It sounds like you're describing a game of checkers (also known as draughts)! Here's a quick summary of how it works based on your description:

🎮 How to Play Checkers:

• Players: 2 (you can play against:

  • The computer (single-player mode),
  • A friend on the same device (local multiplayer),
  • Or an opponent over the internet (online multiplayer).

• Board Setup: A standard 8×8 checkerboard with 12 pieces per player, placed on the dark squares of the three rows closest to each player.

• Movement:

  • On your turn, move one of your checkers diagonally forward to an adjacent empty square.
  • Regular pieces can only move forward (toward the opponent’s side).

• Capturing:

  • You can capture an opponent’s piece by jumping over it diagonally to an empty square immediately behind.
  • Captures are mandatory — if you can capture, you must.
  • You can make multiple jumps in one turn, as long as they are in sequence and followed by another capture opportunity.

• Kinging:

  • When a piece reaches the farthest row (opponent’s back row), it becomes a king.
  • Kings can move diagonally forward and backward.

• Winning:

  • The game is won by capturing all of your opponent’s pieces, or by blocking them so they cannot move (stalemate).

🔁 Tips:

• Always look ahead: Plan your moves and potential captures.
• Try to control the center of the board.
• Avoid leaving your pieces vulnerable to capture.
