A 4D 2-Player 3x3x3x3 Tic Tac Toe board! *******How To Play (a MUST READ if you've never played in 4 Dimensions!)******** In Normal Tic Tac Toe, there are two directions you can place tiles, an x axis and a y axis. The first to place 3 in a row (a straight line) wins! This can be extended to 3D with a cube. Think of the z axis as different layers of a cube, and it works the same as with the other dimensions. Place three tiles in a straight line vertical, horizontal, depth-wise, or diagonal to win. Since its on a 2D screen, we place the different layers of the square next to each other instead of on top of each other. Lastly, we add the fourth direction, "w". At this point, our intuition starts to break down. However, the rules we have applied before stay the same. All we need to do is place tiles so that they are in a "straight line," that is it has a constant change in its x,y,z, and w values. ********The BEST way to become fluent with 4 Dimensions is PRACTCE! Playing the game or just messing around placing tiles will help you figure it out best!*********
