Unlike standard versions, this demo uses a uniform draw from a filtered support set. The payout is based on the shrinking support size rather than simple cell counts. This page is an independent resource, not the official operator site.
Game Rules and Support Constraint
A four-by-four board is drawn uniformly from all boards that satisfy a specific public support rule: among the three neighbouring pairs along the anti-diagonal, exactly one pair has equal occupancy bits. This constraint defines an exact finite board support. Draws are uniform over that support, not over all unconstrained boards.
The board size is four-by-four. Mine count choices are only the exact nonempty support configurations in the source. Safe reveals condition this legal-board support; after any safe path, the gross cashout is calculated as 96 percent of captured stake times initial support size divided by current compatible support size.
Known-certain mines are disabled. Any safe reveal that would exceed the public 1000-times-stake cap is disabled. When no eligible reveal remains, the current quote is automatically banked.
What Philippine Players Should Check
Since this is a free demo, you are playing with virtual currency. However, if you decide to play for real money later, you must verify the following details directly with the in22 operator, as these can change without notice.
- Currency: Confirm if the real money version supports the Philippine Peso (PHP) for your balance.
- Payment Methods: Check if local wallets like GCash and Maya are accepted for deposits and withdrawals.
- Regulation: Verify if in22 is licensed by PAGCOR (Philippine Amusement and Gaming Corporation) or holds another valid license for Filipino players.
- Safety: Always check the official website or app for the latest terms regarding data privacy and responsible gambling limits.
Payout Math and Score Function
The score function is defined by the uniform legal-board support at the selected mine count. After safe reveals, the gross quote equals 0.96 × captured stake × initial support count divided by current compatible support count. A mine returns zero.
Cells with zero conditional safe probability are disabled. Cells whose safe quote would exceed 1000 times stake are disabled. When no eligible cell remains, the current quote is banked automatically.
| Scenario | Mines | Safe Path | Remaining Support | Gross Multiplier |
|---|---|---|---|---|
| Example 1 | 3 | [0] | 134 | 1.1319402985074627 |
| Example 2 | 3 | [0, 1, 2] | 92 | 1.6486956521739131 |
Fractional carry persists across settlement, refill, and reload. The exact expected value is distinct from measured estimates.
Controls and Modes
- Board: Four-by-four grid.
- Mine Count: Limited to exact nonempty support configurations in the source.
- Stake: Locked throughout the round along with the mine count.
- Banking: Manual bank becomes available only after at least one safe reveal. No auto queue is used.
- Sound: Remains available during the round.
- Refill: Manual idle-only refill. No refill occurs during an active round.
Wallet, Balance, and Persistence
The wallet starts with an initial balance of 1000. A manual refill while idle and below a balance of 10 sets the integer wallet to exactly 1000. Fractional carry is preserved during this process.
Settled balance persists locally, including zero. An unfinished round ends on reload without refund or resume. Busy controls (Stake, mine count, and refill) are locked while the round is active. Eligible reveal cells and the bank button remain available.
Mathematical Evidence and RTP
The exact gross RTP is 0.96 across all modes. Simulation measurements are supporting sample observations, not the mathematical payout law. Below are observed exact values from the source-bound owner contract.
| Mines | Policy | Exact Gross RTP | Measured RTP | Gross Multiplier |
|---|---|---|---|---|
| 3 | 0 | 0.96 | 96.06732035820896 | 1.1319402985074627 |
| 3 | 5 | 0.96 | 95.43272228571429 | 151.68 |
| 4 | 0 | 0.96 | 96.01278254545456 | 1.2384415584415585 |
| 4 | 5 | 0.96 | 95.731904 | 572.16 |
| 5 | 0 | 0.96 | 96.06974783999999 | 1.3632 |

Privacy, Storage, and Audience
This guide targets an 18+ audience policy; it is not a claim about local law or an implemented age gate. The demo uses browser localStorage for settled balance and fractional carry. This does not establish anonymity or exclude other processing. The template declares a Google Fonts stylesheet; actual browser request capture is pending.
The demo has no account login flow and no payment flow. Virtual coins have no cash value. Clearing cached files may leave local storage where it is used. Terms explain this guide's own scope and do not invent legal releases or establish an outside company's policies.
Frequently asked questions
How is the board drawn in Anti Diagonal One Equality?
A four-by-four board is drawn uniformly from all boards with the selected mine count satisfying the exact public support rule: among the three neighbouring pairs along the anti-diagonal, exactly one pair has equal occupancy bits. Draws are uniform over that support, not over all unconstrained boards.
What is the formula for the gross payout?
After any safe reveal, the gross cashout is 96 percent of captured stake times initial support size divided by current compatible support size. Known-certain mines are disabled.
What happens when I hit a mine?
A mine ends the round with zero gross. The current quote is not banked unless no eligible cell remains or you manually bank after a safe reveal.
When can I manually bank?
Manual bank becomes available only after at least one safe reveal. You can also bank if all safe cells are revealed or if no eligible cell remains.
What is the stake cap?
Any safe reveal that would exceed the public 1000-times-stake cap is disabled. A cap guard disables individual above 1000x transitions before a reveal.
How do I refill my balance?
You can perform a manual idle-only refill. If your balance is below 10 and you are idle, the refill sets the integer wallet to exactly 1000. Fractional carry is preserved.
Does the balance persist if I reload the page?
Settled balance persists locally, including zero. However, an unfinished round ends on reload without refund or resume.
What is the exact RTP?
The exact gross RTP is 0.96 across all modes. Measured RTP values from simulation are supporting observations and may vary slightly.
Does the demo use localStorage?
Yes, the demo uses browser localStorage for settled demo balance and fractional carry. This does not establish anonymity or exclude other processing.
Is there an account login in this demo?
No. The demo has no account login flow. It is a browser-based demo owned by this independent guide.
Can I withdraw virtual coins?
No. Virtual coins have no cash value. There is no payment flow in this demo.
What is the intended audience for this guide?
The intended audience is 18+. This is a guide policy and not a claim about local law or an implemented age gate.
Is this the official in22 website?
No, this is an independent, unofficial guide. It does not host the game or process payments. You should log in to the actual in22 platform to play or deposit.
Do I need to pay to play this demo?
No. The demo uses virtual coins provided for free. You do not need to use GCash, Maya, or any other payment method to try the game.
