Choose a Stopping Time
Choose a personal time or virtual-coin boundary before starting and stop when it is reached. A restored balance is optional and does not make further rounds necessary. The demo does not enforce a timer, diagnose behaviour or provide account exclusion. Taking a break does not change future hidden layouts or raise the expected return.
Scope of This Guide
These pages describe this guide’s scope and its original demo. They do not rank an external business, confirm financial reliability, provide a legal opinion or establish permission to gamble in any country. External activities have rules and eligibility requirements that this guide has not verified. The original demo does not reproduce an external product’s interface or odds.
Identifiable Local Assistance
If play is becoming difficult to stop or affecting daily responsibilities, close the demo and consider qualified local support. No B650 help line, account-blocking feature or treatment service is verified by this guide. Its pages do not diagnose a condition, give treatment instructions or substitute for an appropriate professional service.
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.
Expected Gross Credit
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.
Frequently asked questions
Is an operator verified?
B650 is a search label, not an operator identity established by this guide. playb650.com is an independent information guide with its own Full Shelf Mines demo. No company, licence, official account domain, commercial game catalogue, payment service, app publisher or support contact is verified here. Search position, a similar name and page appearance cannot establish those facts.
What makes a layout legal?
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.
How does collection value change?
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.
