I used to play this game and it was hella fun buy when i reinstalled it i keep having to register every time i open the app and you have to be connected to thr net or else it'll be an error. Please update that part.

Couldnt get pass the registration screen i put my name ,Here,etc. It keeps putting Error. Rating for me stays at one star until it works.

Should've said registration was required. 🤦‍♂️ Not cool. None of the other games of this kind that I tried, have such requirement. If it was optional, that would be fine. If it's mandatory, then it should be specified in the main description, yet it isn't even inthedetailed description (2020 Jul 30). Uninstalling 🙁

It's pretty neat, but the click-drag callibration is off by almost an inch on the Samsung S8+, likely due to the longer screen. I could only play it for a little bit before it got too frustrating to continue. But this game otherwise seemed like a match made in heaven for me. If the bug is fixed, I'll likely redownload and enjoy it.

This is wonderful! I was looking for an easy puzzle game as a stress reliever. The initial puzzles are fun, but ConcentricHex is surprisingly easy to play, quietly challenging and immensely satisfying. And no ads!

Can't get past registration screen. Remember when you didnt have to connect to the internet to play a single player game?

very fun game, I play concentric almost exclusivley now and ranked 5th overall. my one issue is that the 1st and 2nd positions are held by Tim and TimDerBoZZ who both have 1,000,000 points, in comparison 3rd place only has 20,000. as they both have tim in their names and scores that are 50 times larger than the next i am guessing there might be some cheating. It does take some of the fun out of the game seeing as i would need 983,000 more points to even consider trying to get a top spot.

Have played this game regularly for a year now and really love it. It's very relaxing, and optically beautiful. Thanks to the designers!

perfect app for puzzles i feel. no ads, lots of free content, microtransactions are quite fair in my opinion. A true specimen of free puzzle game perfection.

Excellent game to play and relax with, though there was a major bug that guy me just today. I booted the game up and all my progress was gone. Made it past level 30, too. =/

This is a really fun app. I rate it 4 stars just because, as far as the controls go, there's an odd disparity between where I put my finger and what piece is picked up (I don't know how else to describe it), but other than this quirk, it's a lot of fun! I also wish there was a way to see your solution to the puzzle after you've completed it and came back to the puzzle, or like a gallery or something.

I saw that some people were having trouble with the puzzles, so I've written a description for how to play each one. FitIt: Align the blocks or lines to fit into the given shape. NuerOn/Off: Turn the tiles so that they either all light up, or turn off. Concentric: Place the blocks so that their edges match color to make them disappear, try to set them to cascade color matching, and keep the board clear. I thoroughly enjoy this app, the games are really fun and easy to get sucked into.

My one complaint is there's no explanation of how Concentric works. I have tried to see patterns but I still don't get how to play it. Other than that, cool game

I really like this puzzle game and I like that I can earn hints. I don't like not having control over the hint I get . I would buy hints if I could choose which piece to reveal . Make an update that allows choices and I will totally spend money. Hint, hint, you can make more money if you give control. P.S. I love the black background.

I'm impressed of the amount of all the possible combination of pieces. Simple idea yielding a ton of puzzles. Levels are replayable as sometimes you manage to complete the puzzle for sheer luck and no logic whatsoever. Different puzzles and difficulties for different tastes. Personally, I despise neurOff. All in all, a good puzzle to kill time

Spend the last year completely all of the puzzles. Great game to play when sitting on a 30mins train.

Won't load past registration - after getting addicted to this on my boyfriend's phone, I tried to download it on mine. It gives me an error at the screen that asks me to register, and does not give an option to to play without it. Haven't been able to open it once.

If you have boyfriend/girlfriend, homework, cat/dog or anything important to do, you will forget about it. This game is so good.

Turns out you have to be connected to the internet just to register your name. Now that I've played the game, it's a lot of fun!

Fun game but I got a new phone so I tried to switch my data over with the exportID thing and it's broken or something. the exportID I was given was "/>< b >W" without the spaces before and after the "b" so it didn't work or something and I lost all my data a little upset but not the end of the world. This will just be the 3rd time I've had to restart from the begining which sucks

Nice game, I particularly like the neurOn puzzles. However, the designers don't really understand what makes the puzzles easy or difficult, assuming that naive complexity automatically makes puzzles harder. This is almost directly opposite the case in the neurOn and neurOff puzzles, like a cipher with more text to work with.

This is a great game to make you think a bit while still being very relaxing. There is a ton of content here between the different game modes. I have been playing it on and off over the past 2 years or so and still feel that there is a lot more available for me. The design is simple and effective! Definitely worth a download! Also, free with no ads!!

Before one installs and for the staff to know... This game did train my brain lots but when I started to play it again many months ago and today it didn't load except for just a dark grey screen. I think this game may be outdated and may not work if one trys to install it but it helped my brain get smarter. It was also very hard/tricky past the easy and relax modes and to few hints.
