Identity & APK Status
No APK, package signature, publisher or app-store listing is verified here. A similarly named domain or search snippet does not establish authenticity. Before relying on a package, compare its exact identifier, publisher and signature against an identifiable primary source.
Browser Demo vs. APK
The browser demo needs no APK installation and has no account or payment flow. Its rules describe this guide’s own implementation; they cannot be attributed to an unverified outside package.
Wallet & Persistence Rules
The demo’s wallet follows strict local persistence rules defined by the contract. These rules apply to the browser demo and are independent of any APK’s wallet behavior.
| Feature | Rule |
|---|---|
| Initial Balance | 1000 virtual coins |
| Refill Condition | Manual, idle-only, when balance < 10 |
| Refill Result | Balance set exactly to 1000 |
| Fractional Carry | Persists across settlement, refill, and reload |
| Unfinished Round | Ends on reload; no refund or resume |
Game Mechanics: Column Lex Zigzag
The board has 4×4 cells and exactly 3, 4 or 5 mines. Read each column from top to bottom as a four-bit integer: mine = 1, safe = 0, weights 8, 4, 2, 1. From left to right, the column values must satisfy c0 ≤ c1 ≥ c2 ≤ c3; equality is allowed. Draws are uniform among boards satisfying both this rule and the selected mine count. Initial support sizes are respectively 150, 464 and 1053. Revealing a safe cell filters the compatible support.
After a safe reveal, gross quote = 0.96 × captured stake × initial support / current compatible support. The stake is deducted when the round starts. A mine returns zero gross. Manual banking is available after at least one safe reveal. Certain mines and cells whose safe quote would exceed 1000× stake are disabled. All safe cells revealed or no eligible cell remaining automatically banks the current quote. A certain-safe cell can remain eligible. With five mines, singleton support would quote 1010.88×, so that above-cap transition is disabled.
Mathematical Evidence & RTP
The exact expected gross return for the checked bounded policies is 0.96 of stake. Saved simulation observations are samples, not promised session results. Three- and four-mine singleton quotes are 144× and 445.44×. With five mines, singleton quote 1010.88× exceeds the cap and is disabled; a compatible support of two would quote 505.44×. The 252.72× example in the saved evidence is a particular saved path with four compatible boards, not the maximum.
Privacy & Storage
The demo stores balance and fractional carry in browser localStorage. It has no account or payment form; this does not establish anonymity or exclude other processing. Pages request Google Fonts and Statinside counter 44. Those requests may convey the IP address and browser request information to those services. Server retention and other processing are not established here. Clearing this site’s localStorage or site data removes balance and carry; clearing only cached files may leave them intact.
Frequently asked questions
Is the AQ9 Android APK verified?
No. The APK identity is unverified. No official package signature or verified app store listing is established by this query. A similarly named domain or search position is not evidence of an official app.
Do I need to install the APK to play?
No. This browser demo requires no installation. It runs independently in your browser and does not rely on the APK. The demo uses local storage for balance and does not sync with the APK.
How does the wallet refill work in the demo?
The refill is manual, idle-only, and available only when the balance is below 10. It sets the balance to exactly 1000. Fractional carry persists across refills and reloads. Unfinished rounds end without refund on reload.
