> Would it be a whole lot of fun to complete the game in one guess?

I would say yes. It would feel great, like you are outsmarting the game. Kind of like when you discover a good build in an RPG that helps you get ahead - even though it's often intended by the designer, you feel like you pulled a fast one on the game and it feels awesome.

If you look at it instead like a 1D version of a crossword puzzle, then it's not skipping to the end so much as just filling out one of the other words.

I see it as a UI limitation that you can't fill it in (how would you show it?). But it's fine as is, I'll just use it to help me solve the adjacent ones.

Except the games isn't linear. The goal is to answer all of the clues without getting any wrong. Answering one clue doesn't do that.

Isn't the goal to get the final answer? I think it should be allowed. Similar to not using all the available attempts at wordle or finding a secret passage to the end in a videogame.

The instructions say one can solve any clue, and I could take that to mean any bracketed phrase. If they say "highlighted clue" it may help.
