B650: No Account Portal on This Guide

No Account or Document Process

The demo does not require a password, one-time code, bank detail, identity document or account recovery. This guide provides no commercial verification or transaction-resolution service. A message using the B650 name does not establish that it represents a verified operator. No submission of documents or transfer of funds is needed to read these pages or use the original demo.

Publisher Evidence Limits

An external licensing claim would need evidence connecting the exact operator and domain to an independently checked authority record. A copied badge, HTTPS connection, successful small payment or favourable review alone cannot supply that connection. No such verified connection is provided here, and absence of evidence is not a conclusion that every similarly named service is genuine or fraudulent.

Package Evidence Limits

A filename, version label, file size or copied logo cannot establish who published a file. Matching a hash only establishes matching bytes when its reference source is independently trusted; it does not establish safe behaviour. This guide has no trusted B650 package reference or certificate to compare. It therefore gives no installation sequence, permission recommendation or claim that an external package is safe.

Requests and Processing Limits

Page loading requests Google Fonts and the Statinside analytics script. Hosting, CDN and third-party requests may disclose IP addresses, device details and request information to receiving systems. This guide does not establish anonymity, retention periods, absence of profiling or a data-sale policy for those systems. The demo has no registration, payment or identity-document form. Local wallet storage and network processing are separate.

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.
