From RTP and house edge to Upay wallet steps and rollover conditions, this glossary covers the language you encounter across our lobby, account pages and payment records.
A term like volatility looks technical until you realise it tells you how often a slot like Spice Bazaar Slots pays out versus how large each payout tends to be.
The glossary splits naturally into four groups. Each group lives in a specific part of the lobby or account area, so knowing which family a term belongs to tells you where to look for it in practice.
Terms like RTP, volatility, paylines and multiplier appear on individual game pages or inside the information panel. In slots such as Spice Bazaar Slots, the provider surfaces RTP only where the game engine exposes it — not every title shows a published figure.
Asian handicap, over/under, decimal odds and spread live inside the sportsbook section. Cricket Super Over and Football ChampionBets markets display these directly on the selection card before you confirm a stake. The number shown is the market price at that moment.
Deposit, withdrawal, e-wallet, KYC and pending balance appear in your account wallet tab. When you move funds via Upay or Bank Transfer, the transaction record uses these exact labels — so matching the term to the screen is straightforward once you know each definition.
Rollover, turnover requirement, qualifying stake and wagering period are the terms attached to any active information. They appear in the information detail panel inside your signed-in account area, not in the lobby tiles — read them before you activate anything.
These six terms come up in the slot lobby, live casino rooms and table games. Each definition is written to match exactly how the term behaves on screen.
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 platform holds on each game. It is expressed as a percentage of each stake. A lower house edge means more of your total wagering statistically returns to you across extended play.
Volatility describes how a slot distributes its payouts. High volatility means fewer wins but larger amounts when they land. Low volatility means more frequent smaller wins. It affects session pacing, not the overall RTP of the title.
A wager or turnover requirement is the total amount you must stake before a conditional balance can be withdrawn. It is stated as a multiplier of the qualifying amount and appears in the information terms inside your account.
Some slots accumulate a progressive prize pool fed by a fraction of each stake across all sessions. The current pool size is displayed on the game tile. It resets after a qualifying win combination triggers the prize round.
A live dealer is a real person dealing cards or spinning a wheel from a studio feed streamed directly to your screen. You see the action in real time and place bets through the game interface, the same as at a physical table.
These terms appear in the sportsbook markets, your payment records and the account verification flow. They are distinct from game mechanics and come up most often when you are depositing, withdrawing or reading a cricket market.
Asian handicap is a betting market format that removes the draw outcome by giving one team a virtual advantage or disadvantage. It is common in cricket and football markets and reduces the number of possible results to two.
Over/under is a market where you predict whether a measurable value — total runs in a cricket match, total goals — will finish above or below a line the platform sets. You choose one side; the line does not change after you confirm.
Rollover is another word for the wagering or turnover requirement attached to a conditional balance. It states how many times the relevant amount must be staked in qualifying games before a withdrawal of that balance is permitted.
An e-wallet is a mobile-based payment account — such as bKash, Nagad or Rocket — linked to your phone number rather than a bank card. Deposits and withdrawals route through the wallet's own transfer confirmation screen before reaching your ok50 balance.
KYC stands for Know Your Customer. It is the identity verification step the platform requires before processing withdrawal requests above certain thresholds. You upload the documents specified on the verification screen in your account settings tab.
Decimal odds show the total return per unit staked, including your original stake. A price of 2.50 means a one-unit stake returns 2.50 units if the selection wins. This format is the default display in the sportsbook on ok50.
Understanding terms in isolation is useful, but the practical payoff comes when several definitions work together in a single decision. Consider choosing between Crash Zap and Holdem Cutthroat.
The rising multiplier in Crash Zap is the game's core RTP expression. There is no payline structure; the house edge is embedded in the crash probability curve. RTP information appears only where the provider exposes it inside the game panel.
In Holdem Cutthroat, volatility is driven by hand matchups rather than a random-number generator spinning reels. Each decision point — fold, call, raise — affects the session outcome. The house edge comes from the ante structure, visible in the table rules.
After you submit a Bank Transfer withdrawal, your account shows a pending balance. That balance moves to cleared once KYC verification and bank processing complete. The exact step sequence is shown in your account transaction history, not in the lobby.
Cricket Super Over markets display decimal odds and over/under lines on the selection card. Odds shift with each delivery during live betting. The definitions of both formats above apply directly to what you see on that screen in real time.
If a definition here does not match what you see on a specific screen, the fastest resolution is to contact support directly with a screenshot of the term in context.
Start a live chat session from the help icon in the bottom navigation of the site. Describe the term and the screen where you saw it. The support agent can access your account context and clarify the definition as it applies to your session.
Send a message through the contact form in your account settings. Include the term in question and the section of the site where it appeared — for example, a information panel or a withdrawal screen. Written responses cover the full context.
The help centre inside your account contains published articles on payment steps, KYC documents and information conditions. Search the term directly in the help centre search bar before opening a support ticket — many definitions already have a dedicated article.
These questions are about how specific features work on ok50, not about the definitions themselves — those are covered above.
Open the information panel inside the slot title. RTP is shown there only when the studio — JDB, Spadegaming, PlayStar or Microgaming — publishes it for that specific title. Not every game exposes a figure, and we do not display estimated numbers.
Go to the information section inside your signed-in account area. Each information has a detail panel listing the rollover requirement, qualifying games, wagering period and any stake conditions. Read the full panel before placing qualifying bets.
Open the verification section in your account settings. The screen lists the documents required and their upload format. Submit exactly what is requested and then check the status indicator — your pending withdrawal moves forward once the check is marked complete.
Withdrawal routing depends on the payment method you used to deposit and the conditions in your account settings. Check the withdrawal screen in your wallet tab — it shows which payment options are currently available for your account at the time of the request.
The handicap line appears on the selection card next to each team. One side receives a virtual run advantage; the other concedes it. Your selection wins if the actual result, adjusted by the handicap, finishes in your favour by the close of play.
House edge is set by the game rules, not the delivery format. A live dealer version of Blackjack Livebets and a standard digital version using the same rule set
