Because this is a browser demo, there is no account-login flow, no cash withdrawal system, and no external payment gateway connected to this specific instance. The absence of these features in the demo does not prove that a separate commercial platform does not exist, but it does mean no verified app has been confirmed for this guide.
Browser Demo vs. Verified App
The current interface is a direct browser execution. It does not require you to download an executable file or install a native app from an app store. Consequently, there is no verified app package identity associated with this demo session.
A search snippet or a similarly named domain does not constitute evidence of an official company, account address, or verified service. This page describes the limits of the browser demo and the uncertainty regarding any external mobile application.
Wallet and Balance Mechanics
The demo uses a virtual wallet to track your progress. The initial balance is set to 1000 virtual coins.
| Feature | Rule |
|---|---|
| Restoration | Manual refill while idle, when balance is below 10, sets the balance to exactly 1000. |
| Fractional Carry | Persists across settlement, refill, and reload. |
| Unfinished Round | Ends without refund or resume upon reload. |
| Cash Value | Virtual coins have no cash value and cannot be withdrawn. |
Game Mechanics: Row Boundary Equality
The demo runs the Row Boundary Equality game. A four-by-four board is drawn uniformly from all boards with the selected mine count satisfying the rule that every row has equal first and last occupancy bits.
- Gross Quote: 0.96 × captured stake × initial support / current compatible support.
- Cap: Cells whose safe quote would exceed 1000 times stake are disabled.
- Auto-Bank: When no eligible cell remains, the current quote is banked automatically.
Privacy and Storage
This demo uses browser localStorage for settled demo balance and fractional carry. This does not establish anonymity or exclude other processing.
- Third Parties: The page declares Google Fonts requests and the production builder includes Statinside visitor counter 44. These observations do not establish anonymity or absence of other processing.
- Data: The absence of account or payment controls in the demo does not prove that no personal data are processed.
Responsible Gaming & Audience
18+ is this guide's own intended audience policy, not a claim about local law or an implemented age gate.
Responsible use involves optional pauses, setting a personal time or virtual-coin limit, and finding appropriate local qualified help. The demo does not clinically train behavior or make losses safe.
Mathematical Evidence
Simulation measurements are supporting sample observations, not the mathematical payout law. The exact gross RTP is 0.96.

Policy 0–5 labels identify saved test reveal paths, not additional controls in the interface. The selected mine counts are 3, 4 and 5. Table values are display-rounded observations, while exact expected gross RTP is 0.96.
Frequently asked questions
Do I need to download an app to play?
No. This browser demo runs directly in your web browser without any download or installation process.
Is KM4 a verified app?
No. While the name KM4 is queried, no specific app package or verified mobile application has been confirmed for this independent guide.
How is my balance restored?
A manual refill while idle and below 10 sets the integer wallet to exactly 1000. Fractional carry persists across settlement and reload.
