Every term on this page maps to something you will see inside the mdn99 lobby — a slot mechanic, a live table rule, an account wallet label or a sports odds format. Work through these definitions once and the lobby reads differently: faster to browse, easier to decide.
If a term in the lobby or on a table screen does not match what you expect, our support channels are the fastest way to get a straight answer. Contact us before acting on any rule you are unsure about — especially for wallet labels, wagering conditions or payout displays.
Open the chat widget from any lobby page. Describe the term or screen label you are seeing, and our team will explain what it means in plain language for your account type.
Send a screenshot of the term or condition you are querying. Email support is suited for detailed questions about rollover requirements, KYC document steps or DuitNow transfer labels.
Your account dashboard shows active wallet balances, transaction history labels and any conditions attached to your account in real time. Check there first before contacting us.
When a slot screen shows a volatility rating or a live table displays a side-bet payout ratio, that language is not decoration — it tells you how the game behaves before you place a wager. The same logic applies to your wallet: understanding what a rollover requirement means stops you from making a transfer at the wrong time. This glossary covers the terms that appear most often across slots from Pragmatic Play and Spadegaming, live dealer tables, fish-shooting rounds, and your account wallet — whether you fund through DuitNow, Touch 'n Go eWallet or FPX. Each definition here is written in plain language, not taken from rule-book text. Use it to navigate the lobby with a clearer idea of what each screen is actually telling you.
Terms cluster around four areas of the lobby. Knowing which family a term belongs to tells you where to look for it — and what action it is connected to.
RTP, volatility, paylines, bonus rounds, multipliers and scatter symbols appear on individual game info panels. In Rapid Mines Board and Fishing Deep Sea Arena you will also see multiplier paths and prize-cap displays tied to round progression.
Asian handicap, over/under, decimal odds and money-line formats are shown directly on the sports markets page. Football markets — including Liga Super matches — display these formats side by side so you can switch between them.
Deposit, withdrawal, wallet balance, pending balance and transaction reference numbers all appear inside your account dashboard after login. DuitNow and FPX transfers each generate a unique reference you can match to a transaction row there.
Rollover, turnover requirement, minimum deposit threshold and qualifying game — these labels sit inside any active condition displayed in your account. Read these before moving funds to avoid invalidating a qualifying period.
These are the terms that appear on slot info panels, live dealer tables and fish-shooting rooms across the mdn99 lobby.
Return to Player — the percentage of total wagers a game is designed to return over many rounds. RTP is displayed where the game or studio chooses to publish it; not all titles show it.
The mathematical advantage the game holds on each round, expressed as a percentage. A 2% house edge means the game expects to retain 2% of every wager placed across all rounds over time.
Volatility describes how a slot pays out — high volatility means larger prizes hit less often; low volatility means smaller prizes appear more frequently. It affects how a session feels, not just the final amount.
A condition requiring you to bet a set multiple of a credited amount before it can be transferred to your withdrawable balance. The exact multiple and qualifying games are shown in your account dashboard.
A jackpot is the slot's top prize, awarded on a specific rare combination or triggered randomly depending on the game design. It is a game mechanic, not a schedule — when it hits depends on the game's own rules.
A real person dealing cards or spinning a roulette wheel from a studio feed, streamed to your screen in real time. Live Kuala Lumpur Table on mdn99 runs this format with on-screen bet placement.
These definitions cover the language you encounter in sports markets, your wallet flow and account verification — areas where a misread term can affect a transfer or a bet placement.
A football betting format that removes the draw outcome by giving one side a fractional goal advantage. Used widely in Liga Super markets, it narrows the bet to two outcomes instead of three.
A market where you predict whether a combined score or stat total will exceed or fall short of a number set by the market. Liga Super Over Under displays this threshold directly beside the match listing.
The number of times you must wager a credited amount before withdrawal is permitted. Each qualifying bet placed on eligible games counts toward the total; your dashboard tracks the running figure.
A digital payment account — such as Touch 'n Go eWallet — linked during deposit or withdrawal setup. Funds move between your e-wallet and your mdn99 account wallet through the payment screen in your account.
Know Your Customer — an identity verification step where you submit documents to confirm your account details match your identity. mdn99 prompts for KYC at specific account milestones; instructions appear on the verification screen.
A way of expressing the total return per unit staked, including your original stake. Decimal odds of 2. 50 mean a one-unit wager returns 2. 50 units total if the outcome is correct. Switchable on the sports page.
Terms rarely appear alone — they combine at the moment you make a lobby decision. When you open Rapid Mines Board, the game panel shows volatility class and whether a multiplier path is active; both terms from this glossary apply at once. On Fishing Deep Sea Arena, a prize-cap display tells you the ceiling for a given round — that is the jackpot mechanic in a fish-shooting format rather than a reel slot. Understanding that both are prize-cap structures makes switching between them natural rather than confusing. In the sports section, Asian handicap and over/under appear side by side on the same Liga Super match row. Once you know each format's logic, you can choose which one fits how you read the fixture — without needing to re-read the rules every time. The same applies on the account side: when a DuitNow deposit lands, your dashboard shows a pending balance separate from your withdrawable balance. Those two labels are account terms from this glossary, and recognising them immediately tells you where your funds stand before you navigate to a game.
Volatility class and multiplier path are both shown on the game panel. Reading both together before a round tells you how the session is likely to move — frequent small steps versus longer waits for a larger multiplier hit.
Prize-cap displays the maximum return available in the current round. This is the jackpot mechanic in a fish-shooting context — the cap resets when hit, just as a slot jackpot does after it pays out.
The over/under threshold sits next to the match in the sports markets view. Decimal odds for each side of the line are shown alongside so you can read both the threshold and the return format at one glance.
After a DuitNow transfer completes, your dashboard separates the pending balance from the withdrawable balance. These two account terms tell you precisely what is available to wager and what is still being confirmed.
These questions cover how the terms here connect to actual steps inside your account, the lobby or the payment screen.
Open the game panel before launching the title — studios like Pragmatic Play and CQ9 display volatility class and RTP where they choose to publish it. Not every title shows both figures; check the panel for what is available.
Log into your account and open the dashboard. Any active rollover requirement shows a running total alongside the qualifying game list. The figure updates each time a qualifying wager is confirmed on the account.
Yes — the sports page includes an odds format toggle. Switch between decimal and Asian handicap views on the same market without leaving the Liga Super or other football match page you are on.
Your dashboard shows the status of each transaction in real time. Pending balance moves to withdrawable once the transfer is confirmed; the timeline depends on the payment rail and any active account conditions.
The KYC screen inside your account lists the exact documents needed at that verification stage. Requirements vary by account milestone; follow the instructions shown on the verification screen rather than assuming a fixed set.
Use this glossary first, then open live chat if you still need clarification. For table-specific rules on Live Kuala Lumpur Table, the dealer's on-screen rule panel also covers the main mechanics in short form.
