Thermo Sudoku

These puzzles are an amazing variation to sudoku! The rule is so simple, yet it adds so much fun complexity to the game. The user interface is pretty good now that I’m getting the hang of it, but I would give this 5 stars based on the puzzles alone. It’s nice to feel excited about solving sudoku again.

The UX for this app is just amazing. I'm not sure that there is a better implementation of a sudoku board in any app of website. It's so intuitive and great. The devs should put the same functionality into the Website!

I’m really impressed by this app. More difficult puzzles are unlocked by beating easier ones (which I guess could be frustrating if you’re really good, but I’m not! So it’s fine). The app will alert you of illegal placements, so you don’t waste too much time, and you have real variety in how you can mark each square - not only with pencil marks of possible numbers, but with a different style pencil mark for set pairs and triplets but also with x’s for focusing on single digits (and where they can’t be placed) and highlighter colors to identify key squares. Really nice!

Not your normal sudoku here, this one turns up the heat with thermometer logic. Excellent hand crafted puzzles and an easy to use and aesthetically pleasing interface!

Paying the premium for these high quality puzzles was totally worth it. Looks great, plays great, performs great, and the functionality of the puzzles and notation is superb!

The controls are so bad as to make it almost unplayable. Why not use the same number pad as Cracking the Crypto? If you fix this, i’ll change my rating to five stars.

Great app, but sometimes when exiting and re-entering the app while solving the puzzle, the timer jumps, sometimes hundred of minutes at a time. I didn’t have this error on the Classic or Chess sudoku app.

Still waiting for the last 20 puzzles that were promised. Been at 80 for a while

The app description says it will be enhanced to 100 puzzles within a year of introduction. It has now been over 20 months and we are still waiting.

Love Cracking the Cryptic youtube channel so i had to get 1 of their apps. These puzzles are a lot of fun. My only issue is that there is 1 weird bug that can be quite annoying. Whenever you leave the app and load it back up, there is a wrong number put into box where you left off. Happens almost every time. Normally if this happens without resetting the app, you can just hit the undo button.
