About this app
Developer Description
Handcrafted Thermo Sudoku puzzles by YouTube's most popular Sudoku channel!
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.

Awesome app. You have to like the thermo sudoku varient, but like all of the other apps by this publisher all of the puzzles are handcrafted and you have to complete some to unlock more puzzles which means that you have both a sense of progress and a fun steady increasing difficulty throughout the progression with the app.

Enjoying it, but when I get stumped, the hints are problematic more often than I would like. They refer to patterns I don't know being a novice (such as x-wing?). Also a couple of typos and logical failures which really should have been caught. Eg, a puzzle 38 hint references a column 9 thermo rows 1/2/4, when it only goes to 3, and the numbers given don't fit the 5/8 pair in the box below, which by the starting numbers and the middle thermo can only be there. I could be wrong, but it seems off.

I would like to give this game more stars but I can't in all fairness. It uses Unity, a 3D games engine, for a non-3D game; that's over kill! It uses way too much battery. A 10 min game on my old (slow) tablet took 10% of battery life and lagged. Also the games doesn't sync across devices. Which I expected, given you are trying to get the fastest time for a limited number of boards. But misgivings aside I love the game, will probably buy others from the same stable, and yes, I do recommend it.

The game itself is great, mostly(dark background and dark numbers mean it's sometimes hard to process). Very interesting puzzles. But there's not enough puzzles. It's been over 4 months since they added some puzzles, and there is a promise of 100 total puzzles by May. I will change my rating when the promised puzzles are released

Excellent sudoku puzzle which is let down by probably the worst UI that I have experienced on Android. The app opens upside-down and completely ignores my device's rotation settings: auto rotate is off but it still rotates the screen if I move the device slightly off straight. It's the same for all of the CTC sudoku apps.
