Aviator is a crash-style game where a multiplier climbs from 1x and you cash out before it stops — the longer you wait, the higher the potential multiplier, but the round can end at any point.
Aviator belongs to the crash-game category — a format where the outcome is determined by a rising multiplier rather than spinning reels or card draws.
Aviator gives you more manual control than most casino formats. Before a round begins you set your stake, and once the plane is airborne the only decision left is when to press cash out.
Before each round opens, you type or adjust your bet amount in the stake field. The minimum and maximum values are shown inside the game screen next to the input box. Your 99hb account balance must cover the stake before the round starts or the bet will not register.
Set a target multiplier in the auto cash-out field and the game will exit your position automatically when that number is reached.
Aviator lets you run two separate bets in the same round using the side-by-side bet panels. Each panel has its own stake and its own auto cash-out field, so you can hold one conservative exit target and one higher one simultaneously within a single round.
The rising number on screen is the current round multiplier. When you cash out, your return equals stake multiplied by that figure.
Crash games like Aviator typically publish a theoretical return-to-player figure and a provably fair mechanism in the game's own information panel rather than on the lobby page.
Tap the information or question-mark icon inside the Aviator game screen to open the published rules, theoretical return rate and fairness documentation. This is the provider-sourced version of the data — read it before placing stakes so you understand the house edge the game operates on.
Each Aviator round generates a verifiable seed hash that is displayed before the round begins. After the round closes you can check the result against the seed using the method described in the game
The column running along the side of the game screen lists the multiplier result of every completed round during your session. Scroll through it to see the distribution of recent outcomes. The game does not imply any pattern prediction from this data — it is a record, not a forecast tool.
Aviator loads in a mobile browser without a separate download. Open 99hb in Chrome or Safari on your phone, navigate to the casino section, and search for Aviator in the lobby.
Most Aviator questions come up mid-session — a disconnection during a round, a stake that did not register correctly, or a cash-out result that looks unexpected. The routes below are the ones we publish on the site.
Open the chat widget from the site footer while the game is still on screen. Describe the round ID and the issue — our team can review the session log and confirm what the server recorded. Use this route for any in-round dispute.
Every settled Aviator round is recorded in your account's transaction history. Log in, open the wallet or history section, and filter by the date and time of the round in question. This is the first place to check if a cash-out result seems different from what you saw on screen.
For issues that need a written record — such as a disputed round result or a wallet credit not reflecting — send the details to the support email address shown on the Contact page. Include your account username, the round time and the multiplier value you expected to receive.
Crash games operate on disclosed mechanics, and Aviator publishes its core data inside the game screen rather than hiding it behind external links.
The theoretical return percentage for Aviator is available in the in-information panel. Open it from the icon inside the game window. The figure shown there is provider-sourced — we display it as-is and do not modify or supplement it with a different number on the lobby page.
Each round's seed is published before the plane takes off. After the round ends, the reveal appears in the fairness section of the game.
Aviator is found by opening the casino section of the 99hb lobby and using the search field or the crash-games filter. The category label it appears under confirms the game format.
Your account history logs each Aviator round, the stake placed, the multiplier at cash-out and the return credited. Open the history or wallet section after your session to cross-check what the game screen showed against what was settled. Discrepancies can be flagged through live chat with the round ID attached.
Aviator uses a small set of terms that are specific to the crash-game format. If you have come from slots or live tables, some of these will be new. The definitions below explain each term plainly so you know exactly what the game screen is showing you.
The multiplier is the rising number on screen during a live round. When you cash out, your stake is multiplied by this figure to calculate your return. A multiplier of 2.50x on a 100 BDT stake returns 250 BDT before the round ends.
The crash point is the multiplier value at which a round ends. If the crash point is 1.40x and you have not cashed out yet, your stake is lost. The crash point for each completed round is shown in the round history column on the game screen.
Provably fair means the round result is generated from a cryptographic seed that is committed before the round starts and revealed after. You can verify that the crash point was not altered mid-round. Aviator publishes this seed and its verification method inside the game's fairness panel.
Auto cash-out is a preset multiplier target you enter before the round begins. The game exits your position automatically when the multiplier reaches that value. If the round crashes below your target, the stake is not recovered — the auto feature does not prevent a loss.
RTP stands for Return to Player — the theoretical percentage of total stakes returned as winnings over a large number of rounds. Aviator's RTP figure is published in the in-information panel by the provider; we do not state a figure independently on this page.
The round history is the scrollable log of recent crash-point results shown alongside the game screen. It is a transparency record of how past rounds settled. It does not predict future crash points and should not be used as a strategy reference — each round result is independent.
The questions below come from account holders who have moved from sports betting or slots into Aviator for the first time. Each answer reflects what the game screen and account area actually show — no invented figures or implied guarantees.
No separate account is needed. The same login you use for cricket markets and slots opens Aviator directly.
Aviator runs inside a mobile browser without a separate download. Open 99hb in Chrome or Safari on your Android or iOS device, log in, and navigate to the casino section.
If your connection drops mid-round and you had an auto cash-out target set, the game will attempt to execute it on the server side. If no auto target was set, the round is settled at the crash point without your input.
Log into your 99hb account, open the wallet or deposit section, and select bKash from the payment options shown there.
The minimum stake for Aviator is shown inside the game screen next to the bet input field — it is set by the game provider and may differ from stake floors on slots or table games.
Open the game screen and look for the information icon, usually positioned in a corner of the interface. Tapping it brings up the provider's published rules, the theoretical return rate and the provably fair verification method.
