Knock Balls! is a simple, relaxing game that many enjoy for passing time, but it is severely hampered by an excessive number of ads in the free version and reports of the paid ad-free option not working as advertised.

Knock Balls! offers a simple, engaging, and relaxing gameplay experience, but it is plagued by an overwhelming number of ads that significantly disrupt play. While some users find the game enjoyable for stress relief and time-killing, many report that the ad frequency makes it unplayable, and there are complaints that purchasing the ad-free option does not remove all ads.

Free vs paid

The free version of Knock Balls! provides access to the core gameplay, which many find relaxing and a good time-killer R7R15. However, it is heavily monetized with an extremely high frequency of ads, often appearing after every level or even every few seconds, making the game frustrating and nearly unplayable for many users R1R2R8R11. The paid option, priced at $3.99 or $7.99, is intended to remove ads and potentially offer other benefits R21R30R44. However, multiple reviews indicate that purchasing the ad-free version does not consistently remove all ads, with some users still experiencing ads after paying R21R76R112. Additionally, some users report issues with the game freezing or not advancing after completing levels, which can lead to frustration .

Skip / stay free if

  1. [R21] 5/5 · US No ads: A paid 599 for no ads and a bunch of other stuff. I still gotta watch a lot of ads what’s up!! Also the app I bought said it was going to be 499 and it was 599 again what’s up!?!?!
  2. [R76] 1/5 · US Disappointed: I pushed the ad-free button and purchased it & it’s still showing ads…. I recommend you guys to not purchase it. Waste of $3.99
  3. [R112] 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!
  4. [R1] 4/5 · US ADS: I really enjoy the challenge of this game but if you enjoy an ad after every third board this is the game for you, not me
  5. [R2] 3/5 · US Irritating: I played this game years ago and it was. Now to 1 or 2 levels and watch ads. Definitely more ads that game time.
  6. [R8] 3/5 · US It’s ok: Would be 5 start if there wasn’t a ad after every freaking level this is why no one likes mobile games there riddled with ads
  7. [R11] 1/5 · US Pappy: This game sucks because of all the ads
  8. [R44] 3/5 · US WAY TOO MANY ADS: The game is fun and cute but having an ad pop up EVERY round gets real tiresome. I’m still trying to weigh the difference whether $4 is enough to get rid of ads or just delete the game altogether. Why can’t you lower the price of “no ads” and possibly more people might purchase the option. Most games I have played, the “no ads” price is usually about $1.99. Just a suggestion…
  9. [R275] 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
  10. [R4] 5/5 · US This is the best game I ever seen: That game you can tap it and shoot it and what ever you wanted for. This game is so awesome and I love this game.
  11. [R5] 5/5 · US Migh tee: Fun and engaging
  12. [R7] 5/5 · US Love It!!!!: I’ve been playing Knock Balls for years now and I find it very relaxing but still challenges my.
  13. [R15] 5/5 · US Mr. ChollyHoss: I like this game because it’s calming. Instead of me hitting and smashing people around, I play the game. I like discovering new ways to use less balls to knock down the blocks. Thanks for the game !!!
  14. [R30] 5/5 · US Fun With Strategy: This is one of the best games I’ve ever played! After playing it 2 or three times, yeah, I did notice all the ads, but I figured if I enjoyed it this much I’m going to pay the three dollars to go as free! Definitely worth it! I have it on my iPad and my cell phone and love it. It’s something like bowling except this set up is different each time and architecture - (where to find
  15. [R84] 1/5 · US I don’t. Get it: There is something satisfying about hitting the blocks but I don’t understand the point of the diamonds. As far as I can tell there is nothing to do with them. Also, now the game is littered with ads. I’m ready to delete it after waiting literally years to figure out the point.
  16. [R163] 3/5 · US Ads to play ratio is too high: The game play is interesting, and it’s well done from a physics standpoint. But ads are more time than the gamepla.
  17. [R16] 3/5 · US Great time killer BIT: It's all the same!!! The graphic is not super complex so more diversity would be an easy job.
  18. [R35] 2/5 · US fun but: this game is fun, but i’m getting tired of playing the same 5 setups for the past 150 levels!!
  19. [R41] 3/5 · US Repetitive: Fun game but gets old quick. It's just the same levels in a different order over and over
  20. [R54] 1/5 · US Too many ads: Way too many ads. Only a few levels that repeat. Uninstalling
