From RTP and volatility on slot screens to rollover conditions on account pages, this glossary covers the language you actually encounter when browsing 520bd. Use it to read any game label, odds line or wallet notice without stopping to search elsewhere.
Seeing RTP listed on a slot panel means something different from seeing volatility listed beside it — both affect how a session plays out, but in opposite directions.
The lobby organises games, odds, account steps and information notices into distinct screens. Each term family below maps to one of those screens so you know which section to open when a specific word comes up.
RTP, volatility, multiplier, RNG and payline appear on game detail panels inside slot and crash-game rooms. Open a title like Crash Smoke and the information panel beside it shows which of these figures the provider has published. Not every studio exposes all of them.
Asian handicap, over/under, decimal odds and spread sit inside the sportsbook section, most visibly on cricket and football markets. The odds line refreshes as a match progresses, so reading these terms before you open a market saves time when prices are moving.
Deposit, withdrawal, e-wallet, KYC and transaction history all appear on the account page you reach after login. Your Nagad, Upay or Bank Transfer deposit routes are listed in the payment section there; KYC steps appear when identity verification is required.
Rollover, wagering requirement, minimum odds and validity period describe the conditions attached to any information shown in the information tab. Read these before accepting an offer so you know exactly what the account dashboard will reflect once the condition is met.
These six terms appear most frequently in slot lobbies and live casino rooms. Each definition is kept brief so you can scan quickly.
RTP stands for Return to Player. It is the percentage of total bets a game returns to players over a large number of rounds, as published by the provider.
House edge is the mathematical advantage the platform holds on a game, expressed as a percentage of each bet. It is the inverse relationship to RTP carries roughly a 4% house edge. Every casino game has one built in by design.
Volatility describes how often a slot pays out and how large those payouts tend to be. High volatility means less frequent wins that can be larger in size. Low volatility means more frequent wins that are usually smaller. Neither is inherently better; it depends on your session preference.
A wagering or turnover requirement states how many times a bonus amount must be bet before the resulting balance becomes withdrawable.
A jackpot is the highest prize available in a slot game, triggered by a specific symbol combination or feature round as defined by the game provider. Some jackpots are fixed in size; others accumulate across rounds. The game panel states which type applies.
A live dealer is a real person dealing cards or spinning a wheel in a streamed studio environment. You place bets on screen while watching the dealer in real time. Baccarat StarLight and similar titles in the live casino section use this format.
These six terms cover the sportsbook, wallet and account screens — the areas where questions come up most during deposits and market selection.
Asian handicap is a betting market format that removes the draw outcome by giving one team a virtual head start or deficit. It splits a match into two possible outcomes instead of three. Cricket and football markets on the sportsbook use this format regularly alongside standard match-winner lines.
Over/under is a market where you predict whether a measurable match statistic — total runs, goals or points — will finish above or below a number the sportsbook sets. It is one of the most common secondary markets on cricket fixtures during BPL and international series.
Rollover is another term for wagering requirement, used most often in the context of deposit-linked offers. It describes the total bet volume your account must reach before a conditional balance unlocks. The exact rollover figure is published in the information terms visible in the account area.
An e-wallet is a mobile-based payment account — such as Nagad or Upay — that holds a balance you can send or receive without using a bank card directly.
KYC stands for Know Your Customer. It is an identity verification step required by the platform before certain account actions — typically larger withdrawals — are processed. You upload the documents the account page specifies; the step appears as a prompted notice when your account reaches the relevant threshold.
Decimal odds show the total return per unit staked, including your original stake. Odds of 2.50 mean a one-unit bet returns 2.50 units if it wins, giving a profit of 1.50 units. Decimal format is the default display in the sportsbook section and is the easiest format to read quickly.
Terms rarely appear alone — they show up together in the moment you are making a choice. Consider opening Crash Smoke from the crash-game section: the panel beside it may show a multiplier curve and, where the provide
The multiplier in Crash Smoke is the number that grows from 1x upward as the round progresses. You cash out before it stops; if you do not, the round ends and the stake is lost.
Side-bet options in Baccarat StarLight are additional wager positions beyond the main Player/Banker line. Each has its own house edge, which is usually higher than the main bet. The table screen shows which side bets are active and their payout ratio before you place chips.
When you deposit through Nagad, the account page records the transaction immediately in your history. If a KYC notice appears alongside the withdrawal option, it means identity verification is still pending — complete the prompted document step to clear it and unlock the full withdrawal flow.
An over/under line on a BPL or international cricket fixture states a run total; you choose above or below. The decimal odds beside each side show the return per unit.
If a definition here does not fully answer what you see on a specific screen, the support routes below connect you to the team directly.
Open the chat icon on any page inside the logged-in area to ask about a specific term or screen. Describe the section you are looking at — game panel, account page or sportsbook market — so the support team can point you to the right field.
The Help section, accessible from the main navigation after login, contains written references for account steps, payment routes including Nagad and Upay, and information conditions. Search by keyword to find the published explanation for a term you encountered.
Notices inside your account area flag any pending steps — KYC prompts, offer conditions or transaction queries. Read the notice text in full before contacting support; it often contains the specific term definition relevant to your account situation at that moment.
These questions go beyond definitions — they cover how the features each term refers to actually work inside your account and the lobby.
Open the game panel for the slot you want — tap the information icon inside the title screen or on the lobby tile.
Log in and open the information or bonus section of your account page. Information show a progress indicator alongside the rollover figure. The number updates after qualifying bets settle, so check it after each session rather than in the middle of a round.
Deposits through Nagad are available from the payment section of your account regardless of KYC status in most cases. KYC becomes a required step specifically when you request a withdrawal above the threshold shown on the account page — the notice will indicate this clearly.
The handicap line on a live cricket market adjusts in real time as runs are scored and wickets fall.
Cashing out early locks in the multiplier value at the moment you tap the button. Your stake is multiplied by that figure and the result is credited to your account balance.
Open the payment section after login and select Bank Transfer. The account page shows the receiving bank details and a reference code you must include with the transfer.
