How the trainer works
Each mini-board is complete: there are no hidden neighbors outside its edges. Starting flags are proved mines. Reveal a square only when the visible clues guarantee safety, and flag a square only when they force a mine. This trainer asks you to account for every covered square, including the mines.
Left-click, tap, Enter, or Space uses the selected action. Right-click or F flags a square. Arrow keys move between squares. Incorrect moves leave the board unchanged so you can reconsider the reasoning.
Basics, Patterns, and Overlap train local deductions. Advanced adds larger frontiers with multi-clue chains. Expert includes mine-count endgames. The boards rotate and mirror so you practice the reasoning in different orientations. They develop recognition rather than timing you. Classic games can still require guessing; these small exercises always have a logical solution.
