# Mine-Seeker Bonus Points System

## Overview
The Mine-Seeker game includes a bonus points system that rewards skilled play. Bonus points are tracked separately from the main score and displayed in the "Bonus Statistics" dialog.

## Bonus Point Types

### 1. Blind Hit (+2 points)
**When**: Click a mine with no revealed numbered neighbors around it.

**Example**: Mine surrounded by unrevealed cells = +2 points

---

### 2. Chain Combo
**When**: Click consecutive mines without clicking any safe cell in between.

**Tracked as**:
- `chainCurrent`: Current streak (resets when you click a safe cell)
- `chainBest`: Longest streak achieved

**Example**: Mine → Mine → Mine = chainBest becomes 3

---

### 3. Edge Mine (+1 point)
**When**: Click a mine on the board boundary (row 0, row 15, col 0, or col 15).

**Example**: Click a mine on the edge = +1 point

---

### 4. Endgame Mine (+3 points)
**When**: Click a mine when 10 or fewer mines remain on the board.

**Calculation**: `51 total mines - (red_points + blue_points) = mines_remaining`

**Example**: When 8 mines remain, click one = +3 points

---

### 5. Safe Cell Bonus (+0.5 points per cell)
**When**: Click a safe cell and reveal 2 or more cells.

**Important**: Minimum 2 cells required. Single cell reveals = 0 points.

**Examples**:
- Reveal 1 safe cell = 0 points
- Reveal 2 safe cells = 1.0 points
- Reveal 11 safe cells = 5.5 points

---

### 6. Biggest Reveal (Tracking stat)
**What**: Tracks the largest number of safe cells revealed in one click.

**Example**: Largest reveal in a game = 15 cells shown in stats

## Bonus Statistics Display

### Dialog Shows
- Both players' bonus statistics side-by-side
- Each stat with label, description, and value
- Total bonus points per player

### Player Name Rules
- `anon_*` usernames → displays as "Anonymous"
- Names longer than 10 chars → truncated to 7 chars + "..." (example: `VeryLongName` → `VeryLon...`)
