RNGdle is in the DLE Directory now. I sat on the play page long enough to see what the day asks for, then I stopped. If I press Generate, that is the roll I keep until tomorrow. I was not going to spend it on a review.
You get one number, and then you read it

The page is mostly empty until you roll. Six question marks sit over a line that says you get one number a day, and a Generate button under that. I did not click it. The draw runs from 0 to 1,000,000. Then the site looks at the number for primes, palindromes, repeating digits, meme numbers, and other patterns, and it hands you badges for what it finds.
That is the whole loop. There is no shared answer to hunt. Your number is yours, and the interesting part is whether it is dull or strange. The page also shows today’s best roll and a leaderboard if you want to see what other people landed. Signing in is optional; it is there if you want the roll saved. I would come back for the one-shot, not because I think I can out-think a random draw.
Which of these should you try first?
Start with RNGdle if you want a daily that is over in a minute and still feels like you used the day. Skip it if you want a puzzle you can reason through. This one is luck, and I mean that as a description, not a complaint.
FAQ
Is RNGdle updated every day?
Yes. You get one roll per day. The next one waits until tomorrow.
Do I need an account?
No. The Generate button is there while you are signed out. An account is only useful if you want the roll saved and shown on the leaderboard.
Does everyone get the same number?
No. Each player rolls their own number. The daily part is the one-roll limit, not a shared answer.
What are the badges for?
They mark properties on the number: primes, palindromes, repeating digits, meme numbers, and other patterns the site recognizes. Rarer badges are worth more.
Conclusion
I left RNGdle unrolled on purpose. Tomorrow I will press the button, look at whatever comes up, and that will be enough for the day. If you want a daily that does not ask you to solve anything, this is the one I would open.
