3D Tic-Tac-Toe

How to Play 3D Tic-Tac-Toe

Game Objective

The objective of 3D Tic-Tac-Toe is similar to regular Tic-Tac-Toe, but in three dimensions: Get 3 or 4 of your marks (X or O) in a row - horizontally, vertically, diagonally, or in a 3D diagonal.

Game Board

The game is played on either a 3×3×3 or 4×4×4 grid. The grid has three coordinates:

  • X coordinate (horizontal position)
  • Y coordinate (vertical position)
  • Z coordinate (depth/layer)

Game Play

  1. Players take turns placing their marks (X or O) on the grid.
  2. Player X always goes first.
  3. To place a mark, click on an empty cell in the current layer view.
  4. You can switch between layers using the layer buttons above the grid.
  5. The game ends when a player gets 3 or 4 marks in a row (depending on grid size) or when the grid is full (draw).

Winning Patterns

There are many more winning patterns in 3D Tic-Tac-Toe than in the regular 2D version:

  • Horizontal lines (within a single layer)
  • Vertical lines (within a single layer)
  • Planar diagonals (within a single layer)
  • Vertical lines across layers
  • Diagonal lines across layers
  • 3D diagonal lines (corner to corner across the cube)

Strategy Tips

3D Tic-Tac-Toe is much more complex than regular Tic-Tac-Toe:

  • The center of the cube is a powerful position, as it's part of many potential winning lines.
  • Corner positions are part of 3D diagonals and can be strategic.
  • Keep track of all three dimensions - threats can develop across layers!
  • Be aware that there are many more winning patterns than in 2D Tic-Tac-Toe.
