## Overview
Connect the Dots is a puzzle game where players must connect numbered dots in sequential order while filling every cell on the grid. The game features multiple levels with increasing complexity, including boundary walls that restrict movement.

## Objective
The primary goal is to **connect all numbered dots in sequential order (1→2→3→4→5→6→7→8) AND fill every cell on the grid**. Simply connecting the numbers is not enough - you must visit every cell exactly once.

## How to Play

### Basic Movement
- **Adjacent Cells Only**: Move only to cells directly above, below, left, or right of your current position (no diagonal movement)
- **Sequential Numbers**: You can only connect to the next number in sequence (1 connects to 2, 2 connects to 3, etc.)
- **No Revisiting**: Each cell can only be visited once (except during undo operations)

### Game Flow
1. **Start**: The game begins with your path starting at number 1
2. **Connect**: Move to adjacent cells containing the next number in sequence
3. **Fill Grid**: Continue moving through empty cells to reach subsequent numbers
4. **Complete**: Successfully connect all numbers while visiting every cell

## Win Conditions
You win the level when you:
- ✅ Connect all numbers in sequential order (1 through n)
- ✅ Visit every cell on the grid exactly once
- ✅ Have no remaining valid moves

**Reward**: 100 points added to your total score

## Lose Conditions
The game ends in failure when:
- ❌ Connect to a number that's not the next in sequence
- ❌ Get stuck with no valid moves available (no adjacent cells to move to)
- ❌ Cannot reach the next number without violating the rules
