Game Board

The Game Board consists of 16 poles in a 4x4 grid of positions. Each pole is capable to stack a maximum of 4 beads.

Game Mechanics

Four in a Row 3D is played in alternating players’ turns. The player controlling red beads moves first. In a player's turn he drops one of his beads onto a pole holding less than 4 beads.

Passing a turn is not allowed.

A player wins by forming a row of four own beads in any horizontal, vertical or even diagonal direction.

Have fun and enjoy the game…
