The Monopoly Mystery

The Monopoly Mystery | Science Fair Projects | STEM Projects
Can a computer's personality determine who wins the game of Monopoly? To find out, an experiment was conducted with two different AI players, Type A and Type B, and a Random AI player. After 300 games, the results showed that Type B had the best playing strategy when all 3 AI players were playing.


The hypothesis is that the more aggressive AI player, Type A, will win more games.

Method & Materials

You will program variables into Type A and B AI players with the help of personality profile research. You will have the computer play 300 games; the first 100 with a Random AI player, the second 100 with a different Random AI player and the third 100 acting as a control with Type A and B players only.
You will need a computer, programming software, and research on personality profiles.


The experiment showed that both probability and personality play a significant role in who wins or loses the game and that trading is very important. Also, 3 player games are much more complex and in-depth than 2 player games. The results indicated that the Type B AI player had the best playing strategy when all 3 AI players were playing.

Why do this project?

This science project is interesting because it shows how personality can affect the outcome of a game.

Also Consider

Experiment variations to consider include changing the number of players or the type of AI players used.
