Differences by Easybrain is a popular find-the-difference game praised for its relaxing and challenging gameplay, but recent updates have led to a significant increase in intrusive ads, performance issues, and a controversial 'keys' system that forces users to play mini-games.

This 'spot the difference' game is generally enjoyed for its ability to provide mental focus and relaxation, with many users appreciating the variety of puzzles. However, recent reviews highlight a sharp decline in user experience due to an overwhelming number of ads, frequent app crashes, and a new 'keys' system that many find frustrating and poorly implemented.

Recurring themes

Ad Overload negative
Many users report a significant increase in the frequency and intrusiveness of ads, with ads appearing after every level, during gameplay, and often having sound or being difficult to close. This contradicts the developer's general 'stability improvements' claim, as ads are a major source of instability and frustration.R1R12R25R31
Performance Issues negative
Users frequently report app crashes, freezing, slow loading times, unresponsiveness, and the game causing devices to overheat and drain battery rapidly. This directly contradicts the developer's claim of 'performance and stability improvements'.R3R24R40R52
Keys System negative
Many players are frustrated by the introduction of a 'keys' system that requires them to play separate, often disliked or poorly optimized, mini-games to unlock new levels in the main game. This is seen as a tactic to force more ad views.R9R21R26R35
Gameplay Changes negative
Some users note changes to the core gameplay, such as increased difficulty, shorter time limits, or less realistic/intentional differences, which detract from the original enjoyable experience.R2R42R55R159
Relaxing & Engaging positive
Despite the issues, a core group of users still find the game relaxing, mentally stimulating, and a good way to improve focus and visual acuity.R6R7R8R11

Who it's for

This game is for individuals who enjoy 'spot the difference' puzzles and seek a mentally engaging or relaxing activity, provided they are willing to tolerate a high volume of intrusive ads and potential performance issues R6R11R18R63. It is not recommended for users who are sensitive to frequent ads, expect smooth, uninterrupted gameplay, or for parents looking for a frustration-free game for young children R55R63.

Evidence note: The recent reviews skew heavily negative, particularly regarding ads and performance, which contrasts sharply with the high lifetime rating. The developer's release notes claim 'performance and stability improvements,' but recent user feedback directly contradicts this, indicating a worsening experience in these areas.

  9. [R36] 3/5 · US Review: Challenging game
  10. [R69] 3/5 · US Get rid of those ads please: The game itself is quite fun, I enjoy the variations on “find the difference” and the different art styles are very enjoyable to look at. The reason I am giving the game three stars is that lately there is an ad banner that runs at the bottom of the screen that is loud and obnoxious, the ads have to be individually muted, and they just begin running again after about 6
  11. [R93] 3/5 · US DIFFERENTD: a little hard fun, challenging
  12. [R1] 1/5 · US Change is bad: Played this game for years. It was interesting and challenging at times. Now the adds open SHEIN during the game. Not just a pop up but actually opens the SHEIN website. It’s ridiculous, annoying and wrong. I’m deleting the game now.
  13. [R12] 4/5 · US Fun: Such a fun game but WAY TOO MANY ADS
  14. [R25] 1/5 · US The ads are horrendous: The ads are just awful. They will not close at end of add. I left android due to these types of things. To be nice. Give warnings to ads. Otherwise cool game that is compromised due to ads.
  15. [R31] 3/5 · US No & no: a lot of advertising, impossible to play... Otherwise the game would have been interesting.. deleted Hello. Thank you for your answer. I understand the concept of free applications. And I don't mind advertising, if it doesn't interfere with playing...
  16. [R9] 1/5 · US Was Fun, But…: Fun at first! I got past the first few levels but then I had to earn keys to unlock another puzzle, 1.) I’m not sure why they are “forcing” you to take breaks between Difference Puzzles like that. On top of that, the “Get More Keys” puzzles take longer to solve, mostly because it is poorly optimized and the UI is clunky at best. The “get more keys” feels like a tactic to insert mor
  17. [R21] 1/5 · US ADS: Ads take up everything I can’t even get keys! What is this nonsense?!
  18. [R26] 1/5 · US really bad: you have to get keys to play levels, but the only way to get keys is by playing a different game. you’re going to spend two or three times as long on that other game because it’s absolutely horrible, very visually cluttered, and poorly optimized. absolutely do not recommend
  19. [R35] 1/5 · US Not exactly the game I was hoping for.: They make you play some other game in order to get enough points to play the actual game you wanted.
  20. [R3] 1/5 · US Game load non existent: Game loads but doesn’t open
  21. [R24] 5/5 · US Find Differences I enjoy the most so far but none of them seem to working now!!! What is going on??P: Not happy at the moment!!🤔😳🥲
  22. [R40] 1/5 · US Won’t worked: Downloaded and it locked up. A few times.
  23. [R90] 1/5 · US App Crashes with latest update: I updated the app 3 days ago and now it won’t open. It crashes every time I try to open the app. Very disappointed as nothing is being done and bot responses to other Users complaining about the same issues.
  24. [R52] 3/5 · US Heats up phone: Beware. When using the app, your device will get hot. I’ve reached out and they claim they’re working on it. It’s been a month.
  25. [R60] 5/5 · US Overheating from recent update.: My wife and I have iPhone 13 reg and 13 mini. Since the update 1 week ago, we notice especially on her mini that the screen gets hot to the touch within the first minute of play. This only happens when playing Differences and only since the June 2025 update. Any ideas? Thank you…
  26. [R67] 4/5 · US Hard on battery life: I like the app but it uses a lot of battery
  27. [R119] 3/5 · GB Good game: Really enjoying playing this game but the problem I have is that it drains my battery so quickly and my phone gets incredibly hot! Far too many ads. Think this needs tweaking so the game is more enjoyable.
  28. [R2] 1/5 · US Rating: It has become boring because the stages are repeated and the time is not enough to solve the puzzle. · translated
  29. [R42] 3/5 · US Too hard: I played this game for a year now and it’s always been one of my favorites. My favorite was the daily challenges. They just made a change to the game so it’s almost impossible to finish ever within the time limit. They kept the same 2 minute time limit but made the pictures much more dense and doubled the amount of differences to find 😩 not happy Update, I’m actually deleting this app t
  30. [R55] 1/5 · US Umm I don’t like the app and it’s very hard: So this is a seven year old speaking (I’m turning 8 soon) I don’t like this app because there are like ads every stage and ITS TO HARD like when I do a game then I don’t know what to do because ONLY AN ATOM WOULD BE CHANGED if you are an parent who is gonna download this for you kid DONT your kid will be screaming because of ads and hardness. If you are
  31. [R159] 3/5 · GB Why are so many so small?: Why did u put like 2 of them so small that I need a hint for them can u make them a bit bigger but still I love the game it’s great thank you so much
  32. [R43] 3/5 · US Obnoxious ads: Ads for items sold by Amazon and other online retailers and ads for the Weedmaps app get you stuck in an almost endless loop and it takes multiple attempts to close the ads to go back to the game. I accept that ads are part of free play, but I’m so done with this game due to this practice.
  33. [R46] 1/5 · US Used to be better: Can’t figure out how to get past ads to play free version
  34. [R56] 1/5 · US “The game”: It can’t get out of the adds. I get it that the adds support the game. But, when you have to click the “X” 3 to 4 times to get out of the add, or the newest one. Put the X right next the link to the add. Click, get the company, close, click the X, get the company……. Can you get this program with out the adds. I see nothing about that.
  35. [R33] 2/5 · US Same Stuff Over And Over: I have done the same things over and over for months now. What’s the update for if there isn’t anything new?
  36. [R53] 1/5 · US Heavy programming slows app: This game is so much fun! It’s too bad the way it is programmed slow it down and makes it buffer especially on the puzzles to get more keys. ADS GARLOR. No way to pay and not get ads. BAD. Ads at bottom of the screen is probably the reason it locks up all the time. Overkill. Ads between games and bottom of screen is the problem. Pick one and stop being greedy.
  37. [R143] 3/5 · GB Great game: I’m really enjoying this game and can play it all day long. However I have issues with it because the app is slow in responding to my clicks and I loose lives. The same for the keypass game. Pls guys look into it. It’s a great game gets my brain going
  38. [R182] 3/5 · GB I love this game, but….: I love this game, however I’m finding that it lags so much! It’s slow to react to what I’m doing, such as zooming in and moving side to side. I end up losing lives because where I have pressed to move the image, it’s so slow to catch up it thinks I’m clicking on the wrong thing. It’s hard to explain but it bugs me so much because I do LOVE this game
  39. [R19] 3/5 · US Question: I haven’t played this game in a while but loved it when I used to play. I don’t remember there being so many ads but also, I don’t know if it’s just me but the music doesn’t play anymore. The music you guys had for the in-game play used to be so calming and helped me focus. Did you take it out?
  40. [R7] 5/5 · US Get it done: It is quick, easy and Fun!
  41. [R63] 1/5 · US Insane Amount of Ads: I get it, every game relies on ads to make money these days, but even among the worst, this app has them all beat. It lets you play a few round without ads to start, then around level 10 or so, they hit you. Ads after EVERY. SINGLE. LEVEL. And I’m here to tell ya, the average level takes about 20 seconds to spot the 10 differences. Then it’s a 30-second (or longer) ad. You’ll
  42. [R70] 3/5 · US Ads: The ads that play at the bottom of the screen are insanely annoying. This is the only app I’ve encountered that constantly plays (with sound) ads at the bottom of the screen. Even if you try to pause the ad or turn off the sound, a new one starts like 5 seconds later. This isn’t a problem when I’m using my phone sound because I can just turn off my volume, but I like to listen to podcasts whi
  43. [R155] 3/5 · GB Great Game but drains the battery: I love this game and find it really quite addictive. It also does make you more attentive to detail. However, the game really hammers the battery and if you are unwise and leave it running in the background it drains the battery completely in a couple of hours. Developers - can you fix this?
  44. [R108] 3/5 · GB I like the game: But £15 to remove ads is extreme. I usually purchase this for enjoyment purposes but not at that price.
  45. [R47] 1/5 · US Fun…until: Great game, but you constantly have to get more keys and play a different jigsaw puzzle game in order to get more. Very annoying. It’s a shame, but deleted the app for this reason.
  46. [R81] 2/5 · US Not as good: Thai game used to be really fun for me. I recently picked it back up, but it’s pretty unplayable now. To get “keys” to unlock the next level, you have to play a side game (which is a big pet peeve of mine) to even play the actual game. Definitely did not used to be this way. if the mini game was shorter I’d be fine with it but it takes me longer to play than the main game, so frustrat
