tl;dr: Reverse Minesweeper is a Minesweeper variant with a difficulty system driven by a logic engine that solves each generated grid using the simplest available deduction, classifying puzzles into five tiers (Easy, Medium, Hard, Extreme, Insane) based on the hardest technique required—from single-clue deductions up to Sudoku-style forcing chains and "either-way" coloring. Sliders let players tune minimum deduction counts and chain depths per tier, and a 0–100 score positions grids within non-overlapping difficulty bands, with estimated solve times computed from per-technique time weights.
