Previous comment I made a few months ago for a similar question:

Check out Griddlers.net for tons of free puzzles on desktop. They also have a subscription option that allows you to solve puzzles offline and has a few other features that help make solving easier (and it helps to keep the site running).

Costs aren’t bad. $5 for 1 month, $25 for 6 months, and $40 for a year. They also offer family plans and senior/student discounts.

Also, if you’ve been a subscriber and something happens that you can’t afford it anymore, this is the type of company that if you email them, will give you extra time for free.

I have no official connection to this site. I’ve just been a loyal customer for over 15 years.

Tents and Trees

Cubistry

Two Dots

Alchemy

Rusty Lake series 

Flow

I Love Hue (and the 2nd one)

I can't remember the names, but there was a fun anagram puzzle app and one with cyphers that were fun. 

I like nonograms :)

I like Einstein Riddle. They're little picture-based logic puzzles. No ads, lots of levels, varying levels of difficulty.

Hi. I sent 2 unique puzzle game. Check messages

If you like Sudoku and looking for something more challenging, might I suggest dailykillersudoku.com it's a website but it works great on mobile. I absolutely love this website, it's just one guy who makes them and hosts the website.

Killer sudokus are like regular sudokus but has no number, instead it has these groups of 2 or more boxes that add up to a number. You can slove them by combining maths and sudoku strats. On the website you'll find more explanations if it sounds confusing.

Would you like to try my first android game. It was published a week ago. It is based on the Mastermind board game with some fun twists.

https://play.google.com/store/apps/details?id=com.jaymaze.mysterymatrix

Try my game Runes: Puzzle

Try mine, Mummy Maze: Pocket Edition

Shameless plug 😉 https://frankgoyens.itch.io/dangerzones

Mobile friendly, no download, no ads or mtx

If you like block puzzles you can check out my game: Brick Busterrr

It's a block puzzle game with some rougelite elements, item usage, HP management, and unlockable tools! :)

Discussion: I've really liked ones by Conceptis Puzzles lately. On android at least they have free to play ones without ads including weekly bonus puzzles (though it's money to buy additional packs). The pic-a-pix one is a neat play on suduku.

Discussion: please us the "not seeking solutions" flair so all our comments don't get removed for not having spoilers. As for my recommendations, Simon tanthams puzzle collection, I think it's called. It will entertain you for hours. Also sugar game by bart bonte

Discussion: Agent A: a puzzle in disguise. Best puzzle game I ever played.

Also "the last door" , it's a pixelated point and click adventure. The story is quite well written.

"The silent age" : another point and click adventure. Storyline involving time travel and puzzles are good enough.

The room series :as mentioned by someone else in the comments. There are quality puzzles.

The adventure escape series : They have a lot of different games on PlayStore and the quality of game varies with each one of them.

" Layton brothers mystery room" : Played it long time back. Not sure if it's still there on playstore but it was detective mystery puzzle game.

"No bodies" : mentioned by someone else in the comments. Definitely recommended. A very fresh idea.

"The frostrune" : another game I have heard a lot about but never played. You can give it a shot.

The cube escape series(rusty lake series): have played few games from this series. Good enough.

The Guides Axiom is pretty good. One of those ones that doesn't really tell you what to do, it just lets you work it out.

If OP hasn't played Baba is You, this is the correct answer. One of the best puzzle games of the last decade. I didn't even know it was on mobile until yesterday.

Never played a game that made me feel so brilliant and then so stupid all mixed together. It is viciously hard in later levels.

Mind bending solutions!

Didn't know it was on mobile thanks!

Discussion: I run these:

Discussion: Logic Masters Germany is mostly variant sudokus, but there are a good deal of other puzzle types there, too.

Discussion: Simon Tatham's Portable Puzzle Collection

Reposted because the automod does not appear to know the difference between a puzzle post and a question post.

Discussion:

https://puzzlepass.io/en/ has daily puzzles.

https://krazydad.com/ has a large database of online puzzles as well as printable puzzles.

https://www.printable-puzzles.com/ has, uh, printable puzzles.

https://www.puzzmo.com/today/ has daily puzzles.

https://puzz.link/db/ may be the granddaddy puzzle site.

Discussion: Are you familiar with logic-masters.de? In my opinion this is where the worlds greatest puzzle setters provide puzzles on a daily basis. They have a great portal to search for puzzles, I recommend trying some of the nicer ones in each difficulty (puzzles have a ‘niceness’ rating and difficulty rating). Try to find the difficulty that suits you and get puzzling. Most puzzles provide a link to solve online in one of the tools

Discussion: you may like the Professor Layton series of games.

Or if you prefer more sudoku but bored of Vanilla, try the Cracking the Cryptic mobile apps. Miracle Sudoku is also a fun one.

Or, if you prefer the logic puzzles as themselves, search for:

Nurikabe
Hashi
Battleship
Star puzzle
Tents and trees
Heyawake
Thermometers

And quite a few more. There are websites devoted to puzzles like these, too. Most for free.

Discussion: montague island series

I enjoyed Journal29. Available on Amazon.

You might enjoy r/ElementSynergyPuzzle**/**! It's a Sudoku inspired game that you can play directly on Reddit for free, with daily challenges of varying difficulties. If you enjoy logic based puzzles with a twist, it could be a great addition to your rotation

wowzen in airplane mode to avoid excessive ads, letter-based vs definition based crosswords

gubbins, kinda like whacky scrabble?

Nonograms - make pictures using numbers on the sides that intersect

Einstein puzzles - assign objects and details in a grid

Every day I play Wordle, Spelling Bee, Connections, Strands, Swiftle, Bandle, Queens, Frogs, and Waffle.

I used to play NYT games every single day with my coworkers, a nice 10min of competition and a quick brain break. But then our agency blocked all the games and we cant have phones inside. So I dont get to play nearly as much anymore, I always forget by thr time I get home. But wordle, connections, spelling bee, were all my favorite. Outside that I love to play scategories or taboo on game nights with friends

I have Apple Arcade as part of my bundle, and really like Grindstone and Stitch. Especially since they’re ad free

I play the NYT games every day, and I also like cross logic puzzles

As I started reading, I was all ready to say, "I Love Hue!!!" because that is the first one that came to mind, and I really enjoy it. I haven't really gotten into "I Love Hue Too" as much though. I'm not sure why that is.

The other app style that came to mind for puzzles that aren't puzzles, but where you end up with an image in the end is/are PathPix, especially PathPix Max. I have spent hours working through all of the images and artworks. I highly recommend the Max, as it has 114 giant puzzles, with over a million squares total, so you get a lot of bang for your buck.

I have a couple logic-based games that I really love, that I think are sort of puzzle-like:

Pathpix has you connect pairs of colored numbers to create a picture. I like the ones by KpixGames.

Nonograms gives you information about how many squares are shaded (vs empty) in each row and column of a grid to create a picture. Nonograms 999 is my favorite.

Happy Color. It's a color by number app that has lots of different art styles and is very satisfying to play. To me, it gives a similar fulfillment as puzzles because you're meticulously completing something bit by bit. Free to play, but you can pay a few bucks to remove the ads.

Just wanted to add that there is an I Love Hue Too if you didn’t know! It’s more geometrical so has a bit more of a real puzzle vibe

It’s so addicting, I used to play it before bed but I think I pavlov’ed myself to fall asleep every time I play it now lol

I love Puzzle Page (I am a subscriber). It's logic puzzles and things of that nature, but it does scratch that jigsaw itch. And sometimes they have events where you are completing puzzles to get the pieces to do a jigsaw in-app. Probably my favorite phone app ever.

Hi! Are you into scifi at all? I am working on a daily sci-fi crossword app.

It's now on testing (Google play store). If you're interested I'd be happy to add you to the beta testers!

Do all the Exit escape room boxes. They are $10-15 each and very high quality across the board, although some are too challenging. They also have amazing advent calendar adventures.

Penny Press has some books that skew more toward math and logic solving, like their Premium Variety Puzzles and Tournament Variety Puzzles. You'll still get traditional logics, Sudoku, Word Seeks, etc, but you'll also get some cool tougher deduction puzzles.

Also, for tougher Sudoku ones that are heavy on deduction, check out anything Thomas Snyder puts out.
