Tic Tac Toe Toc
4D tic tac toe - based on game board created by Shayle Hirschman
Win detection has not been implemented
Tic Tac Toe Toc is an extrapolation of Tic Tac Toe, played on a 5 by 5 by 5 by 5 grid. The rules of play are generally the same. You win if you can create a line of five tokens of your color. The main difference is that Tic Tac Toe has two dimensions whereas Tic Tac Toe Toc has 5.
The 2D representation of the grid shown here is a grid of grids. In 'true' 4D representation, each row of smaller grids would stack on top of each other, coming out of the screen, forming five cubic grids, and those five cubic grids would stack on top of each other into the 4th dimension. If you know of a better way to represent 4 spatial dimensions within 2, in a web page, email me and I'll include it.
