- Jeopardy!. One of the two locks on the board, and the entry for the trivia theme.
- Wheel of Fortune. The other lock, and fits the non-trivia knowledge category.
- Takeshi's Castle. I'd like at least one non-US entry, and this fits the physical category.
- To Tell The Truth. The panel show was a staple of earlier game shows, and with four separate runs, three of which were successful, this gets my nod.
