Latest update · v3.72

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

Bug fixes and game optimisation

Recurring themes

Ads negative
The most prevalent complaint is the overwhelming number of ads. Users report ads appearing after every single game, sometimes even upon launching the app, making gameplay frustrating and often exceeding the actual play time. Some users who paid for an ad-free experience still encounter ads for missions or other features, leading to accusations of deceptive practices. The developer's notes mention 'game optimisation' but not ad reduction, which contradicts the user experience.R7R9R13R15
Performance Issues negative
Many users report significant glitches, lag, and freezing, especially at crucial moments during gameplay, causing them to lose. This issue is frequently linked to ads loading in the background or the game purposely slowing down to penalize players. Despite the developer's notes mentioning 'bug fixes and game optimisation,' recent reviews indicate these problems persist or have even worsened, with some users noting the game runs worse on newer phones than it did years ago.R12R18R35R44
Relaxing & Addictive positive
Despite the issues, a core group of users still find the game very relaxing, satisfying, and addictive. They appreciate its simple concept and ability to help pass time or relieve stress. This positive sentiment often comes with a caveat about the ads or glitches.R1R3R5R8
Monetization & Content mixed
Users express frustration with the monetization strategy, particularly the high cost of in-game items like skins and the perceived 'scuzzy' nature of selling lives. There's also a desire for more content, such as additional missions, power-ups, or design options, to prevent the game from becoming boring over time.R3R12R21R28
Privacy Concerns negative
A few users raise serious concerns about data collection, with claims that the app sells user data or tracks users. There are also reports of random charges and inappropriate ads.R2R6R39R130

Who it's for

This game is for players who enjoy simple, meditative, and challenging reflex-based games and are willing to play offline to avoid ads R11R30R50. It is not for users who are sensitive to frequent in-game ads, expect a glitch-free experience, or have concerns about data privacy R2R7R12R45.

Evidence note: The recent reviews skew heavily negative, particularly regarding ads and performance issues, which contradicts the overall lifetime rating. The developer's update notes are vague ('Bug fixes and game optimisation') and do not address the specific issues raised by recent users, such as excessive ads or persistent lag, suggesting a disconnect between developer claims and user experience. The privacy concerns, while serious, are mentioned by a smaller number of reviews compared to ads and glitches.

  1. [R1] 5/5 · US I love this game: Get this game very relaxing 100%
  2. [R3] 4/5 · US Almost perfect: Simple but addicting. Just needs more missions to retain engagement and reward system could be reworked to also make players wanna keep playing. Maybe like power ups or something?
  3. [R5] 5/5 · US Best game ever: My brother showed me this game when I was little and I forgot about it, now I re-downloaded it and can’t stop playing it.
  4. [R11] 5/5 · US One the best games: Stack is a fun and simple game where you stack moving blocks and try to line them up perfectly. The gameplay is easy to learn but challenging to master, which makes it really addictive and great for quick games. A helpful tip is that if you turn off your Wi-Fi or mobile data while playing, you usually won’t get ads.
  5. [R50] 4/5 · US Pretty fun, but there are some problems.: This game can be a little bit too basic. It’s really just a game where you stack blocks. It’s fun and it’s really good for testing your reflexes and reaction time. There are ads and they can get pretty annoying, if you don’t wanna pay, turning off WiFi and Cell Service (if you have it) will get rid of the ads, but still lets you play. There aren’t that man
  6. [R64] 5/5 · US A great game: Honestly, this game is a great way to kill time. The graphics are nice to look at, the colors are pleasant, the game introduces challenge, I could go on and on about why this game is perfect. Well done.
  7. [R71] 4/5 · US Want more designs: This is a lovely game. Meditative, elegant, and simple. Great game for when I need to listen to a presentation but want something to do with my hands. I just wish the developers would add to it or enhance it. How great would it be if I could see a whole city of the towers I have built. All of the different designs. Wouldn’t that be beautiful??
  8. [R30] 5/5 · US One of the most relaxing games I’ve ever played!: Very good game and if you don’t like the adds just turn off the WiFi so back what I was saying it’s very relaxing and the skins are good I just wish the -y added more skins and I wish they keep working on games like these because it seems there very good at it!
  9. [R70] 5/5 · US Love it: It’s just like that arcade game in main event it’s so satisfying and can work with no Wi-Fi it’s so good would recommend

  11. [R21] 5/5 · US BEST GAME EVER 🕴️🕴️🕴️🕴️🕴️🕴️🕴️: First of all the game is VERY SATISFYING And second of all there is one problem when i want to do the achievement get a extra life i cant because i need to give money for 13 EXTRA LIFE’S I’want 1 extra life for free.

  14. [R7] 1/5 · US Ads: So many ads not worth it.
  15. [R9] 1/5 · US When did this game turn to 90% ads: Too many ads
  16. [R13] 1/5 · US Garbage: The ads make this unplayable. The developer should be ashamed of themselves and Apple should not allow this BS
  17. [R15] 1/5 · US so many ads: after every turn there is an ad. how greedy can you be!
  18. [R12] 1/5 · US The game purposely cheats and is flooded with advertisements.: Every time you get into the flow or a streak or you stack a few in a row the game with penalize you and become laggy causing you to make your stacks in uneven and the lag will stop once you mess up. It reminds me of going to a fair/carnival and wasting money on the games there because they all cheat you out of your money some how. The
  19. [R18] 1/5 · US Joke now: Game purposely lags so it messes you up. Also riddled with ads. What a joke
  20. [R35] 2/5 · US Good game but to many ads and lag: Like I said it is a good game but it has to many ads and lag to actually have a good time and no one is going to pay for lives and just die so it’s kind of a game that you would not be sad if I got rid of it
  21. [R44] 2/5 · US Ads: Would be nice if it didn’t lag consistently from loading your bs ads.
  22. [R34] 1/5 · US Tf is wrong with you: I had purchased no ads ages ago, opened it up and immediately got one of the loudest most annoying ads I’ve ever heard. Exited out and opened it again. Got a different blaringly loud ad. This can be a nice app to use before I go to sleep and I usually have ASMR playing. An AI blowing raspberries into both ears at top volume when I gave you dicks money specifically so that wou
  23. [R54] 1/5 · US Paid version not really ad free!: I liked the game so much I decided to pay for the “ad free” version. Now I don’t have to watch ads after every game which is nice BUT…. you still have to watch an advert to UNLOCK every completed mission. The developer has got you whether you pay $$ to go “ad free” or not. These are some despicable business tactics and I have deleted the game instead of giving the
  24. [R98] 5/5 · US Love: Obsessed with this game but too many adds and would really like them to make more skins. Plus I just realized I bought no ads x2 and still get ads :/
  25. [R40] 5/5 · US Beautiful: All I can say is I love this game but it gets boring after a while Please add more things and lower the tower prices
  26. [R46] 4/5 · US You should get this😍: Ots great but over time it just kinda gets boring
  27. [R2] 1/5 · US takes all your data: was wondering why there weren’t ads it’s because the app just sells all your data
  28. [R6] 1/5 · US Random Charges: Random charges from this game!
  29. [R39] 1/5 · US Strange: I deleted it because when I was playing it really strange was happening like it said the one time someone was tracking me on it
  30. [R147] 1/5 · GB Too many ads!: This game tries to collect your data!
  31. [R67] 1/5 · US Does not work: Every time I try to play this it always takes me back to my homepage total waste of time
  32. [R72] 1/5 · US app have crash on ios 12.5.7 iphone 6: can not opened after first game play when online. for resolve must be game offline. please fix bugs
  33. [R75] 1/5 · US Please Fix: So lots of my friends have this game and I have played it on their phones and I love this app but when I tried to install it on my device it opened and then after like 5 seconds it closed and sent me back to my homescreen 😭 I rlly want this app to work bc it is rlly fun 💕 But if u can get it to work I definitely recommend!! It is also a great game for long car rides or just when u don'
  34. [R8] 5/5 · US ;): So fun
  35. [R28] 2/5 · US Too Many Ads: Please give us an option to pay for no ads or something. It’s a fun game but the constant ads are ridiculous.
  36. [R130] 1/5 · GB Best game ever but the ads are really inappropriate: I saw about 5 nudes from ads
  37. [R23] 2/5 · US Ads: You have to watch an ad everytime you die and they typically take around 1 minute. Game is fun though.
  38. [R45] 1/5 · US Ruined by glitches: This app is ruined by the fact that the frame pauses to load something in the background while I’m playing, so the timing randomly gets thrown off and causes me to misplace the block. So stupid! Fix it! Why are you loading things while I’m playing!?
  39. [R52] 3/5 · US pretty good but very glitchy: Its fun and engaging with the hundreds of tiles you can unlock, but it is unbelievably glitchy and it makes it very hard to play at times.
