"""### 谜题描述

**Objective**: Clear a rectangular grid of hidden cells without detonating any mines. Cells contain either mines or numbers indicating adjacent mines.

**Grid Setup**:
1. The grid consists of hidden cells, some containing mines (randomly placed).
2. Non-mine cells reveal a number when uncovered, representing the total mines in the 8 adjacent cells (vertically, horizontally, and diagonally).

**Gameplay**:
1. **Uncover a Cell**: Click/select a cell to reveal its content:
   - If it contains a mine, the game ends (loss).
   - If it shows a number, use this to deduce nearby mine locations.
   - If it shows **0** (no adjacent mines), all adjacent cells automatically uncover recursively until numbered cells are reached.

2. **Flagging Mines**: Right-click/mark a cell to flag it as a suspected mine (prevents accidental uncovering). Flags help track potential mines but do not affect gameplay logic otherwise.

**Win Condition**:
- All non-mine cells are uncovered, and all mines are correctly flagged.

**Logic Rules**:
- Numbers on the grid are **static hints**, not live updates. Flagging a mine does not change existing numbers.
- Use the numbers to infer mine positions: e.g., a cell labeled \"3\" must have exactly 3 mines in its 8 neighboring cells.

**Loss Condition**:
- Uncovering any cell containing a mine.
