What Rocket X is
Rocket X is an online game in the crash-game genre, developed by the studio 1win Gaming and released in 2021. 1win Gaming is the in-house developer of the operator of the same name, 1win, and Rocket X is an exclusive game of that platform: you can only access it through 1win, unlike Aviator or JetX, which are licensed to many casinos.
Visually, the game is built around an animation of a launching rocket that climbs up the screen. The higher the rocket flies, the bigger the player's bet multiplier. At a random moment of the flight a "crash" occurs: the rocket explodes, and everyone who didn't manage to collect their winnings loses their bet. The player's goal is to press the Cash Out button before the crash.
The crash-game genre was born around 2014 in the crypto industry (the first commercially notable game was Bustabit), went mainstream in 2019 with Aviator by Spribe, and over the following few years became one of the largest segments of the mobile online casino. Rocket X is one of the significant products of that wave, especially popular in Eastern Europe and the CIS. For more on the genre's timeline, see the "History of the genre" page.
The goal of the game in one paragraph
Before the round starts, the player places an amount. After the start, a rocket appears on the screen, and next to it a multiplier begins to grow — 1.00× → 1.20× → 1.50× → and so on. It grows smoothly, without visible jumps. At an arbitrary moment (from a fraction of a second to tens of seconds) the rocket crashes, and the multiplier is locked at its last value. If the player managed to press Cash Out before the crash, they receive their bet × the current multiplier. If they didn't, they lose the entire amount staked.
The player decides for themselves when to cash out. This creates an illusion of control on which the entire psychology of crash games is built. For more on this trap, see the article "Strategy myths".
The interface: what the player sees on screen
Despite the simplicity of the mechanics, the Rocket X interface contains about a dozen elements. Below are the main ones, in order of how often they're used.
| Element | What it does | Where it is |
|---|---|---|
| Bet field | Entry of the amount for the upcoming bet. Often has 2×, +10, +100 buttons for quick changes | Left or bottom panel |
| "Bet" button | Confirms entry into the next round. Active only during the betting phase | Below the bet field |
| Cash Out button | Collects winnings at the current multiplier. Active only while the rocket is in flight | Same position as "Bet" — switches by phase |
| Auto-cashout field | The multiplier at which the system automatically presses Cash Out. Off by default | Next to the Cash Out button |
| Round history | A feed of the last 20–50 multipliers at which the crash occurred | At the top or in a side panel |
| Player chat | A shared chat for all players in this round. Can be turned off in settings | Side panel |
| Live-wins feed | Which amounts and at which multipliers other players are cashing out right now | Above the game screen |
| Provably Fair | A section for verifying a round's fairness via the server-seed hash | Game settings menu |
Since Rocket X is an exclusive 1win game, the interface is the same everywhere: there are no variations for different operators. This makes it easier for players to learn, but it also makes Rocket X unavailable on other platforms — unlike Aviator, which is licensed to hundreds of casinos.
The three phases of a round
One full Rocket X cycle takes roughly 15–20 seconds and is divided into three clearly distinct phases. Understanding their structure helps you appreciate how quickly decisions are made.
Phase 1 — Betting (5–7 seconds)
After the previous round ends, the system opens a window for new bets. Players see a countdown timer. During this phase you can:
- Place one bet or two at once
- Set up auto-cashout (the cash-out multiplier)
- Enable auto-bet for the next N rounds in a row
Once the timer runs out, bets are locked automatically — you can no longer change or cancel them.
Phase 2 — Rocket flight (from 1 to 30+ seconds)
The rocket launches, and the multiplier begins to grow from 1.00×. The flight duration is unpredictable: in most rounds the crash happens at a multiplier below 2.00× (that's about 51% of rounds), but occasionally the rocket reaches 50×, 100×, or even higher. Players see:
- The current multiplier value, large, in the center of the screen
- The animated rocket flight
- The Cash Out button, active at any moment
- The potential winnings amount at the current multiplier
Phase 3 — Crash and pause (2–3 seconds)
The rocket explodes. The final multiplier is locked and goes into the round history. Players who managed to press Cash Out receive their winnings to their balance instantly. The rest lose their bet. Then a short pause, and the cycle begins again.
Two bets at once — why
Rocket X lets you place two independent bets in a single round. This isn't "doubling your bet," but two entirely separate bets with their own amounts, their own auto-cashout settings, and their own Cash Out buttons. On screen they're shown as Bet 1 and Bet 2.
Why does the casino offer such an option? It's usually used as pseudo-insurance: you place the first bet with a low auto-cashout (say, 1.30×) — it almost always triggers, giving a small profit. And the second one with a high auto-cashout (say, 10×) in the hope of catching a "fat" round.
Mathematically, two bets with different cash-out targets are equivalent to one bet of double the size with an averaged target. A 96–97% RTP applies to every unit of currency staked, regardless of how it's split across bets. With two bets you simply lose twice as fast.
Automation — auto-bet and auto-cashout
In Rocket X you can automate both key operations — placing the bet and cashing out. Many players set up automation and leave the game to run on its own.
Auto-cashout
The most popular automation: you set a specific multiplier (say, 1.50× or 2.00×), and when the round reaches that value, the system instantly presses Cash Out for you. This solves the slow-reaction problem — no human can react to the multiplier faster than 150–200 ms, whereas automation triggers instantly.
Auto-bet
You can set how many rounds in a row the game should place bets automatically — usually from 10 to 100. The options include conditions for stopping: "stop if the balance falls below X," "stop if winnings exceed Y," "stop on a single loss." Combining auto-bet and auto-cashout turns the game into a fully passive process.
Auto-mode removes the emotional barrier. With each manual bet the player feels the decision and its cost; on automation, they simply watch a vanishing balance. Most heavy losses in crash games happen precisely during long auto-sessions, when the player "got distracted for a minute."
Rocket X vs Aviator vs Lucky Jet — what's the difference
The three most popular crash games in the Russian-speaking segment are Aviator (Spribe), Lucky Jet (Gaming Corps), and Rocket X (1win Gaming). In terms of mathematics they're close — the differences are in the visuals, the UX, and a small spread in RTP.
| Parameter | Aviator | Lucky Jet | Rocket X |
|---|---|---|---|
| Developer | Spribe | Gaming Corps | 1win Gaming |
| Release date | 2019 | 2021 | 2021 |
| Visual metaphor | Airplane | Pilot with a jetpack | Rocket |
| Stated RTP | ~97% | ~97% | ~96% |
| Provably Fair | Yes | Yes | Yes |
| Two bets | Yes | Yes | Yes |
| Chat | Yes | Yes | Yes |
Choosing between these three games is a choice of visual wrapper, not mathematics. In terms of chances of winning and average expectation, all three are equivalent. If forums tell you "Rocket X has a higher RTP than Aviator," that's either a mistake or the marketing of a specific operator.
