1. You can tell that she was unexperienced, there was learning (yes in one of the most popular games of civilization). She was playing against a not so difficult computer. She went from winning 25% of her games to winning around 50%.

2. The improvement came in the first 10-20 games. Given the low level of difficulty she could have improved way more, lot of untapped potential from the lady in the seat 47A.

3. Learning comes in many shapes and colors. In this case, one of my favorites: getting rid of bad habits. She over relied on the center box, habit she reduced over time.

4. There where hints of heuristical learning. She kept using the center in bad situations as well.

Concluding remarks: in the complexity scale of popular games, I am sure tic tac toe can be placed in the “not so complex” tier. However, even here I witnessed imperfect and heuristical learning. How is not reasonable to expect the same for all the more complex games???
