HOW SURE ARE WE
Not in any grossing chart, so this comes from ratings growth (2752 new ratings a month on average since launch): revenue grows with new ratings, more slowly for apps that collect ratings fast. Tested on 418 apps with verified revenue: typically off by about 2 times, and big earners tend to come out low. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

WHAT THEY COMPLAIN ABOUT · SHARE OF BAD REVIEWS
Too many ads73%

231 of the 1 and 2 star reviews.

★★★★★ Ads are no problem, but here they pop-up in the middle of a puzzle.
★★★★★ ads ads ads game is rigged for ads ads ads
★★★★★ Could be fun, but you can't even play a single puzzle without multiple ads.
Lost data, sync, backup6%

19 of the 1 and 2 star reviews.

★★★★★ They pop-up in the middle of your carefully thought play and make you lose focus
★★★★★ deleted out of frustration
★★★★★ After interrupting my game with 4 commercials, I lost concentration.
Price and subscription5%

15 of the 1 and 2 star reviews.

★★★★★ These ads don't give you another heart, they're just to give the developer more money.
★★★★★ Price of the ad-free version is very well hidden - when you finally find it, it is far too expensive (£11.99).
★★★★★ not the type that flash up and last 4 seconds, the type you have to watch for a bit and then press arrows and skips to get past just to get into the play store, just to back out to get back to the ad to then cancel the…
Bugs, things not working3%

9 of the 1 and 2 star reviews.

★★★★★ doesn't work, I filled in all the rows and columns so they equal the target and so does each coloured area but it isn't saying the level is complete!
★★★★★ however the amount of ads popping up is so much, I would say this is a bug.
★★★★★ Too many ads, and I feel the games been getting buggy like changing from the eraser after an ad for no reason.
Crashes and freezes2%

6 of the 1 and 2 star reviews.

★★★★★ and lately ads freeze and require me exit and reopen.
★★★★★ Crashes if you have no WiFi
★★★★★ app keeps crashing even after clearing cache and new installation
Wrong or poor results2%

6 of the 1 and 2 star reviews.

★★★★★ The reward system for this game is wrong.
★★★★★ For example, when there are multiple instances of the same number (such as 2) in a row or column, you lose one heart when you select the wrong 2, even if the sum does not exceed the row or column value.
★★★★★ When you correctly finish a column or row, the remaining (wrong) entries should automatically be removed, as they used to.
Worse after an update2%

6 of the 1 and 2 star reviews.

★★★★★ Update - uninstalled, just too many in-game ads!
★★★★★ Not sure why but this was updated to put ads every few moves.
★★★★★ Update: Easy Brain Dev team doesn't care about dark mode, and building products that are easy on the eyes - to play for longer periods of time.
Limits, credits, locked features1%

2 of the 1 and 2 star reviews.

★★★★★ I understand you have to pay bills and there are options for no-ads, but this is just overly greedy and even though I like this game, it's getting uninstalled.
★★★★★ = No Development just vehicle for adverts for unsuspecting clients who don't realise what a limited audience
WHAT THEY ASK FOR
  • of course the game needs ads to support the cost of developing and maintaining a free game. 1★, Sep 23, 2026
  • Game is great, but it would be awesome if you added a way to enlarge the text or zoom in. 4★, Aug 31, 2026
  • Go for it I can live with that, I need a hint? 1★, Jul 15, 2026
  • I wish you to know that I like the idea but I did not understand it especially when the color bars go across. 2★, Jul 12, 2026
  • very good, I play this game everyday, please add a dark mode 4★, Jun 10, 2026
  • The game needs a hardcore mode (no life) and colour blind mode. 2★, Jun 8, 2026
  • would be nice to have a way to lock it in for sure. 5★, May 30, 2026
  • My only suggestion would be to add an auto complete at the end when you've solved the puzzle and there are only extra numbers left on the board. 5★, May 26, 2026

★★★★★Oct 22, 2026

Ads are no problem, but here they pop-up in the middle of a puzzle. And not after completing a section or line. They pop-up in the middle of your carefully thought play and make you lose focus

★★★★★Oct 22, 2026

Let me start by saying I love this game. My three-star review comes as such due to the events in the game. The Haunted Mansion event that just ran was 137 or more puzzles to complete, which they give you about 2 weeks to do this, but they are also simultaneously running two more events. Both of these started after the larger event, and gave you less time to finish them each. That's like 250 puzzles. Then next week, there will just be no events. Figure out a better schedule.

★★★★★Oct 17, 2026

really enjoy play daily

★★★★★Oct 16, 2026

Great game.

★★★★★Oct 16, 2026

7 ads for one puzzle! starts off with one between puzzles, but after the first few, it goes to one after and another before. and only 20 puzzles in and mid puzzle ads occur. and they occur at most inopportune times. deleted out of frustration

★★★★★Oct 16, 2026
