This glossary covers the words and abbreviations that appear across our games, odds markets, account wallet and information conditions — so you know exactly what each one means before you act on it.
Seeing an unfamiliar word mid-session can slow you down at exactly the wrong moment — whether you are deciding between a high-volatility slot and a steady live table, or reading the conditions attached to a wallet transaction.
FOUR TERM FAMILIES
Where Each Term Family Appears in the Lobby
Our lobby organises information across four distinct layers — game mechanics, odds markets, wallet language and information conditions. Each layer has its own vocabulary, and knowing which layer a term belongs to tells you where to look for it on screen.
Game Mechanics
Terms like RTP, volatility, payline and multiplier appear on individual game cards or inside the game's information panel. Open any slot title from PG Soft, Habanero, Microgaming or Joker and tap the information icon to see which figures the provider chooses to expose.
Odds and Markets
Asian handicap, over/under, accumulator and decimal odds appear in the sportsbook section, most visibly in cricket markets covering IPL and BPL fixtures. Each term sits next to the market it describes, so the definition and the live number are in the same view.
Wallet and Account
Deposit, withdrawal, e-wallet, KYC and transaction status are found inside your signed-in account area. When you add Nagad or Bank Transfer as a payment method, the wallet screen labels each step — check the field names shown there against the definitions in this glossary.
Information Conditions
Rollover, turnover, minimum odds and validity period appear in the terms attached to any active information. Open the information detail from your account dashboard; each condition is listed before you opt in, so you can read rollover requirements against our definition below.
CORE GAME TERMS
Definitions for Core Game Terms
The six terms below appear most frequently in slot and live casino sections. Each definition is written to match the exact way the word is used inside our lobby.
What is RTP?
RTP stands for Return to Player. It is a percentage showing how much a game is designed to pay back over a very large number of rounds. A higher RTP percentage means a smaller statistical house margin on that title.
What is house edge?
House edge is the mathematical advantage the game holds over time, expressed as a percentage of each wager. It is the inverse of RTP in most slot contexts.
What is volatility?
Volatility describes how a game distributes its payouts — high-volatility games pay larger amounts less often, while low-volatility games pay smaller amounts more regularly. Neither type changes the overall RTP. Volatility is sometimes labelled variance on information panels, especially in Habanero and Microgaming titles.
What does wager or turnover mean?
Wager and turnover refer to the total amount staked across rounds or bets, not the amount won or lost.
What is a jackpot in slot terms?
A jackpot is a prize-style feature built into certain slot titles, triggered by specific symbol combinations or random events within the game engine. The size and trigger rules are defined by the game provider, not by us. No jackpot amount or frequency is guaranteed by the platform.
What is a live dealer?
A live dealer is a human croupier or host who runs a table game — such as baccarat, roulette or blackjack — via a video stream from a studio. You see the dealer and the physical table in real time.
ODDS PAYMENT ACCOUNT TERMS
Odds, Payment and Account Definitions
These six terms come from the sportsbook, wallet and account sections. They are distinct from game mechanics and tend to appear when you are managing money or reading market lines rather than playing a game round.
What is Asian handicap?
Asian handicap is a form of sports betting that removes the draw outcome by giving one team a virtual head start or deficit before the match begins. It is common in football and cricket markets.
What does over/under mean?
Over/under is a market where you predict whether a combined total — runs in cricket, goals in football, or similar — will finish above or below a line set by the sportsbook. The line is visible next to the odds; you choose over or under, not which team wins.
What is rollover?
Rollover is the number of times you must stake the total of a deposit or gameplay amount before you can withdraw it.
What is an e-wallet in our account context?
An e-wallet is a mobile or app-based payment account — such as Nagad — that holds a balance you can use to deposit or withdraw without entering bank card details each time.
What is KYC?
KYC stands for Know Your Customer. It is an identity verification process where you submit documents — typically a national ID — so the platform can confirm your account details match a real person.
What are responsible-play account controls?
These are account-level settings that let you manage how you engage with the platform — such as session time awareness or voluntary pauses. They are separate from promotional terms.
TERMS IN REAL LOBBY DECISIONS
Seeing These Terms Work Together on Screen
Terms rarely appear in isolation — they cluster around specific decisions. When you open a PG Soft slot and see a published RTP figure alongside a high-volatility label, both together tell you that rounds may run long before a larger payout round arrives.
Volatility on a Game Card
When you open the information panel of a Habanero or Microgaming title, the volatility label sits near the RTP figure — if published. Matching that label to your intended session length is the practical use of knowing the definition.
Handicap in a Cricket Market
In a BPL or international cricket match on our sportsbook, the Asian handicap line appears next to the decimal odds. The handicap number shows which side carries the virtual deficit before the first ball is bowled.
KYC Status in the Wallet Screen
Your account dashboard shows a verification status indicator. A verified status unlocks the full withdrawal flow for Nagad and Bank Transfer. Unverified accounts can deposit but face limits on outgoing transfers until documents are reviewed.
Rollover in a Information Detail
Before opting into any active information, the detail panel lists the rollover multiplier, the eligible game types and the validity window. Match each label to the definitions in this glossary to confirm whether the conditions fit your intended activity.
CLARITY AND ACCOUNT HELP
Get Help When a Term or Feature Is Unclear
If a term in the lobby, a information condition or an account field still feels unclear after reading this glossary, our support routes are open.
Live Chat
The live chat button is visible on the site when agents are available. Use it to ask about a specific term as it appears in your account or in a game panel — agents can point you to the exact screen where a label is shown.
Email Support
For questions that need a written record — such as clarifying information rollover conditions or KYC document requirements — email is the right route. The address is published in the site's contact section; allow time for a full written reply.
Help Centre Articles
Our help centre contains published articles on account steps, wallet methods including Nagad and Bank Transfer, and information condition explanations. Search by keyword — such as 'KYC' or 'rollover' — to find the article that matches your question.
USING PLATFORM FEATURES
Questions About Features These Terms Describe
These questions focus on how you interact with the features the glossary terms refer to — not the definitions themselves, but the practical steps in the lobby, account and wallet.
Where do I find the RTP figure for a specific slot on vu99?
Open the game from the lobby, then tap or click the information icon — usually an 'i' symbol inside the game screen. If the provider has published the RTP, it appears there. Not every studio exposes this figure; where it is absent, we do not display an invented one.
How do I check my rollover progress on an active information?
Sign in and go to the information section of your account dashboard. Active information with a rollover requirement show a progress indicator listing how much of the required turnover you have completed. The eligible game categories for that rollover are listed in the same panel.
What documents do I need to complete KYC on my vu99 account?
The KYC screen inside your account lists the accepted document types — typically a national ID or equivalent. Follow the upload instructions shown there. Submitted documents are reviewed before your full withdrawal route, including Nagad and Bank Transfer, is activated.
Can I use Nagad as my e-wallet for both deposits and withdrawals?
Nagad is available as a verified payment method in our account wallet. Once you link your Nagad number and complete any required verification step shown on the wallet screen, it ca
How does volatility affect which slot I choose for a short session?
A low-volatility slot distributes smaller returns more frequently, which tends to extend your session balance across more rounds. A high-volatility slot concentrates returns into less frequent, larger events.
Where do Asian handicap markets appear for cricket on the sportsbook?
Inside the sportsbook, select the cricket category and open a live or upcoming match. Handicap markets appear alongside the main match winner and over/under tabs.
