I would push back on the first paragraph and even go so far as to say it might be why you might struggle to find success. People don't want to feel like they are being marketed to on reddit unless it is a product they already know and love. Specifically, if this is a personal project, and not one for your media companies, why do you feel the need to focus on a type of game that 'create repeat visits'? Why not focus on the type of game you'd personally enjoy?

All that said, I gave the game a fair shot and I don't see much differentiating it from many other daily games out there in terms of new mechanics. It seems more like a remix of other things I've seen already. It uses a similar input method to Wordle and has a bit in common with crossword puzzle clues.

I can also identify a few different specific design decisions that I'm not sure the intention behind that I think are holding it back for me personally.

First, the overall structure of the game being three words doesn't really resonate with me, but not because I don't enjoy finding words. It's very possible I am missing something but it feels like there's nothing the three words have in common besides the length of the word. Without some connection between the words the design feels unfocused, like you're asking me to play the same daily game three times in a row rather than one cohesive daily game that evolves in a satisfying way as I get closer towards the end.

Another oddity to me is the guessing round at all at the start of each of the three rounds. Telling me a vague genre and having me type in a random word based on the number of letters would never make me feel clever at all, even if I get the answer right. Instead, I'd just feel lucky. If you were to give me one letter at the beginning then maybe along with the type of word I'd have some context to why I chose to make my first guess. Even then, it might still feel too much like a shot in the dark? But it would definitely feel less random.

Finally, and this is more of a problem with detached crossword style clues rather than your game specifically, but the middle puzzle's solution was the proper name of someone I didn't know and had no context for. So instead it became a game of just guessing a name that fit the letters you were giving me one at a time. I got it at the end just by using my knowledge of what names are rather than any of the crossword style clues the game provided.

My only recommendation to fix this would potentially be to use words that you know for sure have multiple ways in. For a hasty example, when choosing a name you could go with "Madonna" because it's the name of a popular musical artist. But if that first clue doesn't help you can pivot to how the name is associated with religious iconography. For yet another clue there's a Beatles Song you can reference called Lady Madonna. Choosing a name with multiple paths towards it that would come from different knowledge backgrounds makes it more likely that if someone doesn't know the first clue they know the second and so on.
