Sudoku – Classic Sudoku Puzzle

My Experience with Sudoku – Classic Sudoku Puzzle

I’ve been playing Sudoku on my phone for maybe three years now. My old app started crashing every time I tried to open it last month, which drove me crazy. So I looked around and found this one. Been using it for about two weeks, mostly sitting in my recliner with my morning coffee before the house gets busy. Last Tuesday I spent a whole hour on an expert puzzle while my wife watched her shows. The app didn’t freeze once, which is more than I can say for the last one.

The puzzles feel fair. Not too easy, not impossible. I like that I can pick a difficulty that matches my mood. Some days I want something relaxing, other days I want a real challenge. The auto-check feature is nice because it catches little mistakes before I mess up the whole board. I’m not a fast player. I take my time, think things through. This app doesn’t rush me or make me feel stupid when I need a hint.

Features Worth Noting

The pencil mode is probably my favorite thing. I can jot down little notes in the squares, like possibilities I’m considering. Helps me keep track without writing on paper. The highlight duplicates option is also handy. It lights up numbers that appear more than once in a row or column, so I can spot my errors quickly. I use that all the time because my eyes aren’t what they used to be.

There are different themes and colors you can pick. I just use the default one because it’s clear and easy to read. The font size is big enough for me, which matters a lot. I’ve tried apps where the numbers were so tiny I had to squint. Not here. The statistics tab tracks how many puzzles you’ve solved and your best times. I glance at it sometimes, but I’m not competitive about it. My wife gets a kick out of comparing our scores though.

You can also input your own puzzles if you want, but I haven’t tried that yet. Seems like a lot of work. I just play the ones they give me. So far there are plenty to keep me busy.

What Needs Work

The ads are annoying. I get it, the app is free, so they have to make money somehow. But sometimes an ad pops up right when I’m in the middle of thinking. Breaks my concentration completely. On Saturday I lost my train of thought on a hard puzzle because a video ad started playing out of nowhere. I almost deleted the app right then. I understand advertising, but the timing could be better. Maybe after you finish a puzzle, not while you’re still working on it.

The leaderboard feature feels pointless to me. I’m not trying to compete with strangers. I just want to relax and keep my brain sharp. Maybe younger folks like that sort of thing, but for me it’s just clutter on the screen. I wish they’d let you hide it completely.

Also, I wish there was a way to turn off the sound effects without digging through settings. The little click noise when you tap a number gets on my nerves after a while. I figured out how to mute it eventually, but it took me longer than it should have.

Pricing

The app is free to download and play, which is great. You don’t have to pay anything to get started. But there are ads, as I mentioned. If you want to get rid of the ads, you can pay a few dollars. I haven’t done that yet. I’m still deciding if I use it enough to justify it. For now I put up with the ads because the core game works well. But if the ads get worse, I might cough up the money. My son told me it’s only a couple bucks, so it’s not a big deal. I just don’t like paying for something that used to be free with my old app.

Developer Notes

The developer, Guru Puzzle Game, seems to update the app regularly. I noticed it updated once since I downloaded it, and nothing broke, which is always a relief. Some developers mess things up with updates. The app store reviews are mostly positive, which is why I tried it in the first place. Lots of people complaining about the ads too, so at least I’m not alone in that. I appreciate that the game works without needing an internet connection. I play it in the waiting room at my doctor’s office where the signal is terrible. Works fine offline once you’ve got the puzzles loaded.

Security & Privacy

I’m careful about giving apps permission to things they don’t need. This one only asks for basic stuff like storage to save your progress. I checked the permissions before installing. No access to my contacts, no location tracking, none of that nonsense. It does show ads, which probably track some things, but I figure that’s standard these days. I haven’t noticed anything suspicious. No strange battery drain or data usage. For a retiree like me who doesn’t share much online anyway, it feels safe enough. Just be aware that free apps make money somehow, and it’s usually through ads and data. I’m fine with it as long as the game plays well.
