==Consequences==

Players often have difficulty completing the specified number of drinks as the rate of consumption raises their blood alcohol content to high levels.<ref name="Reha">{{cite web |author=Bob Reha |date=May 26, 2004 |title=21st Birthday is a Deadly One |url=http://news.minnesota.publicradio.org/features/2004/05/26_rehab_colldrink/ |publisher=Minnesota Public Radio |access-date=2010-05-20 |archive-date=2011-06-29 |archive-url=https://web.archive.org/web/20110629135319/http://news.minnesota.publicradio.org/features/2004/05/26_rehab_colldrink/ |url-status=live }}</ref> The rate of alcohol consumption makes the players intoxicated within a short period of time.<ref name="Zernike">{{cite news |author=Kate Zernike |date=March 12, 2005 |title=A 21st-Birthday Drinking Game Can Be a Deadly Rite of Passage |url=https://query.nytimes.com/gst/fullpage.html?res=990DE0D8143CF931A25750C0A9639C8B63 |work=New York Times |access-date=2010-05-20 |archive-date=2012-11-10 |archive-url=https://web.archive.org/web/20121110013047/http://query.nytimes.com/gst/fullpage.html?res=990DE0D8143CF931A25750C0A9639C8B63 |url-status=live }}</ref>

== Trademark controversy == In 2010, Power Hour LLC, run by Steve Roose who markets a DVD game named "Power Hour", registered a trademark of the same name. Soon after, the company began sending cease-and-desist orders to Ali Spagnola, a musician who had released an album also titled ''Power Hour''.<ref name="pcpTM">{{cite news|url=https://www.pghcitypaper.com/arts-entertainment-2/can-a-drinking-game-be-trademarked-local-musician-ali-spagnola-hopes-not-1343746/|title=Can a drinking game be trademarked?
