Something like tic-tac-toe, but with sub-fields (a 3*3 grid for every square in the main board, maybe another layer beneath for a really long game) that you have to win to "gain" the larger square (put you mark on it, either an X or an O).  Maybe some fighting/arcade (or perhaps a random medley of simple arcade games) aspect or something fought against an AI or another player to gain the squares in the sub-fields can be added, or it could just be pure strategy.  Game is won if user gets three of their X/O in a row in the master grid.

You have to solve the problem in Tic-Tac-Toe explained in War Games somehow.

Can you elaborate on what that is a bit?  TIA

And yeah, this is going to be interesting to code.  I'm starting by making the little mini-games that'll determine the ownership of a square.  So far I've made a simple pong game, under 820 bytes

I'll need to read up on how to do a sort of SHUMP, and idk what else from there.
What the hard part is is finding really simple games, easily made 2-player, which are small and fit into the contest rules, I'm not sure pong is one of those but oh well
