Initially, we only designed the version of two players. AI function had been added later. We asked for trouble unexpectedly as we added AI function. It’s not easy to write the original AI artificial intelligence. The first version of AI is not smart because we try to prevent AI cheating and let AI make decision only base on the current information and the situation that have occurred. So, many users complained about AI on Android market at the beginning. Frankly speaking, we suffered from it and dared not to check the message from Android market at that time. Then, we realized such a high requirement for the free version and upgrade version around end of May. This time, we did our best to improve AI even it is still not smart enough. Interestingly, some users turn to complained AI is getting smarter and cheating. We take it as compliments.
We will not have much upgrade for AI afterwards because human brains are always smarter than AI. The only thing we considered is to do the version of online game next year. It may be more interesting to let human brains fight each other.
