How does an Astronaut round run, second by second?

To play the astronaut game online you need five things, and the astronaut game rules fit on one screen: bet, launch, multiplier, Withdraw, or crash. In order:

1. Place the bet.Before the countdown ends, type an amount or tap a quick bet and press Bet. In the astronaut game demo the range is $0.10 to $150 per panel, and the client starts from a default minimum of $0.20 until the server sends its own limits. Everything you choose here is fixed once the rocket lifts off.
2. Wait for the launch.If you change your mind, Cancel returns the bet until the launch. After it, the only button that matters is Withdraw, because the flight is decided by a result that was fixed before takeoff.
3. Watch the multiplier.It starts at 1.00x and rises as one continuous number, not in steps. A value such as 14.05x, which we read in the demo history on 12 October 2026, is one round, not a published figure.
4. Press Withdraw.It pays that panel’s bet × the multiplier at the moment you press: Rs 1,000 withdrawn at 2.50x returns Rs 2,500, a gain of Rs 1,500. Each panel has its own button.
5. Or the rocket crashes.If the crash comes first, the panel loses its bet. The crash point was fixed before takeoff, and a new countdown starts straight away.

What does each control on the Astronaut screen do?

The client v2 packs the game into one scene. Labels follow the English client as read in 100HP’s demo on 12 October 2026; a casino’s wrapper can word them differently.

How do the two bet panels work, and why use both?

Astronaut gives you two bet panels side by side, so you can place two independent bets in the same round, each with its own amount, Cancel or Withdraw button, Autobet and Autowithdrawal. The usual use is a safe bet and a risky bet: panel one targets a low multiplier to get the stake back, panel two stays in the flight for a bigger one. What it means for you: two panels do not change the RTP, they split one decision into two (round numbers below, an illustration, not a recommendation).

What are Autobet and Autowithdrawal, and what mistakes do they cause?

Autobet repeats your bet in every following round with the same amount, and Autowithdrawal is a multiplier target at which the game presses Withdraw for you; the client’s default is 2.00x. By default the field accepts values from 1 to 100x, and the server, meaning the operator, can override that range, so the 100x is the size of the input box, not a ceiling for the flight. What it means for you: an automatic exit fires on a number you chose before the round, so it is only as good as that number. At 2.00x every round that crashes earlier still loses the bet.

Typical slips: leaving Autobet on, and forgetting that a target set on panel 1 does not apply to panel 2.

When should you press Withdraw, and what does waiting cost?

There is no best moment, and the arithmetic shows why. This is not 100HP data: if the declared RTP of 98% holds for whatever target you choose, a bet withdrawn at a multiplier m reaches it in about 98 ÷ m rounds out of 100 and crashes first in the rest.

What it means for you: waiting for a bigger multiplier does not raise the return, it only moves wins from frequent and small to rare and large. 100HP does not publish the distribution of crash points, and a lower casino RTP lowers every row. Decide the exit before the countdown ends.

How do Hash and Salt show that a round was not rigged?

Astronaut shows a Hash before the flight and reveals a Salt after it. Both appear in Round details with the Round ID and the final multiplier, and the Fairness check window compares the pair and reports verification success or failed; to check a finished round, open its Round details, copy the Hash and the Salt and read the verdict. This is what provably fair means in the client: the result exists before the rocket takes off, and afterwards you can test that it was not changed. 100HP does not publish the exact algorithm, so the “server seed + client seed + nonce” description on affiliate sites is not an official statement.

What it means for you: the check proves a round was not altered after the fact, not that you will win, and a fair round can still crash early. It also removes the idea behind predictors, since a result that is only fingerprinted before the flight cannot be read from outside; see why Astronaut predictors cannot work and Hash, Salt and the Fairness check.

How should you read the volatility and the Last rounds strip?

Why does 100HP call the volatility Very High?

Volatility measures how far results swing around the average. 100HP rates Astronaut as Very High on its game card, while affiliate pages write High. In practice you set the risk yourself: leaving at 1.2x to 1.5x gives frequent small wins, and waiting for 10x or more means most rounds crash before you leave.

Can the Last rounds strip predict the next crash?

No. The Last rounds strip shows earlier results as chips, blue, green and yellow for rising multipliers and red for a crash, and the chips are a record, not a pattern. 100HP publishes nothing that links one round to the next, and each round’s Hash is shown before the flight, so a run of reds is information about the past only.

Which client version are you looking at: v1, v2, Second Chance or Rivals?

The official launch of Astronaut opens a page whose address contains astronaut2: that is the second generation of the game client, with the dual bet panels, while the older client v1 answers at the address without the number. Neither is a sequel; Astronaut Second Chance and Astronaut Rivals are separate titles with unpublished rules.
