To find out what stairs you can currently challenge someone in, first go to the Main Stairs Page, then click on "Show your stairs only" link. The ones in BOLD are ones you can make a challenge in. .
S O C R A T E S: My suggestion to anyone who hates to play lower rated players and only want to play same rated players, then stairs may not be the best thing.
Unless you want to stay around long enough to climb the stairs - then once a stairs spread out some and you are near the top, then you will only have to worry about being challenged by players close to you - which most likely will also be higher rated players.
