Mysterious City: Vegas contains all the basics found in hidden object games: seek and find items from a list, compare to scenes for differences and make out silhouettes of objects. The game comes with two modes: relaxed and timed. Relaxed mode still has a timer that gives you 130 minutes. Not only that, but also using a hint takes away two minutes off the clock. While 100+ minutes is plenty, a clock ticking down doesn't make for relaxing play for some folks.
