Knock Balls!

User verdict / 100 High confidence Divided

Knock Balls! is a simple, addictive time-waster, but recent updates and an overwhelming number of ads, repetitive levels, and unspendable in-game currency have significantly degraded the user experience, contradicting the lifetime positive rating.

Knock Balls! is a free-to-play game where users knock down structures with a cannon. While some find it a satisfying stress reliever, recent reviews highlight a significant increase in intrusive ads, highly repetitive levels, and a lack of purpose for collected in-game currency.

What the developer says changed (the verdict above weighs this against what reviewers report):

Overall optimization.

Recurring themes

Ads negative
Users overwhelmingly complain about the quantity, frequency, and intrusiveness of ads, often appearing after every round, mid-level, or being unskippable. Many report deleting the game due to ads, even those who paid for an ad-free version still experience them. The developer's 'overall optimization' update did not address this, and in some cases, ads became worse.R2R4R8R10
Repetitive Levels negative
Many long-term players and even newer ones find the levels to be highly repetitive, with the same target patterns and backgrounds appearing over and over. This lack of variety and increasing difficulty makes the game boring and monotonous, despite reaching high levels.R1R6R12R14
Useless Currency negative
Reviewers frequently question the purpose of collecting diamonds or gems, as there is nothing to spend them on. This makes the bonus rounds and currency collection feel pointless and contributes to the overall lack of objectives.R6R23R25R35
Freezing/Crashing negative
Users report the game freezing, particularly after ads or during specific segments like the chest, requiring them to restart levels or the app entirely. This issue is present on both iPhone and iPad.R31R49R57R75

Who it's for

This game is for users looking for a simple, mindless time-waster to decompress, particularly if they are willing to play offline to avoid ads or tolerate frequent interruptions R12R18R29R34. It might appeal to those who enjoy basic accuracy challenges R12R13. This game is NOT for users who expect varied levels, meaningful progression, or an ad-free experience, even if they pay for it R2R4R12R39.

Evidence note: The recent reviews skew heavily negative, particularly concerning ads and repetition, which contrasts with the high lifetime rating. This indicates a significant decline in user satisfaction over time, possibly exacerbated by recent updates. The developer's notes for 'overall optimization' are vague and do not address the specific issues reported by users, and in fact, many users report a worsening experience after recent updates .

  1. [R12] 3/5 · US Needs some updates: I paid for the ad free version, otherwise this game would have been deleted by now. It’s a nice time waster. Great fun for trying your hand at accuracy. It’s March though, and why am I still playing it with Xmas backgrounds? Needs some new challenges. You end up playing the same games over and over and then it can become boring. Do some updates on the game!
  2. [R18] 4/5 · US Game: Perfect for when your bored and really fun to
  3. [R29] 5/5 · US What i think this game could do for you: I think this game is so fun because when you going through something’s this game really get things of you mind.
  4. [R34] 4/5 · US Great way to pass idle time: Fun have played over 11000 games But wish you would get some new block formations . Gets monotonous Love to play though
  5. [R13] 5/5 · US Great accuracy tester: You must master where the weak spots are in each more difficult structure to get through them lots of challenges
  6. [R19] 5/5 · US Knock balls: Challenging//
  7. [R2] 1/5 · US ADDS😤: soooooooooooooooooooooooooooooooooo many adds. ITS RIDICULOUS. now, it’s pretty fun, but... ADDS🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬👎🏻👎🏻👎🏻🤞🏻👎🏻👎🏻👎🏻👎🏻👎🏻👎🏻👎🏻👎🏻👎🏻👎🏻👎🏻👎🏻 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
  8. [R15] 2/5 · US Knock down balls: Too many Ad’s in the game, can’t finish a game comfortably. Not playing it too much anymore!
  9. [R20] 2/5 · US Too many ads!: Good game way too many ads, can’t even enjoy
  10. [R26] 1/5 · US Perfect if you enjoy ads: This is a mediocre at best. But it is perfect for you if you enjoy ads! At least the developer is happy - they’re making some $$$ on ads, for sure.
  11. [R1] 1/5 · US Lucky it’s only $3.99: I feel like I’m in a video loop, same games with different backgrounds. Not close to what it was a year ago.
  12. [R6] 5/5 · US Stuck with the same targets again & again: This has been a very lovable game, but today it is becoming boring. I have a diamond bank balance of 19,910 with nothing to spend it on. I am at 20.747 level and I’ve been seeing the very same rotation of targets for quite a while now. I am also a paying customer and I will give you a chance to respond; or, bring more of the target patterns back into the
  13. [R14] 3/5 · US It’s k: I like it but it need more things and whatever
  14. [R23] 4/5 · US Surprisingly Satisfying: Maybe it’s the world in which we are currently living, but it’s comforting to knock things over. What are the pink gems for? I have tons. If it’s just to change cannons, that’s lame. I prefer the one that looks like a cannon.
  15. [R25] 1/5 · US Gems???: What are the gems used for?! They seem to be useless! Also the ads everywhere are extremely annoying but I guess that’s what makes it free. :/
  16. [R35] 3/5 · US Fun but no real objectives: It’s fun but there’s no goal to reach, no reason for diamonds to be collected. Make it goals or something, otherwise I’m getting bored.
  17. [R31] 3/5 · US Freezes: It’s a mindless, monotonous game that’s a great way to decompress until the game freezes. This happens at the segment with the chest; after hitting it enough times to pass the segment, it simply freezes. Then I have to repeat the entire level again so the mindless monotony turns into frustration.
  18. [R49] 3/5 · US Ok game: I like the game but after playing two full rounds and going to the map after the full second round my game freezies and I have to go completely out of the game and start again. Can you please check on the freezing problem. I have the game downloaded on my ipad and my iphone I have the same problem on both. Tazzy
  19. [R57] 2/5 · GB Could be 5 stars but let down by bugs: I was enjoying this game, and I don’t mind watching ads as people have got to make a living. BUT every other ad seems to cause the game to freeze. The ad plays but ads won’t respond to touch and I cannot exit them unless I close the app down.
  20. [R75] 2/5 · GB Was a great game ...: Was a great game but after getting to almost 5000 it crashed and all I got was, apparently, 3 empty (cardboard?) boxes at the bottom of the screen. There is no way to contact anyone (that I can see anyway) so I deleted it and started again. Now on over level 4000 and gone down in the leaderboard (with 9000 levels I should be way up there - I can’t figure out how they work out
  21. [R4] 5/5 · US Knock balls: Not fun anymore got so many ads and payed for free ads and don’t get free ads
  22. [R48] 5/5 · US Confused with the ad free: I paid to get rid of the ads. It’s a very satisfying game. I’m off put, however, because there is a banner ad at the bottom of my screen that covers part of the cannon and sometimes my hand touches it. I paid $3.99 for it to be ad free. Something needs to be changed. 3.99 is a bit more than most games ad free version, and its false to say you are paying for ad free.
  23. [R28] 1/5 · US Game would be great if: Too many LONG ads that absolutely GROSS! Every level they show ads! You loose interest before too long because of them! Then there are these ads that even though my sound is off, it BLARES and wakes everyone up! What’s with that? Until improvements I will have to delete!
  24. [R60] 3/5 · GB Sound keeps going off: Love the game but the sound keeps going off I turn up my volume and it comes on for a little bit then goes off again frustrating
  25. [R61] 4/5 · GB Sound: When playing a game and then having to watch a advertisement the sound goes once you return to the game very annoying
  26. [R56] 2/5 · GB Adverts ruin it: I like the game, although rather repetitive each round, after about 5 there’s no difference. The adverts are the reason I’m deleting this game, constant and even in the game between the rounds also shouldn’t be advertising fake games with £1000’s to win when everyone knows they’re false.
  27. [R70] 1/5 · GB My review: This game is overall good but there is inappropriate ads that come up that shouldn’t be allowed they should be banned if good ads can’t be shown then don’t bother showing any ads at all.
  28. [R93] 4/5 · GB Mr: Not sure if you’re aware. But one of the pop up ads on this call ‘fachat’ literally has what looks like under age girls dancing provocatively on it?
  29. [R8] 5/5 · US Good game: But It has to much adds
  30. [R10] 4/5 · US I Love the game but...❤️: I really love this game but there’s a lot of ads .sometimes after I’m done being in one lab for half of the section and it pops up an ad the game is really fun and I like all the different styles, please fix the ads.🏳️‍🌈
  31. [R39] 1/5 · US Ads: Great game but the ads just over kill. They are so long and non skippable that you are stuck watching them. By the time they are over you are aggravated and don’t want to play anymore. Thanks but no thanks And it’s that same thing over and over and over and over and over and over and over and over and over and ooooovvvvvvveeeeeeerrrrrrrrr. Why are you guys not adding new levels? I’m at like
  32. [R125] 3/5 · GB Irritating cash cow: This game is amazing. Love playing it, all the time. My issues with this game are: - The adverts are sooooo annoying! At the end of every round is a 30 advert! Rounds are over pretty quickly! - The adverts are designed to be so annoying that you pay to remove the adverts (don’t mind this) - Not paying £3.99 to remove adverts!!!! - What are the diamonds for? I keep building
