The main destination for thrill ride junkies is The Adventuredome at Circus Circus, which features the world's only indoor double-loop, double-corkscrew roller coaster, The Canyon Blaster (shown).
The 4 o'clock spot is a Master button (for saving settings and quickly returning the center dial to its main volume control), and 6 o'clock features a half-dozen blocks that correspond to your virtual surround speakers.
