My demo-mode is implemented using a simple evaluating function. Experiments with neural-networks have been done, they rather provide minor results. The results I obtained with my game are a mean score of 675 lines (for 50 games) and a top at 3809. The results obtained by using a neural-network provide a mean score about 100 lines with tops greater than 500 lines. The (human) world champion reached the score of 900 lines ! If you reach the score of 100 lines, without any difficulty, you are considered as an expert player. If you ever write a similar program that gives better results, let me know!
