39.4% win rate over 33 ladder games with 12 starting workers
Based on 33 games from 4 players · updated Nov 5, 2026
Across 33 ZvT ladder games from 4 players with 12 starting workers, 12 Pool wins 39.4% of decided games. The likely range for its true win rate is 24.7–56.3%, so it is too close to call against a coin flip. It appears in 1.5% of the 2,252 ZvT games in the guide sample. Its win rate is down 2.5 percentage points on the previous weekly snapshot. This is still a small sample (n = 33), so treat it as a directional read.
How to read these numbers
- Green: the whole likely range is above 50%
- Too close to call
- Red: the whole likely range is below 50%
Likely range: We're 95% sure the true win rate is inside this range. Fewer games means a wider range.
Openers are ranked by the low end of the range, so a few lucky games can't top the table.
A number appears once at least 5 players have played 30 games in it; a guide page needs 100 games.
Compared with a snapshot at least 7 days old; moves under 0.5 pp count as flat.
