How to play

A rocket sits on the launch pad. Once it lifts off, a multiplier starts at 1.00× and keeps rising until, at some unknown point, the rocket blows up. If you cash out while it’s still in the air, your bet is paid back times the multiplier showing. If it crashes first, the bet is gone.

Before launch. Pick a chip (100, 500, 1,000 or 5,000) and tap the bet spot to stack it. Bets run from 100 to 10,000 credits in steps of 100. Clear empties the spot and Rebet brings back your last stake. Under Auto cash out you can choose Off, 1.50×, 2.00×, 5.00× or 10.00×; the game remembers your choice for next time.

In flight. Press Launch. The single big button now reads “Cash out” with the amount you’d collect right now, and that number ticks up with the multiplier. Tap it, or press Space or Enter, and you lock in the payout. With an auto target set, the game cashes out for you the instant the multiplier reaches it, and you’re still free to bail out earlier by hand. The earliest possible cash-out is 1.01×.

After the flight. A message tells you where you cashed out and where the rocket crashed anyway, or where it went down with your bet on board. A strip along the top lists recent crash points, up to the last twenty.

You start with 10,000 credits. If you drop below the 100 minimum, a button gives you another 10,000 free.

How fast the multiplier climbs

The curve is exponential: the multiplier equals e raised to 0.06 times the seconds elapsed. In practice that means the early part feels slow and the late part feels frantic.

MultiplierTime after launch
1.50×about 6.8 s
2.00×about 11.6 s
5.00×about 26.8 s
10.00×about 38.4 s
100×about 77 s
1,000× (the ceiling)about 115 s

Every doubling takes the same 11.6 seconds, so going from 50× to 100× takes as long as going from 1× to 2×, yet adds fifty times more to the payout.

Where the rocket crashes

The crash point is fixed the moment you press Launch and is hidden until the flight ends. It’s generated so that the chance of the rocket getting past any multiplier m is 0.97 ÷ m, with a hard floor at 1.00× and a hard cap at 1,000×.

TargetChance of reaching itAverage return per 100 bet
1.50×64.7%97
2.00×48.5%97
5.00×19.4%97
10.00×9.7%97
100×0.97%97

The last column is the whole point. Chance times payout always comes to 0.97, so every cash-out target returns 97% of what you stake over the long run. Because bets come in hundreds and multipliers in hundredths, the payout is always a whole number of credits and nothing is lost to rounding.

There’s also a built-in instant loss. About 3.96% of rockets crash at 1.00×, before even the earliest cash-out is possible. On those rounds every player loses, whatever target they chose.

Strategy

No target beats another on average, so pick one for the kind of session you want rather than for the odds.

  • Low targets, like 1.50×, win about two rounds in three. The balance moves in small steps and long losing runs are rare.
  • High targets, like 10×, lose nine rounds in ten. You need a deep balance relative to the bet to wait for the hit.
  • Use auto cash-out to avoid hesitation. Watching the number climb invites “just a bit more”. An auto target removes that.
  • The history strip is entertainment, not information. Each crash point is independent. A run of low crashes doesn’t make a high one due.

Multiplier Rocket is a sister game with its own rules for the climb. Balloon Pump puts the same “stop before it pops” decision into pump-by-pump steps.

Frequently asked questions

When is the crash point decided?

At the moment you press Launch. It's hidden from the screen until the flight ends, and nothing you do during the flight changes it.

Which cash-out multiplier is best?

None. The chance of reaching m is 0.97 ÷ m, so every target returns 97% of the stake on average. Lower targets just win more often for smaller amounts.

Can the rocket crash immediately?

Yes. About 3.96% of flights end at 1.00×, before any cash-out is possible.

What is the highest multiplier?

1,000×. No flight goes past it, and reaching it takes almost two minutes.

What happens if I close the game during a flight?

The round is saved with its crash point. When you come back, the flight continues and crashes at the same point.

Are the credits real money?

No. Credits are virtual and exist only in this game. They can't be bought, cashed out or exchanged for prizes.
