The non-spelling format was used the week of 4/8-4/12/1985 when Amy Albani Schultz won some of her nine Sprint rounds. So this is at most the third week of the Spelling format. This could be a Monday episode(though it's airing on a Tuesday because A-Team etc. was said to air "tonight" in the NBC voiceover in the end credits, maybe they're delayed a day because of a special report preempting a show recently) because in the straddled maingames format, when a game straddled Friday into Monday, the board opened up at the beginning and didn't show the previous words played, like it would on a Tue-Friday episode. Of course this show had technical problems from time to time..... Given the sprint champ had previously won four games, and the total was not a multiple of 500, this is at least the second week of the Spelling format.
These April-August 1985 episodes where you had to spell were skipped by USA Network in 1993. They skipped from April to September 2. The ending is the intro to that day's 𝘚𝘶𝘱𝘦𝘳 𝘗𝘢𝘴𝘴𝘸𝘰𝘳𝘥 with Patricia Klous & Orson Bean.
