in22 Demo Guide: Anti Diagonal One Equality Rules & Math

This guide explains the mechanics of Anti Diagonal One Equality, a four-by-four Mines game where board validity is determined by a specific anti-diagonal constraint. Unlike standard Mines variants, this demo uses a uniform draw from a filtered support set. The payout depends on the shrinking support size rather than simple cell counts.

Below, you will find the exact rules, the mathematical evidence, and answers to common questions about controls, wallets, and privacy. Please note that this is an independent guide for the in22 demo platform.

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 Malaysian Players Should Check Before Playing

As a player in Malaysia, you should verify a few key details before engaging with the in22 demo. First, confirm whether the platform supports transactions in Malaysian Ringgit (MYR) or if it uses a different currency. Second, check if local payment methods like Touch 'n Go eWallet or DuitNow are available for future real-money play, as these are the most common digital wallets in Malaysia.

It is also important to remember that gambling is tightly restricted by national law in Malaysia. While the demo uses virtual coins, any real-money activity may depend on specific state laws or exemptions. Always check the operator's terms to see if they hold a valid licence that applies to Malaysian residents. For safety, ensure you are using the correct website address and verify their customer support channels.

  • Check if the balance is displayed in MYR.
  • Verify if Touch 'n Go eWallet or DuitNow are listed as deposit options.
  • Confirm the operator's licensing status for Malaysia.
  • Ensure you are over 18 years old.

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.

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.

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 the in22 demo free for Malaysian users?

Yes, the demo uses virtual coins and does not require a deposit. However, verify if the operator offers real-money play in Malaysia, as gambling laws are strict.

Does in22 support Touch 'n Go eWallet?

This is not confirmed. You must check the 'Payment Methods' or 'Banking' section on the official in22 site to see if Touch 'n Go eWallet or DuitNow are supported for Malaysian users.
