Equal Counts in Occupied Columns

Column Quota Mines has a four-by-four board. Select four, six or eight TOTAL hazards before starting; these are not hazards per column. Every column containing hazards must have the same positive hazard count as every other occupied column. A column may contain no hazards. There are respectively 476, 960 and 1302 legal full layouts. Each is uniformly selected once and remains fixed during its round.

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.

Collection and Disabled Choices

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.

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.

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.
