See Dota 2 Match Structure
Dota 2 is Valve’s multiplayer online battle arena game, where two teams contest lanes, objectives, and the opposing Ancient. Our market screen separates match winner, map winner, and series result labels before you make a selection. That distinction matters in a best-of-three fixture, because a map selection ends after one map while a series selection follows the complete scheduled contest. Availability depends
on local law.
