HOW WE RUN IT

Fair Play in Crash Zone

Provably Fair Rounds

Aviator and Crash Betboost use a provably fair system. Each round hash is published before the round starts, so you can verify the multiplier outcome independently after the round ends.

Studio Accountability

We carry crash titles from Spribe and Smartsoft Gaming, both of which publish their certification details. If RTP information is available from the provider, it appears on the game screen directly.

Live Multiplier Feed

Every player in an Aviator or Crash Betboost round sees the same multiplier climb in real time. The feed is not altered by individual bet size or account history — the outcome is shared.

Account-Level History

Your full crash round history — stake, cash-out multiplier and result — is stored in your account. You can review any past round at any time to cross-check against the published hash.

CRASH ZONE HELP

Help While You Play Crash Games

Team online

Round Disputes

If a cash-out tap did not register before the crash, contact live chat immediately with your round ID. Our team checks the server log for that specific round and responds with the outcome.

Account Wallet Sync

Crash rounds deduct and return funds to your account wallet in real time. If your balance looks off after a round, refresh your account page — most sync delays resolve within seconds.

Mobile Session Issues

If the multiplier feed freezes mid-round on your phone, the server still records your active cash-out instruction. Check your round history under your account to confirm the outcome.

399bay Inside the 399bay Crash Zone

Inside the 399bay Crash Zone

Crash Zone on 399bay runs titles from studios including Spribe and Smartsoft Gaming — providers whose crash mechanics are widely recognised. Aviator from Spribe is the headline title: a shared multiplier climbs until the plane flies off, and you cash out before that happens. Crash Betboost adds a faster-paced variant with a slightly different risk curve. Both games run on a provably

fair algorithm, meaning the round outcome is verifiable. You watch the same live multiplier feed as everyone else in the round, so there is no hidden information. Cash-out is a single tap — straightforward on any Android or iOS browser.

Crash Zone Terms You Should Know

What is a multiplier in a crash game?

The multiplier is a number that starts at 1x and climbs each round. Your payout equals your stake multiplied by the value at the moment you cash out, before the crash occurs.

What does cash-out mean in Aviator?

Cash-out is the action you take to lock in your current multiplier. You tap cash-out before the round ends; the game credits your stake times that multiplier to your account wallet instantly.

What is provably fair in crash games?

Provably fair means each round's outcome is generated using a published seed hash. After the round, you can use that hash to independently verify the crash point was not altered by the platform.

What is auto cash-out?

Auto cash-out lets you set a target multiplier in advance. The game cashes you out automatically when the live multiplier reaches that number, removing the need to tap manually mid-round.

What does bust or crash mean?

Bust or crash is the moment the round ends. The multiplier stops climbing, and any player who has not cashed out loses their stake for that round. There is no recovery after the crash point.

What is RTP in the context of crash games?

RTP (Return to Player) is the theoretical percentage of total stakes returned to players over many rounds. For crash titles, RTP is only shown on screen where the game provider publishes that figure.

Crash Zone Questions We Hear Most

The lobby currently features Aviator by Spribe and Crash Betboost. Both run as live multiplier rounds shared across all players. We add new crash titles as providers release them, so check back for updates.

Yes. Aviator and Crash Betboost run in your mobile browser on Android and iOS without needing a separate download. The cash-out button is sized for touchscreen use so it responds cleanly on a small screen.

Open your account wallet and select bKash, Nagad or Rocket as your payment method. Complete the transfer in your wallet app, and the balance updates so you can move straight into a crash round.

Stake limits for Aviator are shown on the game screen before each round starts. We do not override those limits — they are set by Spribe and apply consistently across all rounds in the lobby.

If you disconnect mid-round, the server records any active cash-out instruction you have already placed. Check your round history under your account after reconnecting — the result will be logged there.

Auto cash-out is available on mobile the same way it is on desktop. Set your target multiplier before the round starts, and the game handles the cash-out even if your screen goes to standby.
