★★★★★ Update 10/9/26: I paid the $13 to go ad-free, but they just moved the ads to the bottom of the screen and are now interrupting gameplay with ads for their new game.
★★★★★ Full screen ads on puzzle select, DURING puzzle-solving, and on puzzle clear, Bottom banner ads on puzzle-solving, thank god there are no ads in this review 😄.
★★★★★ The ads every tie i start and end a game and every few minutes during the game is just insane and no im not paying 25 or 20 bucks.

★★★★★ stop the ad wall for fill candidates and the paywall to complete it fully
★★★★★ this app is a blatant money grab designed to harvest and sell every iota of information about you that can be scraped from your phone.
★★★★★ and removing them isn't a 1 time purchase, it is a subscription.

★★★★★ Just lost a completed, error-free hard game!
★★★★★ Once the ad is over, let's say I now forget to hit the undo button (due to the break in thought flow caused by the ad) and stick the proper number in, now my pencil marks got affected and bam, another "error" to a…
★★★★★ horrible ui, and buggy at times.
6 of the 1 and 2 star reviews.
★★★★★ Price for premium mode are already too exaggerated considering the high amount of ads in the game, it was great to play a limited version of the game offline with - STILL ads (logicwiz specific) - no hints/skips - no…
★★★★★ they're not limited to between puzzles, you will get multiple intrusive ads during a puzzle that require waiting and multiple "X" presses and sometimes getting redirected out of the app.
★★★★★ Too much locked behind premium

★★★★★ Just lost a completed, error-free hard game!
★★★★★ I've deleted the app, and will reinstall, but I'll ditch it altogether if the persistent ads (Whiteout Survival) that don't have a X where you can Close them don't stop.
★★★★★ Update: Paid to get rid of the ads and everything was great until I got a new phone and there is no way to restore the lifetime membership I paid for.
5 of the 1 and 2 star reviews.
★★★★★ There was nothing wrong with the classic keypad yet you just had to put that new garbage keypad on by default.
★★★★★ The title of Variants is wrong.
★★★★★ The Ads are insane, You can't close many of them, they use fake X close buttons and just you get stuck in a redirect loop for basically porn or cheap knockoff products.
3 of the 1 and 2 star reviews.
★★★★★ The puzzles are fun, but I'm uninstalling the app because it runs terribly, and seems to slow down my entire phone.
★★★★★ I do notice this game drains the battery FAST!
★★★★★ the game runs very slow and ads after almost every puzzle solved.
62 of the 4 and 5 star reviews.
★★★★★ The unique "thermic" twist adds a level of fun by helping solve the most difficult puzzles.
★★★★★ I love the event ones, pretty fun to kill an hour or two with a master rated puzzle from there
★★★★★ Fun game that makes you think .
30 of the 4 and 5 star reviews.
★★★★★ Love playing Ad Free but the ads were not horrible to start with.
★★★★★ Update after a few years: I bought the lifetime premium version because i spend so much time on the app, i feel it is worth it.
★★★★★ I don't pay money for games on my phone, but I ended up dropping $20 for this one and it was worth every penny.
26 of the 4 and 5 star reviews.
★★★★★ great ui design and enjoyable game modes!
★★★★★ Ads are always short, UI clean, offline play, devs active.
★★★★★ New to this version of sudoku, but tons of variations to keep it fresh, and the interface works very well so far.
20 of the 4 and 5 star reviews.
★★★★★ Customisable settings to make the game as hard or easy as you want and great help content on solution methods.
★★★★★ It is really well made and user friendly.
★★★★★ good range of levels from easy to master, and master is actually challenging not like some other apps where a top level is easily doable in a few minutes.

★★★★★ There are helpful tools to use; the hints are making sense; new puzzles are rolling out regularly; and the game modes are fun to explore.

Plenty of challenge, if you think you're already a great Sudoku player.
super friendly and helpful developers, great app, awesome choice and variety. I love it
Sudoku is one of my favorite puzzle games. The unique "thermic" twist adds a level of fun by helping solve the most difficult puzzles. I really like it.
