Aviafly (InOut Games): 95% RTP Classic-vs-Trenball crash review
Want a crash game with two stakes per round running on different rules? Aviafly from InOut Games (November 2023) ships exactly that - classic Cash Out riding the multiplier alongside a Trenball panel betting on flight thresholds. It is a crash and a prediction bet rolled into one round, and the dual layer rewards split-attention play. Not for click-and-cash novices.

The free Aviafly demo runs right here - 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.

Aviafly breakdown: Classic plus Trenball, 95% RTP, InOut's twist on crash
Two modes, two playstyles
Want a crash game with multiple gameplay modes baked in? Aviafly from InOut Games ships two: Classic (standard aviation crash) and Trenball (a twist where you pick "over/under" on a target multiplier). Same RTP, two completely different decision loops.
Classic mode plays like Aviator: a plane climbs, multiplier ticks, you hit cash out. Trenball mode is closer to sports betting - pick over or under a chosen number, the round resolves, you win or lose. Two games for the price of one game license.
RTP 95% and the budget tradeoff
Aviafly runs 95% RTP across both modes - two percentage points below Aviator. House edge 5%. That's the price of the dual-mode flexibility and the wider bet range (up to EUR 200 per round). Calculate your hit probability.
If you only ever play Classic mode, you're getting Aviator's mechanic at 95% RTP - a worse deal than Aviator at 97%. If you actually use Trenball mode, the dual-game value justifies the lower RTP. Most players don't use Trenball after the first session, which is the catch.
"Aviafly's Trenball mode is a clever idea executed cleanly, but it asks players to think about over/under bets when they came for crash. Most reset to Classic and never come back."
Trenball mode walkthrough
Curious how Trenball actually works? You pick a target multiplier (say 2x) and bet either "over" or "under" before the round starts. The round runs, the crash point is revealed, your bet wins if the crash point matches your direction. House sets the odds based on the implied probability of each direction.
It's mathematically equivalent to a flat-RTP crash with auto-cashout, except you can't change your decision mid-round. Less skill expression, same expected value.
- Two modes (Classic + Trenball) in one game
- Bet range up to EUR 200 - wider than Aviator's $100
- x1,000 multiplier cap on Trenball
- InOut Games Curacao + iTech Labs audit
- RTP 95% trails Aviator (97%) and Astronaut (98%)
- Trenball mode rarely used after first session
- Smaller community than Aviator
- SHA-256 provably fair (vs SHA-512)
Who Aviafly is right for
Pick Aviafly if you genuinely want to alternate between crash and over/under sports-style betting in one client. The dual-mode design is unique among licensed crash games.
Skip Aviafly if you only play Classic crash mode. Aviator at 97% beats Aviafly at 95% on the same gameplay.

Aviafly final pick
Aviafly is the dual-mode crash game. Classic mode at 95% RTP is a worse deal than Aviator at 97% on the same mechanic. Trenball mode is genuinely interesting but most players abandon it after one session. Pick it only if you actually use both modes - otherwise pick a flat-RTP crash with better math.
How to play: first round walkthrough
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.
-
01Open the info panel and confirm the published RTPThe info panel is reachable from the menu icon inside the game. RTP is listed as 95%, the house edge is 5%, and the maximum Trenball payout is x1,000. Aviafly's RTP is flat across the €0.01 to €200 bet range, so the number you see is the number you play at regardless of stake size, unlike Aero Turbo's stake-size sliding RTP.
-
02Pick a stake from €0.01 to €200The bet field accepts any value in the range. Preset chips jump in round increments. The €0.01 floor is the lowest in the crash cohort and makes Aviafly useful as a training cabinet for Trenball timing before a real session. For a first real-money round, something between €0.10 and €1 is a reasonable starting stake while you learn the mode interplay.
-
03Choose your mode: Classic, Trenball, or bothClassic Mode stakes one bet and resolves with manual or auto cash-out. Trenball Mode stakes one to three fixed targets (1.96x, 2x, 10x), each with its own stake and automatic settlement. Dual-Mode Play runs Classic and Trenball together in the same round. If it is your first session, stick to Classic for the first few rounds before layering in Trenball.
-
04Optional: set Auto Cash-Out for Classic modeAuto Cash-Out locks a fixed exit multiplier for the Classic side of the round. Set it to 1.50x for a conservative grind or 5x for a stretch target. Trenball does not need auto cash-out because the targets are pre-committed and self-settling. Avoid using auto cash-out for Martingale-style progressions, as the 5% house edge does not forgive them.
-
05Watch the round play out and settle the outcomesThe biplane lifts off, the multiplier counter climbs, and the coefficient feed shows what other players are doing. If you staked Classic, tap Cash Out the moment you want to lock in the current multiplier. If you staked Trenball, each target auto-settles as the plane passes it, or auto-loses if the plane crashes first. The round ends when the plane leaves the frame, then the next round opens after a short cool-down.
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 provably fair: SHA-256 commit-reveal per round
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. the After 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.
How Aviafly stays honest: SHA-256 commits and the live coefficient feed
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. Aviafly is mechanically honest; whether it is the best value among crash cabinets is a separate question with a clear answer: no, unless you in particular want Trenball.
-
Per-round SHA-256 hash commit and seed revealBefore every round, InOut Games publishes an SHA-256 hash of the server seed. In testing the round ends, the seed is revealed along with the client contribution. Any player who recorded both can recompute the hash, match the commit, and independently derive the crash point. This is the Aviator-tier cryptographic trust model.
-
Transparent coefficient feed inside the gameThe live feed inside Aviafly publishes every round's coefficient, outcome, and round ID. That means a session can be audited empirically across hundreds of rounds: count the 2x hits, check them against the 47.5% theoretical rate at 95% RTP, confirm the distribution shape matches. This is stronger transparency than most crash cabinets ship.
-
Curacao eGaming licensed providerInOut Games holds Curacao eGaming license 8048/JAZ2021-031 at the provider level. Individual operators distributing Aviafly typically hold additional licenses (MGA, UKGC, regional) on top of that. The licensing route is solid, if not the MGA-first tier that high-regulation jurisdictions prefer.
-
No demo-to-real switch behaviourThe free demo hosted on InOut's portal runs the same RNG and distribution as real-money integrations. There is no pattern of players winning in demo and losing in cash mode, which is a recurring complaint against less scrupulous crash titles but not one that has stuck to Aviafly's two-year track record.
-
Two-year public track record since November 2023Aviafly has been live for over two years with no major incident, no regulator suspension, and no documented integrity dispute. That is a shorter record than Aviator's six years but long enough to rule out short-life scam patterns. The sequel Aviafly 2 launched in January 2026 under the same studio without disrupting Aviafly.
The useful criticism of Aviafly is not about rigging. It is about expected value. Aviafly 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.
Aviafly fair verification and Aviafly RTP remain category-standard. Aviafly vs Aviator is the canonical comparison.

Dual-mode play: running Classic and Trenball in one round
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 in particular 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.
Crash probabilities under 95% RTP
At 95% RTP the crash-point distribution follows about 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 about 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 probabilities at the declared RTP produce the distribution above. How to play Aviafly starts with understanding this shape.
Strategies: mode-switching, not just cashout timing
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 in particular, 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.

Two-mode FAQ for Classic-versus-Trenball decisions
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. When after the round ends, we observed 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.

FIVE ESSENTIALS BEFORE PICKING CLASSIC OR TRENBALL
- 01 Aviafly (not Aviafly 2) launched November 2023 by InOut Games with a 95% RTP and a 5% house edge, the highest in our cohort.
- 02 The Trenball mode adds three fixed prediction targets (1.96x, 2x, 10x) that auto-settle without manual cashout, unique in the crash category.
- 03 Dual-Mode Play combines Classic and Trenball in the same round, producing layered outcomes no plain Dual Bet cabinet matches.
- 04 €0.01 minimum bet is the lowest entry point in the cohort, making Aviafly useful for learning twin-mode timing without financial exposure.
- 05 When you want the cheapest house edge, Aviator or Astronaut are better picks. Aviafly is worth the 5% cost only if you in particular want the Trenball layer.
18+ only. Play responsibly. Gambling can be addictive.
