The original Aviafly (not to be confused with Aviafly 2 from January 2026) came out of InOut Games studio on November 23rd, 2023, and pulled off something novel: two independent bet modes run in the same flight. While the plane climbs you have got two windows open - classic Cash Out riding the multiplier up, and a separate Trenball panel where you wager on whether the flight will finish above or below a specific threshold. It is a crash game and a prediction bet rolled into one round. The dual layer demands you juggle the climbing multiplier against the Trenball target at the same time, a different grade of attention than plain Aviator asks. Players who keep both plates spinning get to wring more angles out of a single round.

Aviafly by InOut Games is the original Aviafly title, released on 23 November 2023, not the 2026 sequel Aviafly 2. It ships a 95% RTP with a 5% house edge, a bet range that starts at €0.01 and climbs to €200 per round, a provably fair layer built on SHA-256 commit-reveal, and two gameplay modes most of the crash category does not carry. Classic Mode is the familiar crash loop with manual or auto cash-out. Trenball Mode is prediction-style: you lock in one or more of three fixed target multipliers (1.96x, 2x, 10x), and the bet auto-settles if the plane reaches the target. Dual-Mode Play lets you run both modes in the same round. Max payout tops out at x1,000 in Trenball, and the exact dollar-cap varies by operator.
The free Aviafly demo runs right here on this page - same RTP, same math, and both Classic and Trenball modes behaving exactly as they do in the paid client. The dual mode takes getting used to, and that is the exact reason to spend time here: watch how two bets resolve against each other, notice how your hand shifts between panels, get the hang of the mode's on-screen cues. Anyone coming from plain-vanilla Aviator usually fumbles the first few rounds, which is much cheaper to do in demo than on a live stake.
When luck is on your side, nothing kills the mood faster than a slow payout. Pick one of the casinos below and your win lands in your wallet within the hour.
The standout idea is that every round can be played in two modes at once. Classic Mode looks and feels exactly like the crash titles you already know: place a bet, watch the biplane climb, tap Cash Out before it leaves the frame. Trenball Mode runs alongside the Classic panel and works differently. Instead of hunting a live exit point, you pre-commit to one or more of three fixed target multipliers (1.96x, 2x, or 10x), and the bet auto-settles as a win the moment the plane passes that target in the round. If the plane crashes before, the Trenball stake is lost. No manual cashout is involved in Trenball, the math runs itself.
The three Trenball targets are not random numbers. 1.96x is the near-even-money target: a true 50% outcome at 100% RTP would pay exactly 2.00x, and Aviafly's 1.96x trims that by the 5% house edge (actually 0.95 / 0.485 ≈ 1.96), giving you the honest even-money bet with the margin visible. The 2x target sits just above, meaning the target hits about 47.5% of rounds at 95% RTP. The 10x target hits roughly 9.5% of rounds. You can stake any combination of the three in the same round and the outcomes are independent: 1.96x can win while 10x loses, each resolves on its own. This is binary-prediction mechanics grafted onto a crash loop, and it is the piece that no other crash game in our cohort ships.
"The 1.96x Trenball target is the mathematically honest even-money bet of the crash category. At 95% RTP, the fair payout for a 50% outcome is exactly 1.96x, and InOut exposes that number directly instead of hiding it under layered cashout mechanics. You see the house edge in the multiplier."
Aviafly is provably fair in the cryptographic sense. Before each round, the InOut server commits to a seed by publishing its SHA-256 hash, and after the round the seed is revealed along with the client contribution. Any player can feed the revealed seed back through SHA-256, match the commitment, and recompute the crash point independently. This is the trust primitive Aviator built the category on, and it is a cleaner tier than audit-only fairness models like the one Aero by Upgaming uses. The feedback panel inside Aviafly publishes every round's coefficient, outcome, and round ID on a transparent feed, so a session can be audited empirically in real time.
Classic and Trenball are not alternatives, they are lanes. The bet panel on Aviafly lets you stake the Classic side with a manual or auto cash-out, and simultaneously stake one, two, or all three Trenball targets with their own stakes. Every Trenball target settles independently, and the Classic bet settles independently too. In a single round you could, for example, stake €5 Classic with auto cash-out at 1.50x, plus €2 Trenball at 1.96x, plus €1 Trenball at 10x. The round then produces up to four distinct outcomes based on where the plane actually crashes. This is layered exposure no other cohort game offers, and it is the strongest strategic argument for Aviafly over a plainer crash cabinet.
At 95% RTP, the game ships a 5% house edge, and this is the honest weak point of the game. Aviator runs 97% (3% edge), Astronaut runs 98% (2% edge), Aero by Upgaming runs 95 to 95.9%, and Aero Turbo runs 88 to 96% sliding. Aviafly is at the lower end of the cohort on pure expected value, and across a thousand €10 rounds the expected loss on Aviafly is €500, compared to €300 on Aviator and €200 on Astronaut. The 2 to 3 percentage point gap is not trivial for grinders. What Aviafly offers back is the mode optionality: if the Trenball layer actually gives you a variance shape you like, the 5% cost buys a product no other cabinet sells.
InOut Games is a Curacao-licensed B2B studio (license 8048/JAZ2021-031) that focuses on crash and instant titles. The operator footprint is narrower than Spribe's but covers aggregator-distributed casinos across Europe, Latin America, and Asia. InOut also distributes Aviafly 2, the 2026 sequel that removes manual cashout, raises RTP to 96.5%, and caps at x100 multiplier. Do not confuse the two titles: Aviafly 2 is a different game with a different fairness layer and different mechanics, even though the brand is shared.
Open the game, confirm the 95% RTP in the info panel, decide which mode you want to stake: Classic Mode for manual or auto cash-out, Trenball Mode for one to three fixed prediction targets at 1.96x, 2x, or 10x, or Dual-Mode Play to stake both at once. Place the stake, watch the biplane climb, and either tap Cash Out in Classic mode before it leaves the frame, or let Trenball settle on its own.
Aviafly's free demo runs the exact client used for real money, with the same RNG and crash-point distribution. Every Trenball combination or Dual-Mode layout you rehearse in the demo behaves identically at the cash register, which makes it the correct tool to learn the twin-mode rhythm before committing a deposit.
Aviafly uses SHA-256 commit-reveal per round. Before bets close, the server publishes a hash of the server seed. After the round ends, the seed is revealed and any player can recompute the hash to verify the commit, then independently derive the crash point. The transparent coefficient feed inside the game publishes every round's outcome in real time, so a session can be audited empirically across dozens or hundreds of rounds.
Aviafly's fairness layer is built on the same primitive that made Aviator the category reference: a cryptographic commit-reveal sequence where the server seed is hashed with SHA-256 and the hash is published before bets close. After the round ends, the seed is revealed together with the client contribution, and any player who kept the published hash can verify that the commit matches and recompute the crash point by hand.
What SHA-256 provably fair does not protect against is the 5% house edge itself. The cryptographic layer confirms that the crash point was fixed before bets were seen and that it was not tampered with after the fact. It does not rewrite the underlying distribution. If InOut configures the distribution for a 5% edge at 95% RTP, the math will honestly return that 5% negative expected value, and every hex character of the hash will confirm that result. Provably fair is a trust guarantee, not an RTP guarantee.
Not rigged. Per-round SHA-256 commits and seed reveals let any player verify outcomes independently, and the transparent coefficient feed publishes every round's result in real time. The honest critique is not rigging, it is the 5% house edge (95% RTP), which is the lowest in our cohort on pure expected value. The game is mechanically honest; whether it is the best value among crash cabinets is a separate question with a clear answer: no, unless you specifically want Trenball.
The useful criticism of Aviafly is not about rigging. It is about expected value. The game is mechanically honest, cryptographically transparent, and operates under a valid license. What it costs you is a 5% house edge, which is one percentage point worse than Aviator and three points worse than Astronaut. If you play for the Trenball mode or the Dual-Mode Play, that cost may be worth it. If you play for the cheapest expected loss in the crash category, it is not the right pick.
Most crash cabinets ship a dual-bet layout where you can place two independent stakes on the same round, each with its own cash-out target. Aviafly does ship that, but it also ships something more unusual: Dual-Mode Play, where the Classic crash bet and one or more Trenball prediction bets run simultaneously in the same round. The two modes resolve independently, and the combination creates a layered exposure profile no plain Dual Bet can match.
Dual-Mode Play changes the variance profile of a crash session without changing the expected value: the 5% house edge still applies to every stake you place on every lane. What the dual-mode setup gives you is a cleaner separation between defensive and speculative plays, and the Trenball targets specifically give you a self-settling binary outcome without needing the timing of a manual cashout. If you already use Dual Bet on Aviator or Two Bets on Aero, the closest analogue to Aviafly's Dual-Mode is running two Classic-mode stakes, but the Trenball layer is genuinely new and has no direct equivalent anywhere in the cohort.
At 95% RTP the crash-point distribution follows approximately 0.95/m: 2x lands in ~47.5% of rounds, 5x in ~19%, 10x in ~9.5%. The Trenball targets (1.96x, 2x, 10x) track this distribution directly, and their published hit rates can be cross-checked against the transparent coefficient feed during a live session.
Crash-point distributions in Aviafly follow the same geometric shape every modern crash cabinet uses, with the scale factor pinned to the shipped RTP. For Aviafly's 95% RTP, the formula is approximately 0.95 / m. The table below shows where the key targets land, including the three Trenball prediction levels built into the cabinet.
| Target multiplier | Probability to reach | What it means in 100 rounds |
|---|---|---|
| 1.00x | ~5% (insta-crash) | About 5 rounds in 100 fold instantly before Classic-mode Cash Out is practical. That is the 5% house edge at 95% RTP, visible directly in the distribution. |
| 1.20x | ~79.2% | About 79 rounds in 100 reach this target. Conservative Classic-mode auto-target, though even at this rate the 5% edge eventually wins out over a long session. |
| 1.50x | ~63.3% | Nearly two-thirds of rounds reach 1.50x. Classic Auto Cash-Out sweet spot that balances hit rate and return. |
| 1.96x | ~48.5% | First Trenball target. This is the mathematically fair even-money bet at 95% RTP. Hits just under half of rounds, settles automatically when the plane passes 1.96x. |
| 2.00x | ~47.5% | Second Trenball target. Just above 1.96x but with slightly lower hit rate. 2x is not a coin flip; the 5% edge eats the missing 2.5% you would need from a true 50%. |
| 5.00x | ~19.0% | About one round in five. Classic-mode stretch target. Dry streaks of 10 or more misses are routine and must be budgeted into any bankroll plan. |
| 10.00x | ~9.5% | Third Trenball target. About 1 in 10 rounds lands the 10x auto-settle. High-variance lane, expect gaps of 20 or 30 rounds between hits. |
| 100x | ~0.95% | One round in 105 roughly. Lottery-ticket category. Treat multi-hundred Classic-mode auto-targets as entertainment, not strategy. |
| 1,000x | ~0.095% | One in a thousand. The Trenball max payout ceiling sits here as a theoretical cap; in practice the dollar-cap at your operator bounds it before a raw 1,000x Classic hit matters. |
Aviafly's distribution is a full percentage point worse across every target than Aviator at 97% RTP, and three points worse than Astronaut at 98%. What the distribution gives back is direct exposure to the Trenball targets: 1.96x pays out at the honest fair-even-money rate, 10x pays out at the honest ~9.5% rate, and both can be staked alongside a Classic auto cash-out in the same round. The distribution is identical to the rest of the crash category; what is unique is the binary Trenball exit points layered on top.
Aviafly's strategic interest is not in Classic-mode cashout timing (that is the same decision you make in every crash cabinet) but in how you allocate stake between Classic and Trenball lanes. The three cleanest approaches are: pure Classic grind at 1.2x to 1.5x, Trenball-only on the 1.96x target for disciplined binary play, or Dual-Mode combining a Classic auto-cashout with one or more Trenball targets. None beats the 5% edge, they just reshape your variance.
The ranking that matters is: if you want the cheapest expected loss, switch cabinet. Aviator at 97% or Astronaut at 98% both beat Aviafly's 95% before any strategic decision is made. The reason to play Aviafly is the Trenball layer specifically, which no other cohort cabinet offers. Pure Classic grinding on Aviafly is strictly worse than the same grind on Aviator or Astronaut. Trenball-only or Dual-Mode Play are the strategic cases where Aviafly's cost is justified by a product no other crash game sells.

Captures taken from the InOut Games demo client.
95% theoretical. InOut Games publishes this on its provider materials and the game's in-panel info confirms it. The RTP is flat across the full €0.01 to €200 stake range; there is no stake-size sliding scale like Aero Turbo. Over a thousand €10 rounds the expected loss on Aviafly is €500, compared to €300 on Aviator at 97% RTP and €200 on Astronaut at 98%.
Yes. Aviafly uses SHA-256 commit-reveal per round. Before bets close, the server publishes a hash of the server seed. After the round ends, the seed is revealed along with the client contribution. Any player can recompute the hash and verify that it matches the commit, then independently derive the crash point. The cabinet also publishes a transparent coefficient feed showing every round's outcome and round ID in real time.
No. Aviafly (this page) was released on 23 November 2023 with a 95% RTP, Classic Mode manual cashout, Trenball prediction targets, and Dual-Mode Play. Aviafly 2 was released on 27 January 2026 by the same studio, runs a 96.5% RTP, has no manual cash-out (fixed trajectory), and caps multipliers at x100. Same brand, different games. Check the game tile label before you stake.
Trenball is a prediction layer built into Aviafly. Instead of hunting a live cash-out point, you pre-commit to one or more of three fixed target multipliers: 1.96x, 2x, or 10x. Each target has its own stake and settles independently: you win if the plane passes it, you lose if the plane crashes first. No manual cashout is involved, and you can combine all three targets in the same round.
1.96x is the mathematically fair even-money payout at 95% RTP. At 100% RTP a true 50% outcome would pay exactly 2.00x; Aviafly's 1.96x trims that by the 5% house edge (0.95 / 0.485 ≈ 1.96), so the target is an honest binary bet with the margin visible in the number itself. The 2x target sits just above and hits about 47.5% of rounds. Both are offered so players can pick the level of rounding comfort they prefer.
The Trenball mode caps at x1,000 multiplier on the stake. With the €200 max bet, that is a €200,000 theoretical payout, but the practical dollar cap is set per operator and is typically much lower. Check your casino's payout terms before planning a session around the Trenball ceiling. Classic Mode has no fixed multiplier cap by design but is dollar-bound by the same operator-level payout rules.
Aviator has a higher RTP (97% vs 95%), a much larger operator footprint, and a six-year public track record. Aviafly has the Trenball prediction layer, Dual-Mode Play, a €0.01 minimum stake (vs Aviator's $0.10), and an in-game transparent coefficient feed. If you want the cheapest grinder cabinet, Aviator wins. If you want the prediction-layered cabinet no other game ships, Aviafly is the only choice.
Yes. InOut Games hosts a free demo of Aviafly on its studio portal and mirrors it through partner aggregators. The demo runs the exact client used for real money, with the same RNG and crash-point distribution. Every Classic cashout decision, Trenball target combination, or Dual-Mode layout you rehearse in the demo behaves identically at the cash register, which makes it the right place to learn the twin-mode rhythm before committing a deposit.
