Xterious offers an escape from partying and gambling for those of you who need a bit of a break. It's just behind the Tropicana, a couple blocks off the strip, so an easy walk or short drive depending on where you're staying. We did the Bugsy room which had a gangster/bootlegger theme and it was a lot of fun and a good challenge (without being too difficult).
Our group was able to escape without any clues in 49 minutes. Unfortunately, we didn't make the leader board as those with better times had used clues. It would be nice if they had a separate leader board for teams that don't use the walkie-talkies to get any clues.
