📖 Tic-Tac-Toe (Infinite 3-Mark Edition) — Rules

🎯 Objective

Get 3 of your marks (X or O) in a horizontal, vertical, or diagonal line—with no cat's game ties!

🕹️ How to Play
  • Take turns tapping an empty square on the 3×3 grid to place your X or O.
  • Once you have 3 marks on the board, your oldest mark pulses/fades to warn you it will vanish next.
  • When you place your 4th mark, your oldest mark is automatically removed from the board!
📏 Key Rules & Scoring
  • ♾️ No Draws: Because each player never has more than 3 marks on the grid, the board never locks into a tie.
  • 🧠 Memory & Traps: Keep track of which mark your opponent is about to lose so you can block their lines and set up two-way forks!
