For readers in the Philippines, this is a free-to-play experience. You can test the mechanics without spending your own money, but always remember to check the official site for real-money details.
Game Rules and Board Support
The board is a four-by-four grid. A mine count is selected from exact non-empty support configurations. Boards are drawn uniformly from this constrained support, not from all possible boards. A board is legal only if it has exactly three non-empty occupied runs in total across columns.
After any safe reveal, the board support is filtered. Cells with zero conditional safe probability are disabled. Cells whose safe quote would exceed 1000 times the stake are also disabled.
What Filipino Players Should Check Before Playing
If you are playing from the Philippines, keep in mind that this is an independent guide. The game itself is free, but if you decide to play for real money, you need to verify a few local details. First, check if the operator supports the Philippine peso (PHP) as the primary currency. Second, look for local payment methods like GCash or Maya, which are commonly used here, rather than just international credit cards.
You should also check the licensing status. The main regulator in the Philippines is PAGCOR. See if Z93 holds a valid license from them or another recognized body. For your safety, always check the terms and conditions on the operator's site to confirm these details before depositing.
- Verify if GCash or Maya are available for deposits.
- Check for PAGCOR or other valid gaming licenses.
- Confirm that the PHP currency option is active.
Scoring and Payout Formula
The gross quote is calculated as: 0.96 × captured stake × initial support / current compatible support. Captured stake and mine count are locked for the round. If a mine is revealed, the gross return is zero. Fractional carry persists across settlement, refill, and reload.
Controls, Modes, and Stopping
- Controls: Stake, mine count, and refill are locked while active. Manual bank is available only after at least one safe reveal. No auto queue.
- Stopping: A mine ends the round. Manual bank or automatic banking (when no eligible reveal remains) ends the round.
- Cap: A 1000× stake cap disables transitions. No eligible reveal automatically banks the quote; manual action is required.
Mathematical Evidence and RTP
The exact gross RTP is 0.96 across all modes. Simulation measurements are supporting observations, not the exact law. Below are exact values for specific safe paths:
| Mines | Safe Path | Remaining Support | Gross Multiplier |
|---|---|---|---|
| 3 | [0] | 319 | 1.2037617554858935 |
| 3 | [0,1,2] | 192 | 2 |
| 4 | [0,3,6,9,12,15,2,5,8,11,13,1] | 1 | 748.8 |
| 5 | [0,3,6,9,12,15,2,5,8,13,4] | 1 | 921.6 |
Wallet and Persistence
The demo starts with a balance of 1000. A manual idle-only refill sets the balance to exactly 1000 if it is below 10; it does not add coins or replenish automatically. Settled balance persists locally, including zero. Unfinished rounds end without refund or resume on reload.
Privacy and Storage Facts
Browser localStorage is used for settled demo balance and fractional carry. This does not establish anonymity. The template declares a Google Fonts stylesheet, but actual request capture is pending. There is no demo account or payment flow.
Frequently asked questions
How is the board drawn?
Boards are drawn uniformly from the exact legal board support defined by the selected mine count and the rule that there are exactly three non-empty occupied runs across all columns.
What is the exact payout formula?
Gross quote = 0.96 × captured stake × initial support / current compatible support. Mine returns zero.
Can I auto-bank?
No. Manual bank is available only after a safe reveal. Automatic banking occurs only when no eligible reveal remains.
What happens if I hit a mine?
The round ends immediately with a gross return of zero.
How does the 1000x cap work?
Cells whose safe quote would exceed 1000 times the stake are disabled. The cap guard disables transitions before a reveal.
What is the exact RTP?
The exact gross RTP is 0.96 across all modes. Measured RTP varies slightly in simulations (e.g., 96.04357617554858 for mines=3, policy=0).
How does the wallet refill work?
Manual idle-only refill sets the integer wallet to exactly 1000 if the balance is below 10. It preserves fractional carry.
Does the balance persist if I reload?
Settled balance persists locally, including zero. Unfinished rounds end without refund or resume on reload.
Is there a demo account?
No. There is no demo account flow or payment flow. The demo uses virtual coins with no cash value.
What data is stored?
Browser localStorage is used for settled demo balance and fractional carry. A Google Fonts stylesheet is declared, but actual request capture is pending.
Is this a real casino?
No. This is an independent guide's demo. It does not certify or reproduce any outside product. There is no operator, licence, or KYC.
Who is the audience?
The intended audience is 18+, which is this guide's policy, not a universal legal age or an implemented age gate.
Is this game available for free in the Philippines?
Yes, the demo version uses virtual coins and is free to play. You do not need to deposit real money to try it out.
How do I know if Z93 is regulated in the Philippines?
Check the official Z93 website for licensing information. Look specifically for approval from PAGCOR, the Philippine Amusement and Gaming Corporation, or other relevant local authorities.
