All three tools use one model taken from the game's stated 97% return: the chance a round
reaches a multiplier is 97 divided by that multiplier.

Worked examples in ZAR
This calculator opens at a 10 rand bet. It prices the bet and nothing else: the cost of a voucher or a bank charge, where one applies, is not part of these figures.
A R5 bet cashed out at 1.5x returns R7.50, a profit of R2.50. A round gets that far 65% of the time.
A R10 bet cashed out at 2x returns R20, a profit of R10. A round gets that far 48% of the time.
A R50 bet cashed out at 5x returns R250, a profit of R200. A round gets that far 19% of the time.
A R50 bet cashed out at 10x returns R500, a profit of R450. A round gets that far 9.7% of the time.
Each example has the same expected return of 97%. On a R10 bet that is an average cost of R0.3 per round, whichever line you pick.
The numbers
Aviator odds: the chance of reaching each multiplier
With a 97% return, the chance that a round reaches a multiplier is 97 divided by that multiplier.
A 2.00x cash-out is reached in 48.5% of rounds, not half of them. That missing 1.5% is the house
edge, and it is in every row of the table below.

Read the last column twice. Whatever multiplier you pick, 100 rounds at a R10 stake are
expected to cost R30 . A low target wins often and pays little. A high target wins rarely
and pays a lot. The long-run cost is the same 3% of everything you stake, which is why no choice of
cash-out point counts as a winning system.
What changes with the target is the ride. At 1.20x you win about four rounds in five and losses
come in ones and twos. At 10x you win about one round in ten and can easily sit through twenty
losing rounds first. Pick the ride you can afford, not the one that sounds biggest.
What a session costs in ZAR
The 3% edge applies to everything you stake, so the expected cost of a session grows with the number of rounds, not with the multiplier you aim for. The table uses a R10 stake.

FAQ
Aviator calculator: questions and answers
How much does a R10 bet return at 2x?
R20, which is a profit of R10. A round reaches 2.00x 48.5% of the time.
How much can a R50 bet win at 10x?
R500 back, a profit of R450. A round reaches 10x 9.7% of the time, which is about 1 round in 10.
Does the calculator use real rand?
No. The calculator and the practice round show demo credits in rand so the numbers look familiar. Nothing here can be deposited, won or withdrawn.
How we check
Operator details are the figures each site publishes, and a field we do not hold is marked
“Not confirmed”. Regulator, law and age limits come from the authority's own material.
The odds, the calculator and the simulator all come from the provider's stated 97% return.
Rounds this fast make it easy to bet more than you planned. Set a deposit limit before your first real
round, never chase a loss, and stop when it stops being fun.
