About this game

Light the safe runes and flag the mines in Grid Recon, a no-guess minesweeper puzzle you can play free in your browser — no download. You play LUMEN, a lantern-keeper on a haunted grid where every revealed number tells you exactly how many of that cell's eight neighbours hide a mine. From those clues you deduce which covered runes are safe and flag the ones that aren't. The promise that sets this apart: every board is generated to be fully solvable by pure logic from a guaranteed-safe opening, so a detonation is genuinely always a misread, never bad luck. Clearing a board doesn't end the game — it sends you one Depth deeper into a larger, denser, still perfectly fair grid, endlessly. You aren't punished by a single slip either: you start with three lives, and revealing a mine costs one life while leaving the rest of the board intact so you can keep deducing. Only losing your last life ends the run. Each cleared board banks ember toward Lumen's Reliquary, where permanent charms grant extra lives, Diviner hint charges that reveal a proven-safe rune, pre-placed flags, an Echo Charm that rewinds a fatal misclick, and a score multiplier. Pure logic, zero luck, deeply satisfying on phone or desktop.
