For readers in Pakistan, this means you are viewing a free demo with virtual coins. It is not the official gambling site, and no real money is involved in this specific demo experience. Always verify the actual operator's details separately.

What Players in Pakistan Should Check
Since gambling regulations in Pakistan are restrictive under national law, you must be cautious. This guide does not confirm if the actual b650 brand holds a valid licence for Pakistani users. You should check the operator's website directly to see if they accept Pakistani Rupees (PKR) or if you must use USD. Also, verify if they support local mobile wallets like JazzCash or Easypaisa, as these are common in Pakistan, but they may not be listed on the demo page you are viewing now. To check these details, look for the 'Payments' or 'Banking' section on the main operator site, not here. For safety, ensure you are an adult (18+) and play responsibly. Do not assume virtual coins in this demo represent real winnings. Always read the terms and conditions of the actual platform before depositing any real money.
- Verify PKR support and JazzCash/Easypaisa options on the operator site.
- Check if the brand is licensed to operate in Pakistan.
- Confirm you are 18+ and understand local gambling laws.
One Full Hazardous Row and No Full Column
Full Shelf Mines uses four rows and four columns. Choose five, six or seven total hazards. Exactly one entire row is hazardous and no entire column is hazardous. Other hazards are allowed subject to these conditions. The full row is hidden before play. There are respectively48,264 and864 legal full layouts. One layout is sampled uniformly and stays fixed for its round. Opened safe cells restrict the remaining legal layouts, so exact posterior safety probabilities may differ by cell and reveal history.
The initial gross collection value is 0.97 times the captured stake. For each unopened cell, count the remaining legal layouts compatible with all safe reveals. Its displayed safe probability is the proportion without a hazard in that cell. A safe reveal divides the current collection value by this exact probability. A hazard ends the round with zero return. The displayed percentage is rounded for reading; the payout uses the exact fraction. A proven safe cell has probability one and adds no multiplier. A proven hazard has probability zero and cannot be selected. A choice that would make the collection value exceed 1000 times the captured stake is disabled individually. Other eligible choices remain available. The game collects automatically when no eligible uncertain choice remains. Otherwise, collect after at least one safe reveal or choose another enabled cell. Every permitted stopping policy has exact unrounded expected gross credit of 97% of captured stake. This is not winning frequency or a guaranteed individual or session outcome. Conditional information changes available choices and quotes without raising expected return. The 0.97 factor is included once; settlement does not deduct another three percent.
Current Value and Conditional Probability
The initial gross collection value is 0.97 times the captured stake. For each unopened cell, count the remaining legal layouts compatible with all safe reveals. Its displayed safe probability is the proportion without a hazard in that cell. A safe reveal divides the current collection value by this exact probability. A hazard ends the round with zero return. The displayed percentage is rounded for reading; the payout uses the exact fraction.
Saved Wallet and Manual Refill
New local storage starts with 1000 virtual coins. Stakes are 10, 20, 50 or 100, with 20 selected initially. Starting deducts one captured stake. Settings and balance restoration are unavailable during a round. While idle with balance below 10, restoration sets the wallet to exactly 1000; it does not add 1000. Fractional payout carry remains saved across settlements and restoration. Coins have no cash value, prize or withdrawal route.
The settled wallet, including a zero balance, and fractional payout carry persist in this browser’s localStorage. Reloading ends an unfinished round without refund or continuation. A different browser, device or cleared site storage can have different saved counters. Clearing cached files alone may leave localStorage intact. The local wallet is not an operator account or synchronised financial balance.

Local wallet storage and network processing are separate.
