Mobile / Slots
From RTP and volatility on the slots floor to rollover conditions on the account wallet, this glossary maps out the exact words you will encounter when you browse our catalog, place a wager or move funds through bKash, Nagad or Rocket.
Lobby screens at bas99 display a lot of information at once — payout tables, market lines, wallet prompts, category filters. When you know what each label actually means, you move faster. You pick the right volatility level for the session length you have.
Different parts of the lobby surface different vocabulary. Game pages use mechanics language. Sportsbook pages use odds language. The wallet area uses payment and account language. Information notices use condition language. Knowing which family a term belongs to tells you where to look for it.
Terms like RTP, volatility, payline, multiplier and feature round appear inside the individual game frame or on the game detail card.
Asian handicap, over/under, match odds and spread are sportsbook terms. They appear on the market row next to each event — including cricket fixtures during BPL and international series. Read the market label carefully; the number next to it is the line, not the payout multiplier.
Deposit, withdrawal, e-wallet, transfer confirmation and transaction ID are account-area terms. You see them in the wallet tab after you connect bKash, Nagad or Rocket to your account. The transaction ID appears on both the lobby receipt and your mobile wallet history.
Rollover, turnover requirement, qualifying wager and minimum odds are the terms attached to any offer on the promo board. They define exactly what activity counts before a gameplay becomes withdrawable. Read each condition line before accepting; misreading rollover is the most common account confusion we see.
These are the six terms that appear most often across the slots and live casino sections of the lobby. Each definition is kept to plain language.
RTP stands for Return to Player. It is the percentage of all wagered money a game is designed to pay back over a very large number of rounds.
House edge is the mathematical advantage the game holds over the player, expressed as a percentage of each wager. It is the mirror of RTP has a 4% house edge.
Volatility describes how often and how large a slot pays out. High volatility means wins arrive less often but tend to be larger when they do. Low volatility means smaller, more frequent wins.
A wager or turnover requirement is the total amount you must stake before a credited gameplay can be withdrawn.
Jackpot refers to a prize-style feature in certain slot titles where an accumulating or fixed prize pool can be won during a specific in-game event. Not every slot carries a jackpot feature. Where a title includes one, the game frame displays the current pool value and the trigger condition.
A live dealer is a real person, filmed in a studio, who runs a card or table game in real time while you play through the lobby screen on your device.
These six terms cover the sportsbook, wallet and identity sections of the platform — the areas where unfamiliar language tends to cause account delays.
Asian handicap is a betting market format that removes the draw outcome by giving one side a head start expressed as a fraction or whole number.
Over/under is a market where you wager on whether a measurable figure — runs scored, total goals, corners — will finish above or below a line set by the sportsbook.
Rollover is another word for a turnover requirement attached to a credited amount. It specifies the minimum total staking activity required before withdrawal is permitted. Check the condition attached to any credited amount in your account wallet — the rollover figure and the qualifying game categories are listed there.
An e-wallet is a mobile money account — bKash, Nagad or Rocket — linked to your bas99 account for moving funds in and out of the lobby. Transactions appear in the wallet tab of your account.
KYC stands for Know Your Customer. It is the identity verification step the platform runs before processing a withdrawal. You submit a government-issued document through the account settings page. The specific documents accepted and the submission fields are listed in the verification section of your account.
Responsible-play limits are account-level controls you set yourself — such as session time awareness tools or wager tracking — to stay within a spending range you choose. These controls are configured in the account settings section. Check the settings page for the options your account region makes available.
Reading a definition once is useful. Seeing how three or four terms combine on a single screen is more useful still. When you open Dragon Tiger Fast Table, the live dealer section shows you the table limit range — that is the minimum and maximum wager the seat accepts.
Open any slot from Habanero, PG Soft or Spadegaming and tap the information icon. If the studio exposes RTP for that title, it appears there.
On a BPL or international cricket fixture, the Asian handicap line sits next to the match odds column.
When you request a withdrawal to your Rocket or Nagad wallet, the account page will prompt KYC if it has not been completed. The verification section lists acceptable documents and the upload fields. Completing it once covers all future withdrawals; you do not repeat it each time.
Your account wallet shows a transaction log with timestamps and reference numbers for every deposit and withdrawal. If you have an active rollover condition, the progress meter sits in the information section of the account area — not in the main wallet view — so check both tabs separately.
If a term on the lobby screen, in an account prompt or on the promo board is not covered here, or if the definition does not match what you are seeing in your session, reach out through the routes we publish on the site.
The live chat button sits at the bottom of every page. Open it and describe the term or screen you are asking about — include the section name (e.g. wallet, promo board, game frame) so the support agent can locate the exact context quickly.
Send a detailed message through the email address listed on the Contact page. Include your account ID and the specific term or screen prompt that is unclear. Email is useful for follow-up questions where you want a written response you can refer back to.
The Help section inside your logged-in account covers wallet, KYC and information condition queries with step-by-step notes. Check it first for common questions about bKash, Nagad or Rocket transaction references — many answers are available there without waiting for a reply.
These questions are about how the platform works, not about what a term means in isolation.
Tap the information icon inside the game frame after you launch the slot. RTP is displayed there if the studio has published it.
Open the information section inside your logged-in account. A progress meter shows how much of the required turnover you have completed and which game categories are counting toward it. The wallet tab shows transaction totals but not rollover progress — you need the information tab specifically.
Both bKash and Nagad are available as wallet options in the account payment section. You can connect one or both. Each withdrawal goes back to the wallet used for the originating deposit unless you update the preferred wallet in account settings. Rocket is also available as a configured option.
The account verification page shows the status of each submitted document. If a document is not accepted, the page displays the reason and lists what is required instead.
Every term in this glossary describes a feature that works the same way whether you are on a phone or a laptop.
Open the sportsbook section and select the cricket category. Choose the fixture you want — BPL, international or IPL markets where available. The market rows beneath the fixture name include match odds, Asian handicap and over/under totals. Tap the row to expand the available line options for that match.
