Customer Reviews

SSuggestion for developers (in case they read these reviews)

I have enjoyed this app for a few years now mainly because it closely resembles playing it with an actual paper and pencil. I’ve noticed there have been some nifty interface changes, and other subtle changes - one in particular that I wish would be removed is the “greying out” of numbers once they have been used up (or “found”) in all of the 3x3 sub-grids. This takes away from the aforementioned “paper-pencil” like experience, but most importantly, I am unable to remove that number from the “tiny” notes when I’ve previously entered it as a possible candidate - does that make sense? :-). I hope it does to whoever is reading it on the developer side. Don’t grey them out at all! I liked it better that way.

Love the app and I've been using it for years

I really appreciate all the recent effort put into the app. However, I would be grateful if the fading numbers could be turned off in the settings. While I do understand how people utilize this feature of the app by keeping track of which numbers are completed in the puzzle, I find that it takes away from the challenge. It would be a shame to take in away entirely since it seems that many enjoy this feature, but a method to toggle it on or off would be very nice. Thanks❤️

I miss TicBits

Nothing specific, but it seemed to work better before the last major update.
However, maybe a new set of eyes will find a way to give an alternative entry method, i.e. pick a number, then drop that number into every square you touch until you pick a new number, change entry method or enter “notes” mode. I’ve seen other companies versions of this game that have this. It makes data entry much faster when you don’t need to touch a number for EVERY entry.
