The number of episodes varies by version of The Traitors you’re asking about. Here are the current counts for the main formats:

• The Traitors (American TV series, US version): Season 1 had 11 episodes, and Season 2 had 12 episodes (total across both seasons listed as 23 episodes in the era you referenced).

• The Traitors (British/UK version): The standard British series typically runs around 10–12 episodes per season, with recent seasons often set at 12 episodes, though exact counts can shift between series. For example, the UK BBC’s listing shows multiple episodes across a season; exact counts may be confirmed per season guide,.

• Celebrity Traitors (special celebrity edition variants): This version usually runs fewer episodes than the civilian Traitors, with recent reporting noting nine episodes in a season, rather than twelve,,.

If you can specify which version (American The Traitors, British The Traitors, or Celebrity Traitors) and which season or year you’re interested in, I can give you the precise episode count for that specific run.
