MMY Aviator Pro: the published rules
Aviator Pro is a round-based multiplier game, as the developer describes it on mmy.com.
How a round works
A round starts and a multiplier scale begins to climb. It can stop at any moment. You take your return by cashing out while it is still climbing. If the round ends before you cash out, that round pays nothing.
What you decide
The only decision inside a round is when to cash out. There is no board to read and no hand to play. The developer's description calls it simple for that reason, and notes the format came out of video games before it showed up in casinos.
What is not published
The developer does not publish the ceiling, the round length, or how the stopping point is chosen. Those live in the app, inside an encrypted script, so this page does not guess them.
Where this comes from
The description on this page follows the text on mmy.com, the developer's site. Rule details that the developer does not publish are marked as not published, rather than filled in from other sites. Several MMY download sites state version numbers and file sizes that do not match the measured file; their game rules are not a safer source.
The game runs inside the MMY app, version 2.2.5, and there is no standalone download for it. Get the MMY APK

Playing it on a phone
The game runs inside the one MMY package, so the constraints are the package's. It needs Android 7.0 or newer and an arm64 handset, it installs as 19.98 MB, and the first launch downloads the game's assets over the network. A phone on a metered connection will spend that data once per fresh install. Later opens reuse what was fetched, until you clear the app's data.
Nothing on this page quotes a stake, a payout or a house edge. Where the developer publishes those they belong in the description above; where the developer does not, the table inside the app is the only place they appear, and they can change without this page knowing.
