This glossary covers the words that appear on game screens, odds tables, wallet pages and account notices across ach77. Knowing what each term means helps you choose games confidently and move through your account without guesswork.
When a game screen shows a volatility rating or a turnover requirement appears on a information notice, the meaning is not always obvious at first glance. Understanding these terms gives you a clearer picture before you commit a stake or accept a condition.
Terms across the lobby divide into four practical families. Each one lives in a different part of your account and reading flow. Knowing which family a term belongs to tells you where to look when you need more detail.
RTP, volatility, RNG, house edge and payline count appear on game info panels inside slot rooms and live table pages. Studios like PG Soft and Habanero publish these figures where the game provider makes them available — not every title shows all of them.
Asian handicap, over/under, decimal odds and match lines appear on the sportsbook board. Cricket markets — including IPL and BPL fixtures — use these structures. Reading them correctly changes how you interpret a price before placing a selection.
Deposit, withdrawal, transaction limit and e-wallet verification appear on your wallet screen. Whether you move money through bKash, Upay or Bank Transfer, each transaction follows the steps and field labels shown in your account wallet section.
Rollover, turnover, wager requirement and expiry appear in the conditions attached to any active information. These terms define what must happen before a credit becomes available for withdrawal. Always read these in full before accepting a condition.
These are the terms you will encounter most often inside slot rooms and live casino tables. Each definition is kept plain and short so you can check quickly without breaking your session.
RTP stands for Return to Player. It is a percentage showing the theoretical share of total stakes that a slot or table game returns to players over a very large number of rounds.
House edge is the mathematical advantage the platform holds on each game type. It is the complement of RTP, the house edge is roughly 4%.
Volatility describes how a slot distributes its payouts. High volatility means larger wins that appear less frequently. Low volatility means smaller wins that arrive more often.
A wager or turnover requirement is the total amount you must stake before a credited amount becomes withdrawable.
A jackpot is the highest available prize tier in a slot game, triggered by a specific symbol combination or feature round. Some jackpots are fixed at a set amount; others accumulate across rounds. The type and trigger condition are described in each game's paytable.
A live dealer is a real human presenter running a casino table — such as baccarat, roulette or blackjack — via a video stream. You see the dealer and physical table equipment in real time and place your selections through the on-screen interface rather than against a software-generated outcome.
These terms cover the sportsbook board, your wallet screen and the account verification steps. They come up less often than basic game terms but carry significant weight when they do appear.
Asian handicap removes the draw outcome from a match by giving one side a fractional or whole goal start. It reduces a three-way market to two outcomes.
Over/under is a market where you decide whether a measurable statistic — total runs in cricket, total goals in football — will finish above or below a stated number set by the platform. It is entirely separate from which side wins the match and often available alongside match-winner markets.
Rollover is the total staking volume required before a credited amount clears for withdrawal.
An e-wallet is a mobile-based payment account that holds a balance independently of a bank. On ach77, supported e-wallets for Bangladesh include bKash and Upay. Deposits via these wallets follow the steps shown on the payment screen inside your account, including any reference codes the system generates.
KYC stands for Know Your Customer. It is an identity verification process where you submit documents confirming your identity before certain account actions — such as a first withdrawal — are completed. The documents required and the submission method are listed in your account verification section.
Session controls are account-level settings that let you limit how long or how much you engage in a single sitting. Options available may include time reminders or session duration caps. These are found in the account settings area and are managed entirely within your signed-in account page.
Terms rarely appear in isolation. When you open a slot from Joker or CQ9 and check the info panel, you might see both RTP and volatility listed together.
On a PG Soft or Habanero slot info panel, RTP and volatility appear side by side. RTP is a long-run average; volatility tells you the payout rhythm. A high-volatility game with moderate RTP will swing your balance more than a low-volatility game with the same RTP figure.
A cricket sportsbook line may show an Asian handicap alongside a match-winner market. The handicap adjusts the effective run margin, not the match result itself. Reading the handicap value carefully before selecting changes the implied probability you are working with.
When you deposit via bKash, the transaction screen shows a minimum and maximum amount set by the payment configuration.
If your account shows an active credit with a rollover condition, the account notice states the multiple and the remaining staking required. Checking this figure before placing a stake in Aviator Fast Round or Nagad CasinoFast tells you how much of the requirement each session contributes toward clearing.
If a term in the lobby or on your account screen is not covered here, or if a feature behaves differently from what the definition describes, our support routes are the right next step.
The live chat option is accessible from your signed-in account page. Use it when you need a quick explanation of a term you have just seen on a game panel or wallet screen. Share the exact wording and our team will clarify it directly.
For questions about KYC steps, rollover conditions or session control settings, the account support form allows you to describe your question in detail. Submit it from within your account and a response is returned to your registered contact.
The help centre contains published articles on payment processes including bKash, Upay and Bank Transfer steps, account verification requirements and information condition formats. Search by term name to find the relevant article without opening a support ticket.
These questions focus on how to act once you understand a term — where to find a setting, how to read a screen or what step follows a specific account notice.
Open the game info panel before starting a round — usually an information icon inside the game frame. RTP is shown there only when the studio publishes it.
Log into your account and open the information or wallet section. The active credit notice shows the original rollover multiple and the staking volume already completed. The remaining figure updates after each qualifying round or sportsbook selection, depending on what the information conditions specify.
Go to your account settings and locate the verification section. The fields and document types required are listed there. Follow the on-screen instructions to upload what is requested.
After placing a selection on a handicap market, your account bet history records the handicap value alongside the selection and stake. Check the sports history tab in your signed-in account. The result column confirms whether the handicap-adjusted outcome settled in your favour or not.
The transaction limit is set by the payment configuration for bKash. If your amount exceeds the limit shown on the deposit screen, reduce the amount to within the stated range and resubmit.
Session control settings are in the account settings area under your profile. The options available are listed there with their current status. Adjust the settings directly on that screen. Changes take effect as described in the instructions shown alongside each control option.
