I don't know exactly how Eugene works, but I am quite sure like most chat bots it simply reacts to keywords or preprogrammed patterns. Basically it's Eliza [0], but with more scripts. I believe most people here would not give it credit for winning an intelligence test. There is actually more than one bot, which has been claimed to have passed the Turing Test before. Cleverbot is one of them [1]. There are also several competitions, but I believe the most reputable and long standing one is the Loebner Prize [2]. The bot that currently holds the Loeber Prize is Mitsuku [3]. Anyway, you can chat with Eugene at [4], I gave it a try. I believe there is one thing that the creators of Eugene got right. When chatting with other chat bots, I usually in a situation where the bot says something, I ask I followup question (like "Why?"), and it gives a generic answer like "Because I say so" or "I don't know". Eugene does the same but will ask a unrelated followup question right together with the response. That way at least there is not a weird pause in the conversation.
