifetime. See our what is RTP in slots guide and our online vs land-based slot RTP guide.
Self-exclusion — A voluntary tool letting a player lock themselves out of a casino account, or all licensed accounts in some jurisdictions, for a set or indefinite period. See our self-exclusion guide.
Sticky bonus — A bonus that stays attached to your balance and can't be withdrawn separately from your own funds until wagering is complete, as opposed to a "non-sticky" bonus that's removed before you withdraw your own deposit.
VIP / loyalty programme — A tiered rewards system that gives more frequent or higher-staking players better perks — cashback rates, faster withdrawals, dedicated support — as they climb tiers. See our are VIP programs worth it guide.
Volatility (variance) — How a slot distributes its wins: low volatility pays smaller amounts more often, high volatility pays rarely but bigger. See our what is slot volatility guide.
Wagering requirement — The multiple of a bonus (and sometimes deposit) amount you must bet through before resulting winnings become withdrawable. See our full wagering requirements explained guide and our bonus terms glossary for related phrasing.
Welcome bonus — The promotional package offered to new players on their first deposit(s), often combining a match percentage with free spins. See our welcome bonuses guide.
Mzansi Pro-Tip
The two terms worth memorising above all others, if you only remember two, are RTP and wagering requirement. RTP tells you how a specific game is mathematically built to pay back over time; wagering requirement tells you how much real betting volume stands between a bonus and an actual withdrawal. Almost every other term on this page exists to add nuance to one of those two ideas — volatility refines RTP, game weighting refines wagering requirements, and so on.
If a term you've run into isn't listed here, it may be covered in more depth in our dedicated bonus terms glossary or our South African casino slang glossary, which covers more casual, community-driven terminology rather than formal industry language.
It's tempting to skim past unfamiliar terms in a bonus T&C page or a slot's paytable and just start playing — most players do. But a surprising share of the frustration players report with online casinos traces back to a handful of specific terms that were misunderstood rather than any operator behaving dishonestly. A player who doesn't know what "game weighting" means might spend hours at the blackjack table wondering why their wagering bar barely moves. A player unfamiliar with "maximum cashout limit" might be blindsided when a big no-deposit win gets capped on withdrawal. A player who's never heard of "hit frequency" might judge a slot as "broken" simply because it's a naturally low-frequency, high-volatility title doing exactly what it was designed to do.
This is precisely why we built this glossary as a standalone reference rather than burying definitions inside individual guides only. Casino terminology sits at the intersection of gambling mechanics, financial compliance and marketing language, and South African players specifically navigate an extra layer most international glossaries don't cover — FICA-style verification, Rand-based minimums, instant EFT payment culture, and the offshore-licensing reality that shapes so much of how local players interact with the industry. Understanding the vocabulary properly is, in a very real sense, understanding how to protect your own money and time.
Every term on this page maps to a decision you'll actually make as a player. Choosing between two slots often comes down to comparing RTP and volatility together, not either alone — a high-RTP, high-volatility title and a slightly-lower-RTP, low-volatility title can suit completely different bankrolls and risk appetites, which is exactly why our high-volatility slots guide and low-stakes slots guide exist as separate, deliberately different recommendations. Choosing a bonus often comes down to reading past the headline percentage to the wagering requirement, game weighting and max cashout limit together — three separate terms that jointly determine whether a bonus is genuinely useful to how you plan to play.
Even seemingly administrative terms like KYC and FICA connect directly to your bottom line: understanding that verification is a one-time process best completed early, rather than something to scramble through after a big win, is the difference between a same-day withdrawal and a week of back-and-forth document resubmission. That's the throughline across every entry in this glossary — plain-English definitions that exist to help you make faster, better-informed decisions rather than just to sound knowledgeable in a casino forum.
This glossary is intentionally a starting point, not a finishing point — every term above links through to a full guide with worked examples, step-by-step processes, and South Africa-specific context where it matters. If you're brand new to online casinos, we'd suggest reading our legal status guide, FICA verification guide and RTP guide first, since those three cover the foundational "am I allowed to, how do I prove who I am, and how does the maths work" questions almost every new player has. From there, our full guides hub organises everything else by topic — game rules, slots, South Africa-specific banking and legal questions, strategy, and deep dives — so you can go from a glossary definition to a complete, practical guide in one click.
And if you're ready to put any of this into practice, our reviews of Pantherbet, 10bet and Hollywoodbets apply every term on this page to three real, verified South African operators — so you can see exactly how RTP, wagering requirements, KYC and licensing play out in practice rather than just in theory. Our rating methodology explains how we weigh all of it when deciding what to recommend.
Common questions
RTP is the theoretical long-run percentage of wagered money a game pays back. Volatility describes how those payouts are distributed — frequent and small (low volatility) or rare and large (high volatility). Two slots can share the same RTP and feel completely different to play because of volatility.
Wagering requirement — it determines how much you need to bet before any bonus-derived winnings become withdrawable at all. Game weighting and maximum cashout limits both modify how that requirement plays out in practice.
Not exactly. FICA is specific South African legislation around financial verification. KYC is the broader, internationally used term for identity verification generally. Most South African-facing casinos model their KYC process on FICA's familiar document standards even when not directly bound by the Act.
A sticky bonus stays merged with your balance and can't be cashed out separately — you need to clear the wagering requirement on the combined balance before withdrawing anything, including your own deposited funds in some structures.
Because most online casinos serving South African players, including the operators reviewed on this site, hold an offshore Curaçao eGaming licence rather than a South African online-specific licence, given the current provincial licensing framework's focus on physical premises.
Both — most terms (RTP, RNG, volatility, wagering) are universal to online casinos worldwide, but we've included South Africa-specific entries like FICA, provincial gambling boards and Ozow/instant EFT terminology that a generic international glossary would leave out.
We review and update it as new terms become common in bonus terms, game mechanics or payment methods, and whenever we publish a new in-depth guide that deserves a glossary entry and link.
