However Large the Board, Explain These Five Cells First

A large Minesweeper board can create distance before thought. Your eyes travel; one promising clue disappears from memory as another region opens.

A popular Reddit large-board attempt drew an audience, but its app, dimensions, and record conditions are not interchangeable with our PROXX. Borrow a smaller question: how can a judgment remain checkable as the board grows?

Begin with five unknown cells, not the whole screen.

Combine a local relationship with a global fact

This is an original abstract exercise, not a screenshot. A through E are unresolved; everything elsewhere has been verified. Exactly two mines remain.

Reliable clues establish one mine in A/B and one in C/D. Those groups do not overlap. Together they account for both remaining mines. E, outside both groups, is safe.

Neither pair's individual mine is located. That uncertainty does not prevent determining E. A global count can exclude something elsewhere without first solving every local position.

Check whether you counted the same cell twice

Change the clues: one mine in A/B, and one in B/C. Do A/B/C necessarily contain two mines? No. The groups share B.

If B is a mine, A and C are safe: one mine total. If B is safe, A and C are mines: two total. Both assignments satisfy the local clues.

Adding the two 1s can count a possible mine twice. On a large board, regions that look separate in your notes may share a cell. Label cells or carefully follow the boundary to establish actual disjointness.

The remaining count needs evidence too

“Exactly two remain” is an explicit premise in the exercise. In a real interface, establish what the counter represents and whether mines already subtracted are confirmed.

Some displays simply subtract flags placed. Arithmetic does not correct a mistaken flag. You cannot guess two flags and then use the remainder to certify the guesses.

This article explains Minesweeper-style constraints. It does not promise identical marking gestures across current PROXX devices or make unverified claims about first-click protection and quick reveal. Follow in-game controls and actual adjacency.

Let one deduction supply the next information

Reveal a cell like E once justified, then inspect how new clues change the small region. Avoid mentally maintaining many unrecorded guesses while clicking.

When stuck, write that several assignments remain possible. Notes also reveal shared cells or unverified flags accidentally subtracted from a count.

A large board does not demand seeing everything simultaneously. It demands knowing why this small move holds. Explaining five cells can take you farther than scanning a screen faster.
