Presented by Cracking The Cryptic, YouTube’s most popular Sudoku channel, comes a new game featuring one of the most popular puzzle types: Thermo Sudoku. How does Thermo Sudoku work? Well each sudoku grid contains thermometer shapes (often drawn to create themes) and digits on thermometers must increase as one moves further from the bulb end. The interactions between the thermometers leads to new logical ideas and patterns that completely refreshes the standard sudoku solving experience. As with their other games (‘Classic Sudoku’, ‘Sandwich Sudoku’ and ‘Chess Sudoku’), Simon Anthony and Mark Goodliffe (the hosts of Cracking The Cryptic) have personally crafted the hints for the puzzles. So you know that every puzzle has been play-tested by a human being to ensure that the sudoku is interesting and fun to solve. In Cracking The Cryptic’s games, players start with zero stars and earn stars by solving puzzles. The more puzzles you solve, the more stars you earn and the more puzzles you get to play. Only the most dedicated (and cleverest) sudoku players will finish all the puzzles. Of course the difficulty is carefully calibrated to ensure lots of puzzles at every level (from easy through to extreme). Anyone familiar with their YouTube channel will know that Simon and Mark take pride in teaching viewers to be better solvers and, in these games, they always craft the puzzles with the mindset of trying to help solvers improve their skills. Mark and Simon have both represented the UK many times at the World Sudoku Championship and you can find more of their puzzles (and lots of others) on the internet’s biggest sudoku channel Cracking The Cryptic. Features: 100 beautiful puzzles Hints crafted by Simon and Mark!}

Like all good mobile games, this costs $5 and has no ads. I bought this game because I was getting bored of standard Sudoku puzzles due to them being too easy: I've struggled more with four star thermo puzzles than "very hard" standard puzzles, and in general I've really enjoyed the puzzles in this game. They're handcrafted to showcase many interesting things the themometer mechanic can do.

I have enjoyed. all of CTC's sudoku apps. I have each one several times and learn new stuff every time.

Touch controls work somewhat randomly on a Sony Xperia 10 V. Sometimes not registering, sometimes selects wrong cell

2 stars because at the very least it works. But overall the UI/UX is awful. Maybe I'm spoiled since I've come from other sudoku apps (regular and killer sudoku), but I simply think there's a lot that could be done here to make it better.

It's good for a while, but eventually you will run into puzzles that legitimately do not have unique solutions. And then when you're forced to check the hints to proceed, they will give a hint that isn't actually true. I can't recommend it.

Well, I had a much better time with this pack than with the chess sudoku one. There were only a few puzzles I got stuck on, but two of them were because they seemed to require you to see like a dozen moves ahead to see conflict. There was one time where there was a typo in a hint (mixing up row and colum in the clue).

Some puzzles are not playable because the thermos are not completly visible. I contacted the developer, but he does't respond at all.

Excellent app let down by the latest update where it no longer respects my device's orientation and opens upside down
