Whether you are reading a game paytable, checking your account wallet, or placing a cricket market, this glossary gives you the plain-language meaning of every term you encounter across h31bdt — from game mechanics to payment language and account conditions. Start with a category below or read straight through.
A term you don't recognise on a paytable or account screen can cost you a decision. When you know what volatility means, you pick the right slot session length. When you understand rollover, you know exactly what a promo condition asks of you before you accept it.
Terms cluster around four areas of the platform. Knowing which area a term belongs to tells you where to look for it and what action it relates to.
RTP, volatility, paylines, multiplier, RNG — you see these on individual slot or table game detail screens. They describe how a game pays, how often it pays, and how the outcome is generated. Check the game info panel for any title from Spadegaming, Habanero or CQ9.
Asian handicap, over/under, decimal odds, spread, match line — these appear on sports market boards, especially cricket and football. Each format changes how you read a price and how your return is calculated. The market board displays the active format for each event.
E-wallet, mobile wallet, Bank Transfer, withdrawal hold, pending balance — these appear in your account wallet section. Nagad and Upay transactions each follow the steps shown in the payment screen at the time you initiate a transfer. Your transaction history logs each movement.
Rollover, turnover requirement, qualifying bet, minimum odds — these appear inside the terms attached to any active information. Before accepting a promo offer, open the full conditions panel where the rollover figure and qualifying market rules are set out clearly.
These six terms appear most often when you open a slot, table game or live dealer session. Read each definition once and you will recognise them everywhere.
RTP stands for Return to Player. It is the theoretical percentage of wagered money a game pays back over a very large number of rounds. A game with 96% RTP returns 96 taka per 100 wagered on average across all sessions — it is a long-run statistical measure, not a per-sess
House edge is the mathematical advantage the platform holds over the player across a game type. It is the inverse of RTP game has a 4% house edge. It does not predict individual session outcomes — it describes the long-run probability built into the game's design by its provider.
Volatility, also called variance, describes how frequently a slot pays and how large those payouts tend to be. High-volatility slots pay out less often but with larger amounts when they do.
A wager or turnover requirement is the total amount you must bet before a promo balance or conditional credit becomes withdrawable. For example, a turnover condition specifies how many times the promo amount must be placed across qualifying games or markets before the funds clear to your main wallet.
In slots, jackpot refers to the highest prize-tier available within that specific game's feature structure. Some games include a fixed jackpot ceiling; others use a progressive pool that accumulates with play. The jackpot rules are set by the game provider and shown in the paytable inside the game itself.
A live dealer game streams a real human dealer conducting table game rounds — baccarat, roulette or blackjack — from a studio feed.
These six terms come up when you are navigating sports markets, moving funds through Nagad or Upay, or managing your account verification status. Each definition is written for how the term appears on this platform specifically.
Asian handicap is a betting market format that removes the draw outcome by giving one team a goal or run advantage before the event starts. It is common in cricket and football markets.
Over/under is a market where you predict whether a combined total — runs in cricket, goals in football, or another measurable stat — will finish above or below a number set by the market.
Rollover is effectively the same as a turnover requirement: the number of times a credited amount must be bet through qualifying markets before withdrawal conditions are met.
An e-wallet or mobile wallet refers to a phone-linked payment account — Nagad, Upay or Bank Transfer — used to move funds to and from your h31bdt account wallet. Each transfer follows the steps shown on the payment screen. Your account page records every transaction with a status and reference number.
KYC stands for Know Your Customer. It is an identity verification process where you submit documents confirming who you are. On h31bdt, the KYC steps are shown inside your account settings.
A withdrawal hold means funds have been requested but are not yet released to your payment method. A pending balance is the amount sitting in this state.
Terms rarely appear alone — they connect across a session. When you open Crash Rocket from the lobby, the game screen shows a multiplier that climbs until the round ends.
The rising multiplier on the Crash Rocket screen is a live game-mechanic term made visible. Your settled return appears in your account wallet immediately after you confirm the cash-out action.
An Asian handicap line next to decimal odds on a BPL market board uses two odds terms simultaneously. Reading both tells you the outcome scope and the return on a correct prediction before you place.
When a Habanero title shows RTP and volatility in its info panel, both figures together inform session planning. High volatility plus a stated RTP means longer gaps between payout rounds — useful context for your wallet budget.
Inside the promo conditions panel, rollover and minimum odds appear as a pair. Rollover sets your wagering target; minimum odds filter which markets count. Checking both before accepting prevents a condition you did not expect.
If a definition here does not fully answer what you see on a specific screen — a payment status you don't recognise, a game condition that looks different in practice, or an account step that is unclear — reach out through the routes available on the site.
The live chat route is accessible from the account area and the main navigation. Use it when a term appears on a screen in a way that differs from what you expected, or when a payment s
The Help Centre contains articles covering account verification steps, wallet actions for Nagad and Upay, and promo condition explanations. Search by term or browse by category. Each article links to the account screen where the action takes place so you can follow along directly.
Your account notification panel records status updates on withdrawals, KYC requests and active promo conditions. If a term appears there — such as a hold reason or a verification request — the notification usually contains a link to the relevant account step or published condition.
These questions go beyond the definitions and cover how the features those terms describe actually work when you are logged in and active on h31bdt.
Open the game detail panel inside the lobby — look for an info or paytable icon on the game tile before you launch it. RTP is shown there only if the game provider has made it available.
Go to your information section and open the full terms for the information. The rollover multiplier, qualifying markets and any minimum odds are listed in that panel. The progress toward completing the rollover is also tracked in the same section while the promo is running.
A hold pauses the release of funds to your Nagad or Upay account while a condition is checked — usually a KYC step or a rollover balance.
Open the cricket section of the sportsbook and select a live or upcoming match. Markets are grouped by type; Asian handicap is listed alongside standard match-line and over/under options.
Yes — open each title's info panel in the lobby to compare the volatility rating and any visible RTP figure side by side. A high-volatility title from CQ9 or PlayStar suits a session where you are comfortable with less frequent returns; a lower-volatility option suits shorter, more predictable sessions.
KYC requests appear in the notifications panel and in your account settings under the verification section. The request specifies which documents are needed and what format to upload.
