Useless. Very very easy. And when it says "CHECK". Unbearable. Edit: to reply, yes, the hard level is actually not hard. I played the 3 levels. The "check" pause is very annoying. Just to let you know. Check is not that important.

Hi, Please consider that this is a Mini Chess game, not at all comparable to a standard Chess in terms of difficulty. We still offer 3 levels of AI. Have you tried the harder one? Anyway, we would love to hear about your feedback. If you want to write more, please drop us an email to support@outofthebit.com.
