How to Play Tic Tac Toe in 3D

Game Rules:

• Play takes place on a 3D cube with multiple layers
• Players take turns placing their marks (X or O) in any available space
• To win, you need to create three "tris" (three-in-a-row) in any direction
• Lines can be formed horizontally, vertically, or diagonally across any face or through the cube
• Think in 3D – winning combinations can span across different layers!

Unlock Center Mode:

Choose this mode at the start of each game for an extra strategic challenge!

• The center cell is locked at the beginning of the game
• It only unlocks after the first "tris" is completed
• This creates a strategic dilemma: make the first tris to gain an advantage, or hold back to secure the powerful center position?
• New strategies emerge: delay your first tris to claim the center, or rush for quick victories
• Every game becomes a unique tactical battle with multiple winning paths!
