Season 30 (2013-2014)
- The 2013-present set was introduced starting with this season.
- The sliding doors behind Alex's podium were removed from the set, so the ramp behind the game board was added.
- There are LED borders on the game board, on top of that, there are three LED strips and rectangular LED posts on the sides, which look just like the ones used on its sister show Wheel of Fortune.
- Alex's podium consisted of LED strips to match the game board, and the Jeopardy! logo was added to his podium.
- The piano key LEDs were removed from the set, so the contestant side was raised to create a single floor.
- The contestant podiums resemble the 2006 models while retaining the sideways monitors.
- The large monitor between Alex and the contestants was removed, so a new one with a thinner frame was mounted.
- The curtain backdrop from the previous set is retained.
- The opening credits have changed to red spheres and meandering lines as the camera pans out to reveal a CGI rendering of a globe, making the green lands on the globe appear; and the globe intro makes a comeback, albeit much different from the '80s and '90s. The Jeopardy! logo and 30th anniversary zoom out to the center of the screen from top and bottom respectively, and then the logo zooms forward, cutting to the current set through the "A" like in Seasons 27 and 28.
- The backdrop for picture clues, Daily Doubles, and split-screen closing credits on episodes with a full credit roll, changed its color to a blue starry background, appearing similar to the one used in Season 24.
