Easy AI Accuracy: 5 / 5
Medium AI Accuracy: 35 / 35
Hard AI Accuracy: 100 / 100
The AI Attitudes for hard are 50/50 (the attitudes should add upto 100%). For easy/medium they still add upto 100%, but they are skewed more towards defensive. An even harder AI would be 80% aggressive / 20% defensive. To elaborate:
Aggresive Play
Aggresive moves are executed and intended to Flip the most cards potentially possible.
Defensive Play
Defensive moves are executed and intented to stop you from flipping any/least amount of cards.
There are "sub-attitudes" that are core-programmed within the AI, these are automatically determined based on Accuracy and Attitudes assigned, these are:
Aggresive-Defensive
The AI will take the most cards possible, but also maintain the best defensive position.
Defensive-Aggresive
The AI will choose the best defensive move possible, but in doing so try to flip as many cards as possible.
The sub attitudes seem the same, however as the names suggestion one attitude takes priority. Really the AI is fairly smart which it's intended to be, depending on how well you know the game will depend on your perfection of "difficulty". To me the Hard AI is a fair game, but I can beat it without much thought, to someone new to the game - it will feel like they are being slaughtered
