I seriously don't get the idea behind daily challenges unless you want to keep users hooked to extract some value from them, but that doesn't seem to be the case here, as there are no ads.
That's fine. So these kind of games aren't for you, then. Remember crosswords in newspapers? Yeah, think of it like that. You don't get hooked until you cannot let go, you get a limited chunk served each day. Same with Wordle.
I remember buying a magazine full of crosswords and similar puzzles when I was in the mood.
And when there were sites with unlimited Wordle, I played a few in a row.
On the internet, unlike with newspapers, you're not limited to how many levels/games you can make per day. Making it once per day doesn't make any sense whatsoever. It's condescending to the users and feels like a power trip.
> It's condescending to the users and feels like a power trip.
condescending (adjective): having or showing an attitude of patronizing superiority.
I don't really see how a once-a-day puzzle is condescending, unless it's a "You can't be trusted to regulate yourself so I'll do it for you" type thing. Adding a dictionary definition like above, however, probably is condescending :)
But I like the one-a-day format because, as other comments have said, you can spend an entire day with just one puzzle feeling important (relative to things that are important).
You can freely make levels and browse other people's levels. The complaining about power trips seems as uncharitable a perspective as you could possibly conceive of, not to mention a bit theatric.

Ironically, that's what I initially liked about the daily puzzles like Wordle: they forcibly prevented you from sinking too much time into them. It was sort of like, "hey here's something cool, and I'm going to make sure it's a positive addition to your life by preventing you from succumbing to your own addictive impulses". You could call that condescending or infantilizing, but to me it's just part of the look and feel of a thing. Especially if the author isn't charging money, they get to use whatever tools are at their disposal to craft the users' experience of it. Wordle Over And Over Again is a different game than Wordle Once Daily. (And WOAOA done properly would probably have a progression of difficulties, or themes, or something, whereas WOD makes more sense with pure randomness.)
I assume that "all the different levels" might not exist yet. The author is probably creating them a bit in advance, and will keep going as long as they're motivated. Having a regular schedule for new releases helps, and doing it daily seems as sensible as any other schedule.
Just show all the different levels at once.
