Counter-Strike 2: esports statistics
Rounds, map pool and overtime across the big tournaments.
What decides a CS2 map: average and expected rounds with the probability of clearing each line, how often it goes to overtime, whether starting on CT pays off, and every team's map pool. We give you the number; you find the value against whatever odds you are offered.

The full pool, map by map: how long they run, how often they reach overtime and whether starting on CT is a real edge.

| Cache | 88 | 21.8 | 4.7 | 12.5 % | 53.4 % |
A map ends as soon as someone reaches 13, so the average always sits around 22. What is informative is the deviation (tighter or more one-sided maps) and the overtime rate.
