How Many Rounds Are in CS2? Full Breakdown of Match Formats

CS2 uses a 24-round format in Competitive and Premier (first to 13), and 15 rounds in Casual (first to 8).
Each round lasts around 1 minute 55 seconds, with halftime after 12 rounds in Competitive.
In pro play, overtime begins if the score reaches 12–12, usually in sets of 3 rounds per side until one team wins.

Overview — Why the CS2 Round System Changed

Valve replaced the old 30-round (MR15) format from CS:GO with a 24-round (MR12) system to make matches faster and more engaging. The goal was to keep CS2 competitive and viewer-friendly while maintaining its tactical depth. With fewer rounds, every decision — from economy to utility use — has a bigger impact, making each match more intense and strategic.
