The computers programmed on this website

I've lost over 100 points in 1 night playing against these slot machine computers. I was actually down close to 200 points last night too. 

Whoever would program this stuff for educational purposes is honestly sick. It's sacrificing pieces left and right, and playing on some type of rubber band algorithm, where it chooses when to win and lose.  

 I've also countless times had pieces clip into the wrong square or not go into the square at all when I try to move them. This has caused me to lose on increment or blunder pieces completely. I never have this problem on other websites. I do admit I play less 1 minute elsewhere. 

 Back on the note of the computer.. I wonder if this is a violation of fair play policy guidelines on the website; the way it is programmed.
