Deduce hidden hazard locations across Beginner (9×9), Intermediate (16×16), and scrolling Expert (16×30) sectors with safe first moves and touch controls.
The logic of numerical indicators, safe opening mechanics, and essential pattern recognition rules for zero-guess solving.
Welcome to Mine Finder, a modern logic puzzle designed to test deductive reasoning, spatial analysis, and probabilistic decision-making. Whether you are navigating the introductory Beginner sector or sweeping the sprawling 30-column Expert grid, every uncovered cell brings you one step closer to clearing the hazard field.
The core objective is discovering and flagging every hidden hazard without triggering an accidental detonation. Each sector starts completely covered. On your very first move, the system provides a safe opening: neither your clicked coordinate nor any of its immediate surrounding neighbors can contain a hazard. This opens an expansive initial clearing and triggers an automatic recursive flood-fill across all contiguous blank terrain.
Every revealed cell displays a numerical indicator from one through eight representing exactly how many hazards touch that specific square horizontally, vertically, or diagonally. By cross-referencing overlapping numbers, you can logically isolate where hazards must reside and where neighboring ground is safe to clear.
When you encounter numbers one, two, and one in a straight row along an unrevealed perimeter wall, the hazards invariably lie directly beneath the two ones, while the space under the middle two is safe to clear.
In this common configuration along an unexplored border, the two hazards reside directly beneath the two middle twos, leaving the spaces underneath both ones completely clear for immediate progression.
Identify cells shared between adjacent numbers. If an unrevealed cell satisfies the requirement of a neighboring number, subtract its constraint to safely unlock surrounding mystery squares without guesswork.
The Expert sector features a wide 16-row by 30-column matrix containing 99 hazards. On smaller smartphone screens, the arena stays contained inside an independent horizontal scrolling viewport, keeping each cell comfortably sized for precise finger taps.
Use the dedicated Flag Mode toggle button or simply hold down on any tile for 350 milliseconds to plant warning flags with subtle haptic vibration feedback. Tapping an already uncovered number cell automatically clears surrounding non-flagged neighbors when adjacent hazards have been flagged (Quick Chord).

Key answers regarding rules, controls, and features for Mine Finder.
Your first action is designed to be safe. The generation engine delays placing hazards until after your initial click coordinate is registered. It constructs an exclusion perimeter around that point, ensuring the starting tile and all surrounding neighbors are completely empty, initiating an immediate cascade flood-fill.
Mine Finder offers dual touchscreen controls tailored for mobile precision. Toggling Flag Mode switches standard tapping from uncovering cells to planting hazard markers. Alternatively, you can keep standard reveal mode active and simply hold down on any tile for 400 milliseconds to trigger a long-press flag with subtle haptic vibration feedback.
These classic mathematical patterns exploit shared overlapping constraints. In a 1-2-1 sequence against an unexplored edge, the center two requires two hazards, but each flanking one only permits a single hazard in its reach. The only algebraic combination that satisfies all three conditions concurrently places hazards on the outer ends.
Once you have flagged the exact number of neighboring mines indicated by a revealed number cell, clicking or tapping that number cell executes a chord reveal, instantly clearing all remaining unflagged adjacent squares.
