If you can implement munstrum or any other strong connect four engine into it for hardest difficulty it would be perfect especially for practice play....ik its possible as there is a connect 4 app already on the market by puzzled jellyfish which uses velena and also many strong chess applications which run the top engines but other than that good app
Amazing I've tried out many versions of connect 4, by far the best. Great AI, puzzles, training, multi-player, skins, etc.
Love it Works great, straightforward.
tnx u sir.....
