Two roles, one board, and a twist, either player may drop an X or an O, so the battle is over a line of five, not over a colour.

How to play
On a 6x6 grid the two roles share both symbols. On any turn you choose to place an X or an O in an empty square, and the roles want opposite outcomes.
Order wins by forming five identical symbols in a row, horizontally, vertically or diagonally.
Chaos wins by filling all 36 squares without any line of five appearing.
Because both sides can play either symbol, blocking and building are constant trade-offs.
Order moves first, then turns alternate until someone's goal is met.

2-player pass-and-play on a single device.
Online play: host an invite, join with a code, or quick-match, the host plays Order and the joiner plays Chaos.
Tips & strategy
As Order, build two open threats at once so Chaos cannot plug both with one move.
As Chaos, drop the opposite symbol into a forming run to break it before it reaches five.
Five-in-a-row only needs five of six in a line, so guard the long central rows and columns carefully.
Origins
Order and Chaos is a tic-tac-toe variant with a precise origin: Stephen Sniderman invented it and introduced it in Games magazine in 1981.
Its innovation is asymmetry of purpose rather than of material. Both players place both symbols on a 6×6 board — anyone may play an X or an O on any empty square — so the two sides are not distinguished by what they control but by what they want.
Order is trying to build five in a row of either symbol; Chaos is trying to prevent it. That makes it one of the few abstract games where the players are not doing the same thing to each other, and where helping your opponent's material can still serve your own goal.
