Love the fact that you're bringing out skill-based games, we definitely need more of these as far as I'm concerned.

However, I think this four-in-a-row game is just asking to get botted. There are AI tools available online that will automatically solve for the best possible combination given the current state of the board.

I really think you're going to need to make games that people absolutely cannot cheat on, otherwise the losers will not be happy.
