CineLinkr, PixelLinkr, and Little Worlds are in the DLE Directory now. I opened all three today and left them unfinished. I wanted to know which one I would come back to tomorrow.
CineLinkr is sixteen movies and four mistakes

I opened CineLinkr and did not press submit. The page was already on today’s board: sixteen film titles, four empty lives, and a note that a new puzzle arrives at midnight. You pick four that belong together. I left every tile ungrouped.
What I like, and this is taste, is that it is the grouping loop I already know, except the tiles are movies instead of words. I would open this when I want to spend a day on films, not vocabulary. Past days sit in an archive if you want them later.
PixelLinkr is the same loop with games

I left PixelLinkr unsubmitted too. Same dated board, same four mistakes, same archive. The tiles are game titles. It is not a different rule set. I would take this when I know games better than I know movies, and skip it when I do not.
Little Worlds lets you sit with a pool

I opened Little Worlds on Tidewinks and left the pieces in the tray. Daily was on, Easy was on, and the pool was empty. You place a few habitat pieces so every wish on the side is true, then you check. There is no timer. Belonglet is the other world: found things that have to go back to a neighbor.
The page said one daily solve, in either world and at any difficulty, keeps the streak. Practice is sitting there if you want more. I would come back for the dated board, not the extra practice.
Which of these should you try first?
If I only had time for one game tonight, I would take CineLinkr, because one board and four mistakes makes the day feel finished. I would take PixelLinkr when the titles I recognize are games. I would take Little Worlds when I want something I can leave sitting without a mistake counter. All three play in a browser without an account.
FAQ
Are all three games updated daily?
Yes. CineLinkr and PixelLinkr each showed a dated board and said a new puzzle arrives at midnight. Little Worlds labels Daily against Practice and says one puzzle keeps your streak.
Do I need an account?
No. I opened all three while signed out.
Is CineLinkr the same as Connections?
It uses the same grouping idea: sixteen items, four hidden groups, four mistakes. The tiles are movie titles, and it is a separate site.
Is PixelLinkr the same as CineLinkr?
The rules match. CineLinkr uses movies. PixelLinkr uses video games.
Conclusion
I left CineLinkr ungrouped, PixelLinkr ungrouped, and Little Worlds unplaced. Tomorrow I will pick one and actually finish it. If you want a daily that is movies, games, or a quiet pool of wishes, these three cover that ground.
