This page covers the words and phrases you run into across the okvlk lobby — game mechanics, odds formats, wallet language and account steps. Whether you are checking a payout table or reading a information condition, knowing what each term means puts you in control.
When you know what RTP means, you can compare slot titles with a clear head instead of guessing. When you understand rollover, a information condition stops feeling like a trap and starts being a straightforward calculation.
The okvlk lobby groups terms into four practical families depending on where you encounter them.
Terms like RTP, volatility, house edge and RNG appear on game info panels and paytables. Open any slot or live table card in the lobby and look for the information icon — that is where these figures are shown when the provider exposes them.
Asian handicap, over/under, decimal odds and spread appear on the sportsbook pages. Cricket markets — including BPL and international fixtures — use these formats. The odds format can usually be switched in your account display settings.
Deposit, withdrawal, e-wallet, minimum transfer and processing status are the terms you see on the cashier screen. Nagad and Bank Transfer are the payment rails shown there for supported Bangladesh regions, subject to local law and eligible regions.
Rollover, wagering requirement, qualifying deposit and expiry appear in the terms panel attached to each active information. Always read the rollover figure before opting in — it tells you how many times a bonus amount must be turned over before a withdrawal is available.
Plain definitions for the terms you see most often on game cards and paytables.
RTP stands for Return to Player. It is the percentage of total wagers a game is designed to pay back over a very large number of rounds.
House edge is the mathematical advantage the platform holds on each bet, expressed as a percentage. It is the mirror of RTP carries a 4% house edge. Live table games like baccarat and roulette each have their own published house edge figure.
Volatility describes how a slot pays out — high volatility means larger wins that come less often, low volatility means smaller wins that arrive more frequently. Neither is better; it depends on your session length and how you prefer to play.
A wager is a single bet placed on any game. Turnover refers to the total amount wagered across a session or within a information period. information terms often state a required turnover amount before a withdrawal becomes available.
In slot games, a jackpot refers to the highest prize tier shown on the paytable. Some slots have a fixed jackpot amount; others have a prize pool that grows with play. The paytable inside the game shows the current structure for that title.
A live dealer game streams a real human dealer from a studio to your screen. You place bets through the interface while watching the dealer handle cards or a roulette wheel in real time. Live dealer tables are available in the okvlk lobby under the live casino section.
Definitions for the terms you encounter in the sportsbook, cashier and account verification screens.
Asian handicap is a betting format used mainly in football and cricket that removes the draw outcome by giving one side a head start. It narrows the market to two outcomes and adjusts the odds accordingly. You will see it on most cricket and football match pages in the sportsbook.
Over/under is a market where you predict whether a measurable figure — total runs in a cricket innings, total goals in a match — will finish above or below a line set by the platform. The line and the odds for each side are shown on the market card.
Rollover is the number of times a bonus or deposit amount must be wagered before it converts to withdrawable funds. A rollover of 10x on a 500 taka bonus means 5,000 taka in total wagers must be completed. The exact figure is always in the information terms panel.
An e-wallet is a mobile-based payment account used to send and receive money without a bank card. On okvlk, Nagad is the e-wallet shown on the cashier screen for supported Bangladesh regions. Transactions go through your Nagad account number linked at deposit.
KYC stands for Know Your Customer. It is the identity verification step your account may require before a withdrawal is processed. The account section shows which documents are needed and where to upload them. Completing KYC early avoids delays when you request a payout.
These are account-level controls that let you set boundaries on how much you deposit or wager within a given period. The option is in your account settings. Setting a limit does not close your account — it simply caps activity at the figure you choose until you adjust it.
Seeing a term in isolation is one thing; seeing it in context is more useful. When you open a slot title and tap the info icon, you might see an RTP figure alongside a volatility label.
These two appear together on the game info panel. RTP is the long-run return rate; volatility is the short-run swing pattern. Reading both before you start a session gives you a realistic picture of how that title tends to behave.
On a BPL or international cricket market, the handicap line adjusts the effective margin of victory needed for your selection to win. The sportsbook page shows the line and both-side odds clearly before you confirm.
Every active information on okvlk shows its rollover requirement in the attached terms. Check that figure against your planned session size before opting in — it is the clearest way to know when your balance becomes withdrawable.
The account section flags any outstanding verification step. Uploading the required document there moves your account to verified status, which is what the withdrawal screen checks before it processes a request.
If a term on any screen is not covered here or the explanation does not match what you are seeing in your account, reach out through the routes below.
Open the chat icon from any page in the lobby. The support team can clarify a term, walk through a cashier step or check the status of a transaction on your account.
The help centre is linked in the footer. It has articles covering account steps, payment routes and information conditions in more detail than this glossary page can cover.
For account-specific questions that need a written record — KYC document status, transaction queries — use the email address shown on the contact page. Include your registered account details so the team can locate your record quickly.
Common questions about how the terms above connect to actual steps inside your okvlk account.
Tap the information icon on the game card before you open the title. If the provider has published an RTP figure, it appears there. Not every provider exposes this figure, so some game cards will not show it.
Go to your account settings and look for the display preferences section. The odds format option lets you switch between decimal, fractional and other formats. The change applies across all sportsbook markets immediately after you save it.
Select Nagad on the cashier screen, enter the amount and follow the transfer instructions shown. The screen gives you the receiving number and the reference to include. Once the transfer is confirmed on your Nagad account, the balance updates in your okvlk wallet.
The withdrawal screen will show a prompt directing you to the account verification section. Upload the document listed there. Once the team reviews and approves it, the withdrawal request moves forward. The account section shows the current status of your submission.
Your transaction and wagering history is in the account section under activity or history, depending on the screen layout. The figures there show total wagers placed, which you can compare against the rollover amount stated in the information terms.
Bank Transfer is shown on the cashier screen for supported Bangladesh regions, subject to local law and eligible regions. The cashier page lists the available direction — deposit, withdrawal or both — for each payment rail when you are logged in.
