Game Board and Support
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.
Payout and Settlement
After a safe reveal, the gross quote is calculated as 0.96 × captured stake × initial support count / current compatible support count. If a mine is revealed, the return is zero. Cells with zero conditional safe probability are disabled. Cells whose safe quote would exceed 1000 times the stake are also disabled.
Stopping Rules and Caps
A manual bank becomes available only after at least one safe reveal. The round ends if a mine is hit, the player banks manually, all safe cells are revealed, or no eligible cell remains. When no eligible cell remains, the current quote is banked automatically. The 1000× stake cap is enforced by disabling individual transitions that would exceed it.
Wallet and Refill
The demo wallet starts with 1000 virtual coins. A manual refill while idle and below 10 sets the balance to exactly 1000, preserving any fractional carry. Fractional carry persists across settlement, refill, and reload. Unfinished rounds end without refund or resume on reload.
Mathematical Evidence
The exact gross RTP is 0.96 across all modes. Below are measured estimates from simulations:
| Mines | Policy | Measured RTP | Gross Multiplier |
|---|---|---|---|
| 3 | 0 | 96.03% | 1.007 |
| 3 | 1 | 96.05% | 1.636 |
| 3 | 4 | 95.63% | 144 |
| 4 | 0 | 96.01% | 1.043 |
| 5 | 5 | 96.51% | 252.72 |
Privacy and 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 this an official AQ9 casino?
No. This is an independent guide demo. The query does not establish an official operator, licence, or verified app.
How does the wallet refill work?
Manual refill while idle and below 10 sets the balance to exactly 1000. It preserves fractional carry. It does not add coins; it sets the balance.
What happens if I reload during an unfinished round?
The unfinished round ends without refund or resume. Only settled balances persist locally.
