Killer Sudoku Varies with device

I've bought a number of the Cracking The Cryptic apps, not least because it's a way of supporting the channel when the Patreon content seems beyond me. This is the best of the ones I've tried, since the variety of constructors have come up with clever and interesting patterns. The difficulty of puzzles seems to vary strangely (am only half way through), and the star system is clunky. I tried the hints once, and they got me back on track. Maybe I can get to the end! (Or not.)

Great puzzles with very informative step by step hints, very worthy purchase. Only issue is it takes up a lot of battery and gets really hot when running. Please make it more efficient if possible, can't imagine why it would be so computationally intensive especially if most of the time it's just waiting for input.

It's hard. I'm not sure if it's too hard; the people getting this are likely to be more advanced players....but it's still very hard. Having watching a ton of CTC I feel I have a slight advantage, but once again, it's HARD! That does mean there's likely great value in this - the 5th puzzle took me an hour and 20 minutes. Point of for the immediate end screen. I want to see what I've just completed.

Puzzles are fine so far but the app drains battery (15% in the last half hour) and makes my oneplus phone get hotter than it ever has been. UPDATED to 1-star. Had to get a refund. I could smell the overheating electronics in my phone from using this app. This was on a high-quality OnePlus phone that has never had a similar problem with any other app/game. Can play some other killer sudoku apps for hours with no heat or battery issues.

A thoroughly enjoyable puzzle that will be enjoyed by anyone that likes maths based puzzles. Very user friendly software to edit, colour, undo the grid. Like all the apps from the cracking the cryptic group this too is fantastic.

Even the supposedly easiest puzzles are way harder than the easiest puzzles in the other CTC apps and in this app the hints are even worse than in the other apps. If you get stuck, forget looking at the hints to help you out. Half the time they mention a wrong row or column number and most of the time there are steps in the logic that aren't easy to see that are completely skipped in the hints. All of the other apps are nice but I can't recommend this one for anyone who's new to killer sudoku.
