Diago: Get as many diagonal-aligned pieces as possible. Three in a row is 3 points, Four is 4 points, etc. Each column is filled from the top down. You are red, and playing against a random agent or a self-trained superhuman deep-q reinforcement network (select appropriate level to the left). You can get hints for next move - this is based on 1000 random plays and you can see the distribution of wins for each column played. Enjoy.
