Numberzilla

55
Value score / 100 Worth paying? Depends It depends

Numberzilla is a fun and addictive puzzle game, but it is plagued by severe technical issues like crashing and lagging, which significantly diminish its value, especially for free users due to excessive ads.

Free + in-app purchases seen up to $520 4.3★ lifetime (66,008) since 2019

Numberzilla offers an engaging and relaxing puzzle experience, but frequent crashes, loading issues, and excessive ads in the free version severely impact usability. While some paid users report improved performance and satisfaction, many still experience technical problems, making the value of in-app purchases inconsistent.

Free vs paid

The free version of Numberzilla is heavily reliant on ads, with users reporting constant interruptions, long ad sequences, and ads appearing after every short game segment R7R13R17R30. This ad frequency makes the free experience frustrating and often unplayable R7R13R17. The paid version, which removes ads, is praised by some for enhancing the game's enjoyability and making it a relaxing distraction R39R45R46. However, even paid users sometimes experience lagging and crashing issues, suggesting that paying does not guarantee a bug-free experience R39R40.

  • The game is praised for being relaxing and helping users unwind or manage anxiety.R15R21R36R43

  • The ad-free version significantly improves the user experience for those who purchase it, making the game more enjoyable.R39R45R46
Worth paying if

It is worth paying if you find the game highly addictive and relaxing, and are willing to risk potential technical issues for an ad-free experience R46. Paying might be worthwhile if the game helps you with anxiety or provides a significant distraction, and you are prepared for the possibility of needing to contact support for bug fixes R45R46.

Skip / stay free if

Skip paying if you are not willing to tolerate frequent app crashes, freezing, or lagging, as these issues persist for many users regardless of payment status R2R8R10R11. Also, skip if you expect a perfectly smooth experience after paying, as even ad-free users report performance problems R39R40.

Evidence note: The reviews are heavily skewed towards recent technical complaints, especially crashing and lagging, which contrasts with the high lifetime rating. Many positive reviews are short and lack detail, while negative reviews are specific about persistent bugs and ad issues.

  1. [R7] 1/5 · CA Constant Ads: Can barely play the game with the number of ads. Completely ruins the flow of the game and is more annoying than the game is fun.
  2. [R13] 2/5 · CA 1 minute and a half: Are you kidding? One minute and a half of ads for a 10 second game?
  3. [R17] 2/5 · CA Fun game but WAY too many ads: The game itself it very fun, but there are WAY too many ads. It kinda ruins it after a while.
  4. [R30] 1/5 · CA Disappointing: I get that games have to have ads when you don’t purchase the game but to have an ad pop up after I have to ad a line to my game is just wrong! At least allow a person to play a round before hitting them with an ad!! Going back to the 2048 game I play at lease there I can finish a round before being getting an ad …. There is nothing worse than being bombarded with ads!! Sorry
  5. [R14] 1/5 · CA Mirth mansion: Your mirth mansion ad will NOT exit out! I have to restart the game every time! It’s very frustrating .
  6. [R37] 1/5 · CA Ads won’t load my rewards: Ads won’t load my rewards after watching. Keeps crashing. Emailed the app and still no response or fix
  7. [R3] 4/5 · CA Love the game: I love the game! I just wish I could match pairs diagonally like other games do. I wish that there isn’t a maximum amount reached. I’d like to play the game until I remove all the numbers
  8. [R42] 3/5 · CA Undo button: I really love this game and the new coloured numbers is really great, but I don’t understand why the undo button was removed. This was my favourite relaxing game to play before bed but without the undo button it’s infinitely more frustrating and stressful. Not really sure why you would remove such a simple mechanic, seems unreasonable. Could you add a relaxing game mode that offers th
  9. [R39] 4/5 · CA Super fun game but super laggy: I’ve been playing this game for a while now and have always enjoyed it. I paid to remove ads. I had a classic game last about 2 weeks before the app glitched, crashed and restarted. Now it’s super laggy and takes a solid couple seconds to register that I’ve chosen numbers sometimes won’t.
  10. [R40] 1/5 · CA Was My Favourite…: This used to be one of my favourite games. I have the ad-free version but the app has gotten so slow and laggy that it’s almost impossible to play now. Currently running version 5.11.0

  15. [R21] 5/5 · CA Awesome: I like the challenge without being timed.
  16. [R36] 4/5 · CA Love it but…: Love the game. Helps me relax and pass time! Only issue I have is with ads at the moment. Watched about 200 ads in the last week without getting the rewards. There seems to be a bug
  17. [R43] 5/5 · CA Relaxe: Love this, relaxes me when I get home from work!
  18. [R45] 5/5 · CA Updating my review: I loooove this game. It’s very addictive. Had previously given a lower rating because my game was very laggy and unresponsive after an upgrade. The support team has me all fixed up and were very attentive. Top notch service. My game has been reinstalled at its former glorious speed, along with no ads (best purchase ever). I’m very happy.
  19. [R46] 5/5 · CA Love ❤️: I am literally in love with this game! Best purchase I’ve ever made was the $13/week subscription. I struggle with Anxiety and this game was recommended to me by a coworker just over a year ago. It helps keep me calm, and distracted from whatever happens to be causing me heck. Not only does it help with my anxiety but it is a great time passer! 🤪 One thing I’d like to see is maybe an even
  20. [R2] 3/5 · CA Game crashes: Love the game, but it takes over 20 minutes to get the game to even load in the first place
  21. [R8] 1/5 · CA Broken: App loads up, then crashes. Every time. There are tons of reviews here citing and email to reach out to for assistance, I have reached out twice in the last month and never even got a reply

  23. [R11] 1/5 · CA Locks up all the time: It’s difficult to enjoy this game because it frequently locks up which is frustrating - it would be nice to not have this issue.
