=== Sleeping ===
<!--[[Sleeper (a yo-yo trick)]] redirects directly here.-->
The sleeper is one of the most common yo-yo throws and is the basis for nearly all yo-yo throws other than [[#Looping (2A)|looping]]. Keeping a yo-yo spinning while remaining at the end of its uncoiled string is known as sleeping. While the yo-yo is in the "sleeping" state at the end of the string, one can then execute tricks like "walk the dog", "the elevator", "around the world", or the slightly more complex "rock the baby".

The essence of the throw is that one throws the yo-yo with a very pronounced wrist action so that when the yo-yo reaches the end of the string it spins in place rather than rolling back up the string to the thrower's hand. Most modern yo-yos have a transaxle or [[ball bearing]] to assist this, but if it is a fixed axle yo-yo, the tension must be loose enough to allow this. The two main ways to do this are (1), allow the yo-yo to sit at the bottom of the string to unwind, or (2) perform lariat or UFO to loosen the tension. When one decides to end the "sleeping" state, one merely jerks the wrist and the yo-yo "catches" the string and rolls back up to the hand. Ball-bearing yo-yos with a "butterfly" shape, primarily used for string tricks, frequently have a low response or are completely unresponsive, requiring a "bind" for the yo-yo to return.

In competition, mastery of sleeping is the basis for the 1A division. Inexpensive fixed-axle yo-yos usually spin between 10 and 20 seconds, while the expensive ball bearing yo-yos can spin about 1–4 minutes depending on the throw.<ref>[http://entertainment.howstuffworks.com/yo-yo-basics2.htm Yo-Yo Basics], [http://entertainment.howstuffworks.com howstuffworks.com].</ref> {{as of|2010}}, the world record sleep times were 3:51.54 minutes for fixed-axle and 21:15.17 minutes for transaxle yo-yos.<ref>[http://ayya.org/ American Yo-Yo Association] website.</ref> In 2012, the transaxle yo-yo sleep time record was broken by the C3YoyoDesign BTH, with a time of 30:28.30 minutes.<ref>{{Cite web |title=Museum of Yo-Yo History |url=http://www.yoyomuseum.com/museum_view.php?action=view&subaction=exhibit&exhibitid=2151 |access-date=2024-06-05 |website=www.yoyomuseum.com}}</ref> A traditional sleeper throw is employed to start frontstyle combinations, whereas a sideways sleeper, or "breakaway" is used to start sidestyle combinations.
