Every term you see in the ob666 lobby — from wagering conditions to live dealer rules — is defined here in plain English so you can make sharper decisions on every session.
When you know what RTP and house edge mean, you can pick a slot or table that matches how you want to spend a session. When you understand wagering conditions, you know exactly what a information requires before a withdrawal becomes available. The terms in this glossary appear across the ob666 lobby — in game panels, the cashier screen, account settings and the promo board.
Terms like RTP, house edge, volatility and RNG appear inside the game panel or on the game detail card. Open any slot from Microgaming, JDB or Spadegaming and check the information tab — those figures are displayed there where the provider makes them available.
Asian handicap, over/under, decimal odds and match handicap live in the sportsbook section. Cricket markets — including IPL and BPL match lines — are labelled using standard odds formats. Knowing the difference between decimal and fractional odds stops misreads on live lines.
Balance, withdrawable amount, pending transaction, KYC verification and e-wallet routing show up in the cashier and account screens. Your Nagad or Rocket transfer moves through these states in sequence; the cashier screen labels each one so you can track where a transaction sits.
Rollover, turnover multiple, contribution rate and expiry clock are the four terms that govern every information on the promo board. Before you opt in, the terms panel shows these figures — read the rollover figure and the game contribution rate together to plan your sessions accurately.
RTP is the percentage of all wagers a slot or game returns to players over a very large number of rounds. A 96% RTP means the game returns 96 units on average for every 100 wagered over its statistical lifetime. Individual sessions vary widely.
House edge is the mathematical advantage the game holds over players, expressed as a percentage of each wager. A house edge of 2.7% on roulette means the game expects to keep 2.70 units from every 100 wagered across all rounds statistically.
Volatility describes how a slot distributes its payouts. High-volatility slots pay less often but in larger amounts when they do hit. Low-volatility slots pay smaller amounts more frequently. Your session bankroll and session length both affect which suits you.
A wager or turnover requirement is the total bet amount you must place before a bonus balance or restricted withdrawal becomes available. It is shown as a multiple — for example, a 20x requirement on a 500 taka credit means 10,000 taka in qualifying bets.
In slot terms, a jackpot is the highest prize-level feature built into the game mechanics, triggered by specific symbol combinations or random events. The size and trigger conditions are set by the game provider and shown in the paytable inside the game panel.
A live dealer game streams a real croupier running a physical table — baccarat, roulette or blackjack — to your device in real time. You place bets on the same interface as standard casino games, but results come from the physical cards or wheel rather than an RNG.
Asian handicap removes the draw outcome by giving one team a goal or run advantage before the match starts. A -1.5 handicap on the favourite means they need to win by two or more for a winning bet. It is common on cricket and football markets.
Over/under is a market where you bet on whether a combined figure — total runs in cricket, total goals in football — will be above or below a line set before the event. Your prediction is on the total, not on which side wins.
Rollover is the number of times you must bet the information amount before any associated winnings can be withdrawn. A 10x rollover on a 200 taka credit means you need 2,000 taka in completed bets before withdrawal eligibility opens in your account.
An e-wallet is a mobile payment account — bKash, Nagad or Rocket — that acts as the transfer point between your bank or phone balance and your ob666 account wallet. Deposits and withdrawals route through the e-wallet number you register in the cashier.
KYC stands for Know Your Customer. It is the identity verification step your account may require before a withdrawal is processed. The cashier screen shows what documents or confirmation steps are pending; completing them clears the restriction on your withdrawable balance.
Session controls are account-level settings that let you manage how long or how much you play in a period. They include deposit amount limits and cool-off periods. These are set through your account settings page and take effect as specified in the policy shown there.
Seeing terms in isolation is one thing; the moment they interact, decisions sharpen. When you open a slot from Bigtime Gaming or Joker and check the information tab, you are reading volatility and RTP will behave very differently across a short session compared to a low-volatility title at 96.5%. Neither is wrong; they suit different session goals.
High-volatility slots from Spadegaming or Microgaming are better suited to a longer session with a larger starting balance because the gap between feature triggers is wider. Check the information tab for the volatility label before you start.
BPL and international cricket markets on the sportsbook use Asian handicap with run-based lines. The handicap figure sits beside the team name; a negative figure means that team gives runs, a positive figure means they receive them.
After activating a information, the account panel shows your real-time progress toward the rollover target. Each qualifying bet on an eligible game — check the contribution rate in the information terms — moves the meter. Non-eligible games do not contribute.
A Nagad deposit moves through initiated, pending and confirmed states in the cashier. The transition from pending to confirmed depends on the Nagad network completing the transfer; the cashier screen updates automatically and your balance reflects the confirmed amount.
If a term in the lobby, the cashier or the promo board is not covered here or still reads ambiguously, use the contact routes below. Our support team handles account and game-terminology questions for Bangladesh members.
Open the chat widget from the account area or the lobby footer to ask about a specific term or screen. Available through the site for members in supported regions.
Send a message through the contact form in the account area if your question covers a withdrawal state, a KYC step or a information condition you want clarified before acting.
The help and policy section linked from the account menu covers account controls, cashier steps and information conditions in structured form — a useful first stop before contacting support.
RTP is shown inside the game's own information panel, accessible from the game tile before you open it or from the menu inside the game. RTP figures are displayed only where the game provider makes them available — not all titles publish this figure in the panel.
Log into your account and open the information or information section. Active information display a turnover meter showing bets completed against the target. Only bets on eligible games at the contribution rate shown in the information terms count toward the total.
After completing a Rocket transfer, the cashier screen shows the deposit in a pending state first. Once the Rocket network confirms the transfer, the status updates to confirmed and the amount appears in your available balance, ready for the lobby.
Setting an account deposit limit restricts how much can be deposited within the period you choose. Bets and withdrawals from your existing balance continue normally. The limit applies only to incoming deposits and is visible in your account settings once active.
Live dealer tables, including baccarat and live cricket-themed tables in the lobby, load through a mobile browser on Android and iOS without requiring a separate app download. The lobby detects your device and adjusts the table layout accordingly for mobile screens.
The information terms panel — accessible by tapping the information detail before opting in — lists eligible game categories and the contribution rate for each. Slots from Microgaming, JDB and Spadegaming typically appear in the eligible list; check the specific information for the rates that apply.
