Independent Scope
OP16 is a search label, not an operator identity established by this guide. op16.cc is an independent information guide with its own Bishop Clearance Mines demo.

Fixed Diagonal-Clear Layouts
Bishop Clearance Mines uses a four-by-four board. Choose 3, 4 or 5 hazards before starting. No two hazards share any chess diagonal, including separated cells. The three presets have exactly 232, 260 and 112 legal layouts respectively. One layout is chosen uniformly and remains fixed during the round; hazards are not moved after a reveal.
Exact Conditional Safe 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.
Collection and the 1000× Guard
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.
Virtual Wallet and Restoration
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.
Expectation and Its Limits
The exact unrounded expected return is 97% of captured stakes for permitted stopping policies. This is an expectation over repeated play, not a promised session result. The diagonal constraint changes conditional probabilities after a reveal; it does not identify the hidden layout in advance. Neither guessing a pattern nor changing stake increases that expected return. These probabilities belong only to this original demo.
