- No Operator Identity: The queried name does not establish a specific company, licence, or verified app. This guide does not assume an outside platform exists.
- Original Demo: The virtual-coin demo uses a four-by-four board with a specific support constraint: exactly three nonempty occupied runs in total across all columns.
- Wallet Rules: Balance restoration is manual and sets the wallet to exactly 1000. Fractional carry persists across settlement and reload.
Game Mechanics and Support
The game uses a four-by-four board. A board is drawn uniformly from all boards with the selected mine count that satisfy the public support rule: Across all columns there are exactly three nonempty occupied runs in total.
This constraint defines an exact finite board support. Draws are uniform over that support, not over all unconstrained boards. Each safe reveal filters the support.
| Feature | Rule |
|---|---|
| Board Size | 4x4 |
| Support Constraint | Exactly 3 nonempty occupied runs in total across all columns |
| Draw Method | Uniform over legal support |
| Stake Lock | Captured stake and mine count do not change during round |
Payouts and Scoring
The score function is defined by the remaining compatible support size. After any safe path, the gross cashout is calculated as:
Gross Quote = (0.96 × captured stake × initial support size) / current compatible support size
Mine returns zero. Cells with zero conditional safe probability are disabled. Cells whose safe quote would exceed 1000 times stake are disabled.
| Mines | Safe Path | Remaining Support | Gross Multiplier |
|---|---|---|---|
| 3 | [0] | 319 | 1.2037617554858935 |
| 3 | [0, 1, 2] | 192 | 2 |
| 3 | [15, 14] | 250 | 1.536 |
| 3 | [0, 3, 6, 9, 12, 15, 2, 5, 8, 11, 14, 1, 4] | 1 | 384 |
| 5 | [0, 3, 6, 9, 12, 15, 2, 5, 8, 13, 4] | 1 | 921.6 |
When no eligible cell remains, the current quote is banked automatically.
Controls and Modes
The demo supports specific modes based on the exact nonempty support configurations in the source.
- Manual Bank: Becomes available only after at least one safe reveal.
- No Auto Queue: Manual idle-only refill is the only replenishment method.
- Stake Lock: Captured stake and mine count are locked throughout the round.
- Sound: Remains available during play.
A manual refill while idle below 10 sets the integer wallet to 1000 and preserves fractional carry.
Wallet and Persistence
The wallet behavior is strictly defined by the contract:
- Initial Balance: 1000.
- Restoration: Manual set when idle and balance below 10. Sets balance to exactly 1000.
- Fractional Carry: Persists across settlement, refill, and reload.
- Settled Balance: Persists locally, including zero.
- Unfinished Round: Ends without refund or resume on reload.
Busy controls lock stake, mine count, and refill while the round is active. Eligible reveal cells and bank remain available; sound remains available.
Mathematical Evidence
The exact gross RTP is 0.96 across all modes. Simulation measurements are supporting sample observations, not the mathematical payout law.
| Mines | Policy | Exact Gross RTP | Measured RTP | Surviving Boards | Gross Multiplier |
|---|---|---|---|---|---|
| 3 | 0 | 0.96 | 96.04357617554858 | 319 | 1.2037617554858935 |
| 3 | 1 | 0.96 | 95.9742 | 192 | 2 |
| 3 | 5 | 0.96 | 96.1128 | 1 | 384 |
| 4 | 5 | 0.96 | 96.37992 | 1 | 748.8 |
| 5 | 5 | 0.96 | 96.49388307692307 | 1 | 921.6 |
Privacy and Technical Details
The demo stores its settled balance and fractional carry in browser localStorage for settled demo balance and fractional carry. This does not establish anonymity or exclude other processing.
- Third Parties: The template declares a Google Fonts stylesheet. Actual browser request capture is pending; this is not a claim that other requests or processing are absent.
- Account Flow: None. No login flow exists in this demo.
- Payment Flow: None. Virtual coins have no cash value.
Clearing cached files may leave local storage. The absence of account controls does not prove that no personal data are processed.
Frequently asked questions
Is Z93 an official casino operator?
This guide does not verify any external Z93 operator. The queried name alone does not establish a company, licence, or verified app. This demo belongs to this independent guide and does not certify or reproduce any outside product.
How does the wallet refill work?
Refill is manual and idle-only. When the balance is below 10 and the user is idle, a refill sets the integer wallet to exactly 1000 and preserves fractional carry. There is no automatic replenishment or refill during an active round.
What happens if I reload the page during a round?
An unfinished round ends without refund or resume. The settled balance persists locally, but the current round's progress is lost.
