Used to play this with my grandma when I was a kid, lots of fun. The scoring tally is not revealed, though, and it is unclear how to improve. Sometimes three fast rounds with good bonuses have a lower score than closer games. Also, is there a war to improve the skill of the bot?
Sorry the score method is not revealed but is probably related to how well you do compared to the bot but also time related 
There is no way to improve the bot. We will soon add a Cat and Mouse game with better AI.
