This glossary covers the words and abbreviations you run into across bd520 — from game mechanics like RTP and volatility to wallet actions like bKash deposit and KYC verification.
When you open a slot title and see a volatility label, or when the cashier screen shows a rollover condition next to a balance, those words carry real meaning.
The lobby surface, cashier screen, account dashboard and information panel each carry their own vocabulary. Mapping where a term appears helps you recognise it in context before you act.
Labels like RTP, volatility, RNG and payline appear on individual game detail screens and in the studio information tab. Habanero and Pragmatic Play titles surface these where the provider exposes them — not every title displays a figure.
Asian handicap, over/under and decimal odds appear on the sportsbook panel, most visibly on cricket markets covering international fixtures and BPL matches. The odds format can usually be switched in your account settings.
Deposit, withdrawal, e-wallet, transaction ID and KYC are the words you see on the cashier and account verification screens. When you add funds via bKash or Nagad, the transaction reference shown there is your proof of payment.
Rollover, wagering requirement, minimum odds and qualifying deposit appear in the terms attached to any active information. Read these on the information detail page before you accept a balance adjustment — the numbers there are the binding ones.
These six terms appear on game screens and in lobby filters. Each definition below is the standard industry meaning as it applies inside the bd520 lobby.
RTP stands for Return to Player. It is the theoretical percentage of total wagered money that a game pays back over a very large number of rounds. A figure is shown only where the game provider publishes it — bd520 does not fabricate or adjust the number.
House edge is the mathematical advantage the game holds over the player, expressed as a percentage of each bet. It is the mirror of RTP carries a 3% house edge. This is a statistical average across many rounds, not a per-session guarantee.
Volatility describes how often a slot pays and how large those payouts tend to be. High volatility means infrequent but potentially larger wins. Low volatility means smaller, more regular payouts. The label appears on the game detail screen where the studio supplies it.
A wagering or turnover requirement states how many times a qualifying balance must be bet before it can be withdrawn. The multiplier and eligible games are listed in the information terms; the current progress is visible in your account dashboard.
A jackpot is the highest prize tier a slot can award, either a fixed amount set by the game or a progressive amount that grows as players wager. bd520 displays jackpot availability on the relevant game card where the studio exposes that data.
A live dealer is a human host filmed in a studio environment, dealing cards or spinning a wheel in real time. You watch via a video stream and place bets through on-screen controls. Baccarat RoyalFlush is one example available in our live casino section.
These six terms cover the sportsbook, cashier and account verification areas — the vocabulary you encounter once you move beyond the game lobby itself.
Asian handicap is a betting market that removes the draw outcome by giving one team a virtual goal advantage or deficit before the match starts.
Over/under is a market where you predict whether a measurable total — runs in a cricket innings, goals in a match — will finish above or below a line set by the sportsbook. You do not pick a winner; you predict a combined total against that line.
Rollover is another word for wagering requirement. It specifies how many times a bonus or credited balance must be cycled through qualifying bets before a withdrawal is permitted. Always check the rollover figure in the information terms before accepting a credit.
On bd520, e-wallet refers to mobile money accounts such as bKash, Nagad and Rocket. These are the local payment rails through which you move funds between your mobile account and your bd520 wallet. Transactions are recorded on both the provider app and your bd520 history.
KYC stands for Know Your Customer. It is an identity verification step where you submit documents confirming your name and account ownership. bd520 triggers KYC before processing certain withdrawals; the required documents and upload path are shown in your account settings.
Minimum odds is the lowest decimal or fractional price a qualifying bet must carry for it to count toward a rollover or information condition.
Glossary definitions become useful when you can trace them to a specific screen or decision point. Consider a session starting with a bKash deposit: you open the cashier, enter the amount, and the confirmation screen s
Generated at the moment your bKash or Nagad transfer completes. It appears on the cashier confirmation screen and inside your bd520 account transaction history. Quote it to the support team if a deposit needs investigation.
Shown on the game detail card for eligible titles from studios like Pragmatic Play and Habanero. It is a studio-supplied classification, not a bd520 editorial rating. Use it to match a game's payout rhythm to your current session preference.
Visible as a progress bar or figure inside your active information panel once you have accepted a credited balance. The counter updates after qualifying bets settle, letting you track how close you are to the withdrawal threshold.
Before placing a sportsbook bet toward a rollover condition, open the information detail and confirm the minimum odds figure. A bet on an ineligible odds tier still settles normally but will not register toward your rollover counter.

These questions are about using the actual platform features behind the glossary terms — not just what a word means, but how it works on bd520 specifically.
Open the game's detail or information tab inside the lobby. If the studio — for example Habanero or JDB — has published an RTP figure, it appears there. Where the studio does not expose it, no figure is shown; we do not substitute an estimate.
Log in and open the Information or Bonus section of your account dashboard. Information display a progress counter that updates as qualifying bets settle. The information detail page also restates the rollover multiplier and any minimum odds condition.
The required documents and upload instructions are shown inside the Verification section of your account settings. The specific requirements can vary by account status, so follow the steps listed there rather than a fixed external list.
Yes. Open your account settings and look for the odds format preference. You can switch between decimal, fractional and other available formats. The change applies across all sportsbook markets, including cricket and football fixtures.
After a successful deposit, the transaction ID generated by bKash or Nagad is stored in your bd520 transaction history under the Wallet or Payments section. It is the reference to quote when contacting support about a pending or disputed deposit.
Volatility describes payout frequency within the game itself and has no effect on rollover tracking. Each eligible bet contributes its stake value toward the rollover counter regardless of the game's volatility rating, as long as the game qualifies under the information terms.
