Rush Hour (board Game)
Rush Hour is a sliding block puzzle invented by Nob Yoshigahara in the late 1970s and first sold in the United States in 1996. It is manufactured by ThinkFun (formerly Binary Arts).
ThinkFun now sells Rush Hour spin-offs Rush Hour Jr., Safari Rush Hour, and Railroad Rush Hour, with puzzles by Scott Kim. An iOS version of the game has been released in 2010 with both free and paid versions (the latter with more puzzles and features).
The regular version comes with 40 puzzles split up into 4 different difficulties, ranging from Beginner to Expert. The deluxe edition has 60 puzzles and has an extra difficulty, the Grand Master, which is harder than Expert. Puzzles falling in this difficulty range can only be sold with expansion packs of the original game. The regular version includes a travel bag. Extra puzzle card packs (in addition to the 40 or 60 cards included with the game) are also available. The deluxe edition also comes with shiny cars.
When generalized so that it can be played on an arbitrarily large board, the problem of deciding if a Rush Hour problem has a solution is PSPACE-complete.

Famous quotes containing the words rush and/or hour:
“When words fail us or, quite the opposite, when they rush from our mouths faster than we would like, we can console ourselves that if no single moment is going to define our relationship with a child, neither can a single lapse of good judgment or patience destroy it.”
—Cathy Rindner Tempelsman (20th century)
“Never invite to dinner: those who won’t decide until the last minute; those who come more than half an hour late; those who want to bring along two or three friends; drunks; monologists; those who stay until three o’clock in the morning; those who think that conversation means having an argument; those who take a high moral tone; those who are stupid, ugly, or dull. Enforcement of these rules will enable one to eat alone every night in comfort.”
—Mason Cooley (b. 1927)
