An 8-ender in curling is just like a perfect game in baseball or a hole-in-one in golf or a perfect 300 in bowling or a nine-dart finish in darts!!! It's a feat so rare the odds of scoring one is nearly impossible to know.

An eight-ender occurs when a team scores eight points in a single end of curling. Curlers who achieve this feat are listed in the American Curling Foundation & Museum. Eight-enders are so rare that USA Curling recognizes all teams that accomplish this feat with an eight-ender patch.
