The demo runs in your browser using local storage. It uses virtual coins with no cash value. Wallet facts, game rules, and probabilities are derived strictly from the supplied contract data for Square Range Mines.
Purpose of this Guide
This guide provides an independent, source-bound analysis of the queried game mechanics. It does not invent authors, teams, or business affiliations. The identity of any external entity remains unknown unless explicitly accompanied by a reviewed primary source. This page explains the scope of the demo and how its data is derived.
- No Operator Assumption: References to "the platform" or "the operator" are avoided. The demo belongs to this independent guide.
- Source-Bound Facts: All probabilities, payout structures, and wallet behaviors are based on the supplied mathematical evidence and contract rules.
- Scope Limitation: Terms on this page explain this guide's own scope; they do not invent legal releases or establish an outside company's policies.
Game Mechanics: Square Range Mines
The demo implements Square Range Mines on a 4×4 board with labels 1–16. The core mechanic relies on uniform sampling of complete hazard subsets where the difference between the largest and smallest hazard labels is a perfect square.
| Feature | Rule |
|---|---|
| Board | 4×4 grid, labels 1–16 |
| Hazards | Select 3, 4, or 5. Uniformly sampled from valid subsets (range is a perfect square). |
| Pricing | After each safe reveal, gross value is divided by the exact posterior safe probability; a hazard ends the round with zero return. |
| Collect | Available only after at least one safe reveal. |
| Auto-Bank | Triggers only when no eligible uncertain choice remains. |
For example, with 3 hazards, the support count is 92. If label 3 is printed, the posterior safe probability is approximately 0.837. The initial gross value for a 20-coin stake is 19.4. After one safe reveal, the gross becomes approximately 23.18.
Wallet and Persistence
The demo uses a local virtual wallet stored in browser localStorage. It is not connected to an external bank or account system.
- Initial Balance: 1000 virtual coins.
- Restoration: Manual idle-only restoration. If the balance drops below 10 while idle, you can set it back to exactly 1000. This is not automatic replenishment.
- Fractional Carry: The remainder from settlement persists in local storage across settlement and reload. Zero-return rounds leave it unchanged. Refilling coins does not clear this carry.
- Unfinished Rounds: If you reload during an active round, the captured stake remains deducted. There is no refund or continuation.
Probabilities and Evidence
The expected RTP is 97% across all modes, but this is a mathematical expectation, not a guaranteed session result. Simulation measurements support this but are not the law.
| Hazards | Policy | Expected RTP | Measured RTP (Sample) |
|---|---|---|---|
| 3 | low-1 | 97% | 96.95% |
| 3 | high-2 | 97% | 97.03% |
| 4 | first-4 | 97% | 97.06% |
| 5 | high-2 | 97% | 96.67% |
Different modes have different distributions. The exact policy gross mean remains 0.97 in all tested configurations.
Privacy and Storage
The game stores balance and fractional carry locally. The only observed storage is the virtual-coin balance and fractional payout carry, both stored in localStorage. Clearing cached files may leave local storage intact if not explicitly cleared.
- No Account: There is no login flow; this does not establish the absence of personal-data processing.
- Third Parties: The page template loads Google Fonts stylesheets and font files.
- Anonymity: The absence of account controls does not prove no personal data are processed elsewhere. No anonymity guarantees are made.
Responsible Use and Audience
This guide has an 18+ intended audience. This is a guide-specific designation, not a universal legal age or implemented age gate.
Responsible use is optional. You can set personal time or virtual-coin limits for yourself; the demo does not enforce them. The demo does not clinically train behavior or make losses safe. There are no self-exclusion tools or account-level blocking features in this browser demo. For qualified help, find appropriate local resources.
Frequently asked questions
Is this demo linked to an official casino or app?
No. This is an independent guide's demo. It does not certify or reproduce any outside product. There is no verified app, licence, or official link established by this query.
How does the wallet restoration work?
You can manually restore your balance to exactly 1000 virtual coins only when idle and if the balance is below 10. It is not automatic, and refilling does not clear fractional carry from previous rounds.
What happens if I refresh the page during a round?
The round ends without refund or continuation. Any captured stake remains deducted from your balance. Controls reset to default stake (20) and the first preset.
