SK7: Query Identity and Original Demo

Independent Query Guide

SK7 is a search label, not an operator identity established by this guide. getsk7.com is an independent information guide with its own Residue Quartet 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.

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.

Equal Hazard Totals in Four Coordinate Classes

Residue Quartet Mines uses a four-by-four board with row and column indices 0 through 3. A cell belongs to class (row + 2 × column) modulo 4. Each of the four classes contains four cells. Choose four, eight or twelve TOTAL hazards: every class must contain exactly one, two or three hazards respectively. There are 256, 1,296 and 256 legal complete layouts respectively. Hazard positions within each class are sampled uniformly; they are not determined solely by class membership. One whole layout is hidden and fixed throughout the round. Revealed safe cells restrict the remaining layouts and update conditional probabilities.

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 neither winning frequency nor a guaranteed individual or session result. Conditional information changes choices and quotes without raising expected return. The initial 0.97 factor is applied once; no second three-percent deduction occurs.
