Welcome to Reversi (Othello) – v1.0.3
🎮 A game of strategy, precision, and the occasional underhanded move.

🎯 Objective

Outmaneuver your opponent by placing your discs to surround and flip their pieces. The player with more discs of their color on the board when it's full wins.

📦 Game Setup

• Board: 8×8 grid (like a chessboard).
• Pieces: Black and White discs (one player takes Black, the other White).
• Starting Position:
  • The center four squares are pre-filled:
    • Top-left: White
    • Top-right: Black
    • Bottom-left: Black
    • Bottom-right: White
      (So: W B on row 4, B W on row 5)

🔄 How to Play

1. Players alternate turns, starting with Black.
2. On your turn:
   • Place one of your colored discs on an empty square.
   • Must surround at least one opponent’s disc in a straight line (horizontal, vertical, or diagonal).
   • You flip all opponent discs between your new disc and any of your existing discs in that line.
3. No illegal moves: You cannot place a disc unless it results in flipping at least one opponent piece.
4. Passing: If you have no legal move, you must pass. The game continues until both players pass consecutively — then it ends.

🧠 Strategy Tips (Pro-Level)

• Corners are gold: Once captured, a corner can never be flipped. Control them early.
• Edges matter: Discs on edges are harder to flip than center ones.
• Avoid the center early? Not always — but don’t place in the center unless you’re ready to commit.
• Think ahead: Every move can flip multiple pieces — plan for traps and reversals.
• Don’t get greedy: Flipping many pieces might leave you vulnerable later.

✅ Win Conditions

• The game ends when:
  • The board is full, or
  • Both players pass in a row (no legal moves left).
• Winner: The player with more discs of their color on the board.

🏆 Tie? If both have 32 discs, it's a draw.
