The rules, probabilities, and payout structures described below are derived directly from the supplied source contract. No outside platform, licence, or payment service is established by this query or demo.
Game Mechanics and Board Support
The game uses a four-by-four board (16 cells). The board is drawn uniformly from a specific legal support defined by the selected mine count.
- Constraint: Across all columns, there are exactly three nonempty occupied runs in total.
- Uniformity: Draws are uniform over this support, not over all unconstrained boards.
- Mine Count: Choices are limited to the exact nonempty support configurations in the source.
During a round, the chosen mine count and captured stake are locked. Known-certain mines are disabled. Cells with zero conditional safe probability are also disabled.
Payout Formula and 1000x Cap
The gross payout is calculated based on the reduction of the legal board support as safe cells are revealed.
| Component | Description |
|---|---|
| Gross Quote | 0.96 × Captured Stake × Initial Support Count / Current Compatible Support Count |
| Mine Hit | Returns zero gross. |
| Cap | Any safe reveal that would exceed 1000 times the stake is disabled. The current quote is automatically banked when no eligible reveal remains. |
Fractional carry persists across settlement, refill, and reload. The exact expected gross RTP is 0.96 across all modes.
Controls, Modes, and Stopping Rules
Controls: Stake, mine count, and refill are locked while the round is active. Sound remains available. There is no auto queue.
- Manual Bank: Becomes available only after at least one safe reveal.
- Auto-Bank: Occurs when no eligible cell remains (due to cap or exhaustion).
- Stops: A mine ends the round with zero gross. Manual bank or auto-bank ends the round.
Cap guard disables individual above-1000x transitions before a reveal.
Wallet and Restoration
The demo wallet is local and does not involve external accounts or payment flows.
- Initial Balance: 1000 virtual coins.
- Restoration: A manual refill while idle and below 10 sets the integer wallet to exactly 1000. This is a set action, not an addition.
- Fractional Carry: Persists across settlement, refill, and reload.
- Unfinished Round: Reloading an unfinished round ends it without refund or resume.
Mathematical Evidence and RTP
The exact gross RTP is 0.96. Simulation measurements are supporting observations and not the mathematical law.
| Mines | Policy | Exact RTP | Measured RTP | Gross Multiplier |
|---|---|---|---|---|
| 3 | 0 | 0.96 | 96.04% | 1.2038 |
| 3 | 5 | 0.96 | 96.11% | 384 |
| 4 | 5 | 0.96 | 96.38% | 748.8 |
| 5 | 5 | 0.96 | 96.49% | 921.6 |
Expected RTP is not a promised session result. Different modes have different distributions.
Privacy, Storage, and Audience
Storage: Source uses 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.
Audience: 18+ is this guide's intended audience policy, not a claim about local law or an implemented age gate. The demo does not clinically train behaviour or make losses safe.
Frequently asked questions
Does Z93 have a real-money account or payment system?
No. The demo has no account-login flow and no payment flow. Virtual coins have no cash value. This guide is independent and does not certify an outside product.
How is the wallet restored?
A manual refill while idle and below 10 sets the integer wallet to exactly 1000. It does not add coins; it sets the balance. Fractional carry persists.
What happens if I reload during an active round?
An unfinished round ends without refund or resume. The balance settles locally, but the round state is lost.
