Column Lex Zigzag: Rules, Math, and Demo

The board has 4×4 cells and exactly 3, 4 or 5 mines. Read each column from top to bottom as a four-bit integer: mine = 1, safe = 0, weights 8, 4, 2, 1. From left to right, the column values must satisfy c0 ≤ c1 ≥ c2 ≤ c3; equality is allowed. Draws are uniform among boards satisfying both this rule and the selected mine count. Initial support sizes are respectively 150, 464 and 1053. Revealing a safe cell filters the compatible support.

After a safe reveal, gross quote = 0.96 × captured stake × initial support / current compatible support. The stake is deducted when the round starts. A mine returns zero gross. Manual banking is available after at least one safe reveal. Certain mines and cells whose safe quote would exceed 1000× stake are disabled. All safe cells revealed or no eligible cell remaining automatically banks the current quote. A certain-safe cell can remain eligible. With five mines, singleton support would quote 1010.88×, so that above-cap transition is disabled.

When playing the AQ9 Column Lex Zigzag demo, Indian readers should note that this is an independent informational site, not the official operator’s platform. While the demo uses virtual coins, real-money versions may involve INR. You must check with the operator directly to confirm if they accept Indian Rupees and support local payment methods like UPI, Paytm, or PhonePe. Also, verify the regulatory status, as gambling laws in India vary by state. For safety, always confirm the app’s licensing details on the operator’s official site before depositing real money. Responsible play is key, especially since legality depends on your local jurisdiction.

• Confirm if INR is supported for real-money play.
• Check for UPI, Paytm, or PhonePe options with the operator.
• Verify state-wise gambling legality and licensing.

The payout is calculated dynamically based on the shrinking support set. The formula for the gross quote is:

Cells with zero conditional safe probability are disabled. Cells whose safe quote would exceed the 1000× stake cap are also disabled.

Choose a stake and 3, 4 or 5 mines before starting. During the round, stake, mine count and refill are locked; sound remains available. Choose an eligible covered cell. Manual banking is an option after at least one safe reveal. All safe cells revealed or no eligible cell remaining settles automatically. A mine loses the captured stake. There is no auto queue.

The demo wallet operates independently of any external account.

• Initial Balance: 1000 virtual coins.
• Restoration: Manual idle-only refill sets the balance to exactly 1000 if below 10. It does not add coins; it sets the total.
• Fractional Carry: Persists across settlement, refill, and reload.
• Unfinished Round: Reloading during an active round ends it without refund or resume.

The exact gross RTP is 0.96 across all modes. Measured RTPs are sample observations and not promised session results.

The demo stores balance and fractional carry in browser localStorage. It has no account or payment form; this does not establish anonymity or exclude other processing. Pages request Google Fonts and Statinside counter 44. Those requests may convey the IP address and browser request information to those services. Server retention and other processing are not established here. Clearing this site’s localStorage or site data removes balance and carry; clearing only cached files may leave them intact.
