Online Casino Glossary: Key Terms Every Rollingo Player Should Know
Why a Casino Glossary Is Worth Bookmarking
Online casino terminology can feel like its own language, especially for players who are new to the space. Terms like RTP, wagering requirement, and volatility appear throughout bonus terms, game descriptions, and promotional pages, and understanding them properly changes how you evaluate an offer or a game. This glossary collects the most important terms you’ll encounter while playing at Rollingo, explained in plain language. Keep this page handy, and feel free to return to the main site whenever you want to put these terms into practice.
Bonus and Promotion Terms
Welcome Bonus — A promotional offer extended to new players, typically a percentage match on a first deposit, up to a stated maximum amount.
Wagering Requirement, also called playthrough — The number of times a bonus amount, or bonus plus deposit, must be wagered before associated winnings become withdrawable. Expressed as a multiplier, such as 30x or 40x.
Free Spins — A set number of spins on a specified slot or slots, awarded without requiring additional deposit, with winnings usually subject to their own wagering requirement.
Cashback — A partial refund of net losses over a given period, often calculated weekly, and typically carrying lower wagering requirements than deposit-based bonuses.
Maximum Bet Restriction — A cap on the stake size allowed per spin or hand while a bonus is active; exceeding it can void bonus winnings.
Game Mechanics Terms
RTP (Return to Player) — The theoretical percentage of all wagered money a game returns to players over a very large number of rounds. An RTP of 96%, for instance, implies an average house edge of 4% over the long run, though any individual session can vary widely.
Volatility, or Variance — How a game distributes its payouts. Low volatility games pay smaller amounts more frequently; high volatility games pay less often but can produce much larger individual wins.
RNG (Random Number Generator) — The certified algorithm responsible for producing random, independent outcomes in digital casino games, regularly audited by independent testing labs.
Paylines — The patterns across a slot’s reels along which matching symbols must land to produce a win; modern slots sometimes replace fixed paylines with ways-to-win or cluster-pay mechanics.
Account and Payment Terms
KYC (Know Your Customer) — The identity verification process operators are required to complete, usually before a first withdrawal, involving documents such as a government ID and proof of address.
Pending Period — A short delay built into the withdrawal process during which a player can still cancel the request; after this window, the withdrawal moves to processing.
Self-Exclusion — A responsible gambling tool allowing a player to voluntarily restrict their own account access for a defined or indefinite period.
Session Limit — A tool allowing players to cap how long or how much they play within a set timeframe, as part of responsible gambling features.
Regulatory and Fairness Terms
- License Number — The unique identifier tying an operator to a specific regulator, verifiable on that regulator’s public register
- Curacao-style Licensing — A streamlined international licensing framework commonly used by multi-market operators
- Independent Testing Lab — A third-party organization that certifies RTP figures and RNG fairness
- Responsible Gambling Tools — The collective suite of deposit limits, time reminders, and self-exclusion options required by most licenses

More Terms Worth Knowing
Jackpot — A prize pool that grows over time, either fixed at a preset ceiling or progressive, meaning it increases with every wager placed across a network of games until someone wins it.
Live Dealer Game — A table game such as blackjack or roulette streamed in real time with a human dealer, blending the pace of a physical casino with the convenience of playing online.
Deposit Match — Another name for a percentage-based bonus tied to a deposit, such as a 100% match, where the operator adds bonus funds equal to a set percentage of the amount deposited.
House Edge — The mathematical advantage built into every casino game, representing the inverse of RTP; a 96% RTP game, for example, carries a 4% house edge over the long run.
Putting the Glossary to Work
Understanding this vocabulary changes how you read a promotion. A 100% match sounds appealing on its own, but once you factor in the attached wagering requirement, maximum bet restriction, and expiry window, you get a much more complete picture of its real value. The same applies to game selection — knowing the difference between RTP and volatility helps you pick titles that actually match the kind of session you want to have, rather than relying on marketing copy alone.
We’ll continue expanding this glossary as new terms become relevant, but the entries above cover the vocabulary you are most likely to need during your first few sessions, from your very first deposit through to your first withdrawal request.
