## What is C43D?

A new dimension of strategy.   

C43D (pronounced "See Four in 3D") reimagines the classic four-in-a-row game in three dimensions. Stack your pieces on 16 pegs, connect 4 in a row — horizontally, vertically, diagonally, or through 3D space — and outsmart your opponent.
      
EASY TO LEARN 
  • Place pieces by tapping pegs. First to get 4 in a row wins. Simple rules, deep  strategy.

PLAY ANYWHERE 
  • Travel Mode — Board floats on screen, no surface needed
  • AR Mode — Place the board on any real surface
  • Rotate and tilt the board to see every angle

CHALLENGE YOURSELF
  • 2 Players — Pass and play with a friend
  • vs Computer — 4 difficulty levels from Easy to Expert

CUSTOMIZE YOUR GAME
  • 8 ball colors — Ruby, Amber, Emerald, Sapphire, and more
  • Adjust board size and position
  • Optional undo for casual play

BEAUTIFUL DESIGN
  • Handcrafted 3D models with a premium brass finish. No ads. No interruptions.  
  • Just pure strategy.                            
  • Based on an original tabletop game design.
