CBS Media Ventures’s Jeopardy! has had a string of guest hosts this year since the death of Alex Trebek in November.

The show’s ratings started out on top at 6.2 when Ken Jennings began his six-week guest hosting stint in the week ended Jan. 17. But since Jennings’ start the long-running game show has had a bumpy ride, bottoming out at a 4.8 in the week ended May 2 with Anderson Cooper hosting his second week.

Ratings have since rebounded, though, rising to a 5.2 in the week ended May 9 with CBS 60 Minutes correspondent Bill Whitaker hosting. In his second week at the podium, Whitaker held on to a 5.2. 

Buzzy Cohen, hosting the Jeopardy! Tournament of Champions, maintained a 5.1 in each Tournament week he hosted.

The most recent numbers are from the week ended June 13, which saw the long-running game show move up 4% from a 4.9 to a 5.1 with Mayim Bialik guest hosting for the second week. Bialik tied Dr. Oz for second-to-last in the previous frame.

Find out how the guest hosts (so far) stack up below. Ratings are based on live plus same day national household ratings from Nielsen Media Research. It's also important to note that ratings are affected by more than the guest host. Preemptions, awards ceremonies, and March Madness, for example, all have an impact.
