3D Four in a Row takes the classic game into a cube. Instead of a flat board, you play on a 4 × 4 grid of upright poles, each holding up to 4 beads. If you’ve searched for 3D Connect 4, this is the game.
Rules
- Players take turns placing a bead on any pole that isn’t full.
- Beads drop to the lowest free spot on that pole.
- Make four in a line in any direction, including straight through the cube’s middle, to win.
Why it’s harder
A 4 × 4 × 4 cube has 76 winning lines, more than the 69 on a flat board, and many run diagonally through the middle of the cube. The four central poles are the most powerful.

Our online game plays the classic flat version: play classic Four in a Row to sharpen the skills that carry over to 3D.
