From RTP and house edge to bKash wallet credits and KYC verification, this glossary covers the exact language you will see inside the 123k lobby, your account dashboard and the cashier screen. Each definition is written for how the term actually shows up on your screen — not how a textbook describes it.
These six terms appear on almost every game screen, lobby label and paytable inside 123k. Understanding them helps you read what a game is telling you before you commit a stake.
RTP stands for Return to Player — the percentage of total stakes a game returns over many rounds. A 96% RTP means the game pays back 96 units per 100 wagered on average over a very large number of spins. 123k shows RTP only where the game provider publishes it.
House edge is the built-in mathematical advantage a game holds over the player. It is the mirror of RTP carries a 4% house edge.
Volatility describes how a slot distributes its payouts. High-volatility slots pay larger amounts less often. Low-volatility slots pay smaller amounts more frequently. The game's information screen, where shown, lists its volatility tier — check there before you start.
A wager or turnover requirement is the total bet volume you must reach before a credited amount can be withdrawn. For example, a 10x requirement on a 500 BDT credit means placing 5,000 BDT in qualifying bets. The exact multiplier is shown in the relevant account terms.
A jackpot is the highest prize a slot or game can award, typically triggered by a rare symbol combination or a dedicated bonus round. The jackpot type — fixed or progressive — and its current value are displayed inside the game where the provider exposes that data.
A live dealer game streams a real human dealer operating physical cards or a roulette wheel from a studio. You see the action via video and place bets on your screen. Results are determined by the physical outcome, not a random number generator.
These terms come up most often when you are reading a sportsbook market, moving funds through bKash or Nagad, or completing an account verification step. Each definition maps to a screen or action you will actually encounter.
Asian handicap removes the draw outcome from a football or cricket match by giving one side a fractional goal or run advantage. A -0. 5 handicap means that team must win outright for your bet to pay. The exact lines are shown in the sportsbook market at the time of betting.
Over/under is a market where you bet on whether a measurable match statistic — total runs, total goals — will finish above or below a number set by the sportsbook. The line and the odds for each side are displayed on the event page before you confirm the bet.
Rollover is another word for the turnover or wagering requirement attached to a credited amount. Until the rollover figure is met, the credited balance sits in a pending state. Your account dashboard shows current rollover progress after login, updated as qualifying bets settle.
An e-wallet is a mobile money account — bKash, Nagad or Rocket — used to move funds between your phone balance and your 123k account wallet. The deposit screen lists the supported e-wallets and the steps needed to complete a transfer from each one.
KYC stands for Know Your Customer — the identity verification process that confirms your account belongs to you. 123k may request a national ID or a document showing your registered mobile number. The account section shows which documents are needed and the current status of your verification.
RNG stands for Random Number Generator — the software engine that determines outcomes in virtual slots, virtual table games and crash-style titles. Games using RNG do not rely on physical equipment. Live dealer games do not use RNG; outcomes there depend on the physical cards or wheel.
Knowing a definition is one thing; seeing where it appears during an actual session is where it becomes useful. When you open Roulette Spinners, the game info panel shows the RTP the provider has published — that figure, combined with the volatility tier, tells you what kind of session rhythm to expect before your first bet lands. In Aviator Sky Run, the multiplier rising on screen is not an RNG outcome in the slot sense — it is a crash mechanic, and understanding that distinction matters when you read the game rules tab.
The game information tab inside Roulette Spinners displays the RTP figure the provider has submitted. European and American variants carry different house edges — the rules tab names which variant you are playing.
Aviator Sky Run uses a crash multiplier format, not a reel-spin RNG. The distinction affects how you read volatility: there is no paytable, only a rising multiplier you cash out before it resets.
After a bKash deposit, the cashier screen logs the transferred amount, the wallet credit and any pending rollover as separate rows. This is the record to reference if you contact support about a balance question.
The match card in Football StrikeZone displays Asian handicap and over/under markets in adjacent columns. Each column shows the current line and decimal odds — the glossary terms map one-to-one with these screen labels.
If a glossary term appears on your screen and the definition here does not fully explain what you are seeing in that specific game or cashier state, the support team can walk through it with you using your actual account data — not a generic example.
Start a live chat session from any page inside your logged-in account. Share the screen label or term you are uncertain about and the agent can check the relevant game or transaction record directly against your account.
Your account dashboard after login shows the current state of your wallet balance, any pending rollover, transaction history and verification status — the primary place to check before contacting support about a term you have seen in the cashier.
For questions about KYC document requirements or a specific wager calculation you cannot resolve through the dashboard, email support allows you to attach screenshots of the transaction or game screen for a detailed written response.
A player who understands RTP, volatility and rollover makes different choices than one who does not. Picking between Baccarat Speeddial and a high-volatility slot is not just a preference call — it is a decision about session length, stake sizing and when a withdrawal makes sense. The same logic applies to payments: knowing what KYC means before you attempt a Nagad withdrawal removes the friction of an unexpected verification step. Account controls like spending history and transaction records become more useful once you can read what each line item is telling you. This glossary is not an exhaustive dictionary — it covers the terms that directly affect account decisions, lobby navigation and cashier actions on 123k. Where a term depends on a specific provider's implementation, the game's own information panel is the authoritative source.
The lobby, cashier, sportsbook and account settings each surface a different cluster of terminology. This map shows which group of terms belongs to which part of the platform so you know where to look when a label needs clarifying.
RTP, volatility, house edge, RNG, bonus round and jackpot all appear inside individual game information panels or paytables. Open the rules or info tab within any slot or table game — Roulette Spinners or Baccarat Speeddial, for example — to find these figures where the provider has published them.
Asian handicap, over/under, decimal odds and match lines appear on the sportsbook event pages. Cricket and football markets, including BPL fixtures shown on Football StrikeZone, display these labels directly on the bet card before confirmation — no separate menu needed.
E-wallet, deposit, withdrawal, transfer and transaction record are the terms you see in the cashier screen. Each bKash, Nagad or Rocket transaction generates a separate row in your transaction history, with amount, method and status shown as distinct fields.
Rollover, turnover, wagering requirement, eligible games and expiry date all appear on the account dashboard under any active credit conditions. These terms describe what must happen before a credited amount converts to withdrawable funds — the dashboard shows progress in real time after login.
These questions are about applying glossary knowledge to specific platform actions — finding a setting, reading a screen or completing a process — rather than asking for a definition.
Open the slot, then look for the information or rules icon — usually a small 'i' or a question mark inside the game frame. The RTP figure appears there if the studio has published it. Not every title displays this; CQ9 and Habanero games typically include it in their rules panel.
Log in and open your account dashboard. The active balance section shows the credited amount, the wagering requirement multiplier and the current progress figure as separate line items. The display updates as qualifying bets are settled across eligible game categories.
An unverified account may have withdrawal restrictions until KYC steps are complete. The exact restrictions depend on your account status, shown in the verification section after login. Completing the required document submission removes the hold on the withdrawal path.
Yes. The transaction history tab in the cashier records every Nagad deposit and withdrawal as a separate entry with date, amount and processing status. If a transaction shows a status you do not recognise, that is the right record to reference when you contact live chat.
On the Football StrikeZone event page, the handicap line is shown as a positive or negative number next to each team. Select the line to see the decimal odds attached. The bet slip then displays the handicap value alongside your stake before you confirm.
Pragmatic Play and JDB games typically display a volatility indicator — shown as a bar graphic or a tier label such as high, medium or low — inside the game's information screen. Access it from the lobby before launching the game or from the rules tab once the game loads.
