Thanks... I used a php middle tier with a mysql back end. The client contains the ids for the computer players, but the logic is server side (as are the questions, etc). Construct 2 has worked very well for creating the front end. Although I am still not at the level of using its more advanced features... I am working towards that. I think writing the questions took longer than the programming LOL ;-)
As for the logic itself... the players all have 3 possible values for both speed and knowledge.
Basically once the php script retrieves their knowledge value it then scans each possible answer... just like a real player would. Each time it looks at an answer it "rolls" to see if it can tell if its right or wrong. If it fails to roll low enough then it will randomly decide to click it or not (50/50 at that point). If not then it moves to the next answer and so on. There are 3 levels of knowledge.. smart is 80/100, medium is 50/50, and dumb is 20/100. If it does roll low enough then if the answer is correct it will select it, or pass it if it is wrong. It repeats this until it locks onto 5 answers.
