From RTP and volatility to KYC and rollover, this glossary covers the terms you see while navigating the kt990 lobby, managing your bKash or Nagad wallet, and reviewing your account activity.
Seeing an unfamiliar term mid-session can slow you down. When you know what house edge means before opening a table, or what rollover means before reading a information condition, you make decisions based on actual rules rather than guesswork.
Terms group naturally by where you encounter them. Game mechanics appear on the game detail card and in the paytable. Odds language appears in the sportsbook section, especially on cricket markets like BPL and international fixtures.
Terms like RTP, volatility, paylines and multiplier appear on the game detail card before you start a round.
Asian handicap, over/under, decimal odds and spread show up in the sportsbook panel — most visibly on cricket match pages for BPL and international fixtures. Each market line sits next to the selection so you can read the implied probability before adding it to your slip.
Deposit, withdrawal, minimum threshold, e-wallet and transaction ID are the terms you meet at the cashier. When you fund an account through bKash or Nagad, the screen shows a transaction reference number — that is your transaction ID for support queries.
Rollover, qualifying deposit, wagering requirement and opt-in are the four terms that govern whether a information applies to your account. They appear in the offer detail panel.
These are the definitions most frequently searched before opening a game for the first time. Each answer is the working definition as it applies to games available in the kt990 lobby.
RTP stands for Return to Player. It is the percentage of all wagered money a game returns to players over a statistically large number of rounds. It is shown only where the game provider publishes it — not on every title.
House edge is the mathematical advantage the game holds over time, expressed as a percentage of each wager. A house edge of 2% means the game retains roughly 2 units for every 100 wagered across a long session average.
Volatility describes how often a slot pays out and in what size. High volatility means larger but less frequent wins. Low volatility means smaller, more frequent payouts. The paytable or game info panel is where this is usually disclosed.
A wager is a single confirmed bet placed with real or bonus funds. Turnover is the running total of all wagers placed. Information conditions often require a minimum turnover before a gameplay can be withdrawn from the account.
A jackpot feature is a prize-style slot mechanic where a large prize pool can be won, usually triggered by a specific symbol combination. RTP information for jackpot mechanics is shown only when the provider discloses it.
A live dealer game streams a human dealer running a real table — cards, roulette wheel or dice — in real time. You see the action via video feed and place bets through on-screen controls, the same as a standard table game interface.
These terms come up most at the sportsbook, at the cashier, and during account verification. Understanding them helps you move through those screens without having to pause and search.
Asian handicap removes the draw outcome from a match by giving one side a head start in goals or runs. It is common on cricket and football markets and reduces the number of possible outcomes from three to two, which affects the odds shown.
Over/under is a market where you predict whether a combined score or statistic will be above or below a set line. In cricket, the line might be total runs in an over or innings. The sportsbook shows the line value next to the market name.
Rollover is the number of times you must wager the bonus amount — or sometimes the deposit plus bonus — before the balance becomes withdrawable. The exact multiplier and qualifying games are stated in the offer's detail panel.
An e-wallet is a mobile-based payment account that holds a balance you can use to deposit or withdraw. On kt990, bKash and Nagad are the e-wallets you will see named on the deposit and withdrawal screens for Bangladesh accounts.
KYC stands for Know Your Customer. It is the verification process where you submit identity documents so the platform can confirm your identity before processing withdrawals. Your account dashboard shows which documents are still required.
A transaction ID is the unique reference number generated when a deposit or withdrawal is processed. When you send money via bKash or Nagad, both the wallet app and the kt990 cashier screen display this number — keep it for any support query.
Consider a session where you open the slots section and see three titles from Habanero. Before starting, you tap the info icon — if RTP is disclosed by the provider, it appears there.
Open the game info panel on any Habanero title in the lobby. If the provider has disclosed RTP, the figure appears there.
On a BPL match page, the Asian handicap market removes the draw and gives one team a runs advantage. Read the line value before selecting — it determines the effective outcome you are backing, not just which team wins outright.
Before activating any offer, open the detail panel and locate the rollover figure. It tells you how many times the qualifying amount must be wagered. The games that count toward rollover are listed in the same panel — not all game types contribute equally.
After completing a bKash or Nagad deposit, the cashier screen displays a transaction ID. Your wallet app shows the same reference. Screenshot or note it — this is the first thing the support team asks for when you raise a payment query.
If a definition here still leaves a question — or if a term appears in your account and does not match what you expected — reach out through the support routes published on the site.
The live chat button is visible on the kt990 site when you are logged in. Open it, describe the term or screen you are asking about, and paste your transaction ID if the question is payment-related. The chat window is available from your account dashboard.
For detailed questions about a term's application to your account — particularly rollover conditions or KYC requirements — use the support email address listed in the Contact section of the site. Include your account username and the name of the offer or feature you are querying.
The Help section in your account contains published articles on payment terms, information conditions and KYC steps. Search the term you need there first — most common definitions and their account-specific context are covered in the articles already published.
These questions are about doing things in the platform, not just defining words — what happens when you act on a term you now understand.
Open the game's info or paytable panel before starting the round. If the provider has published RTP for that title, it appears there. If no figure is shown, the provider has not disclosed it — the lobby does not fill in estimates on their behalf.
Log into your account and open the Information or Bonus section. Information with a rollover requirement show a progress bar or counter tracking how much of the required wagering has been completed so far against the total needed.
Your deposit reaches the account balance normally. KYC affects withdrawals, not deposits. The account dashboard shows the verification status and tells you exactly which documents are still outstanding before a withdrawal can be processed.
Yes. The transaction history section in your account dashboard lists every deposit and withdrawal, including the payment method used and the transaction ID. Nagad transfers appear alongside bKash and other methods in the same chronological list.
High volatility means the round results are less predictable in short sessions — longer gaps between feature triggers are normal. The volatility rating in the game info panel is set by the provider, not adjusted by the platform, and applies uniformly to all players.
Navigate to the sportsbook section and open a cricket match page — BPL and international fixtures both carry Asian handicap lines when the market is available. The handicap value and odds sit directly on the fixture card inside the match panel.
