  2. [R5] Flow Free 5/5 · US Great: It’s good for your brain and the controls are easy to understand.I highly recommend it for your children.
  3. [R17] Flow Free 5/5 · US The best game: That is really really, really really good. I like this game if you were looking at the comments right now it’s a really good game and it’s kind of a brain puzzle. I really like it. I think you all should try it.
  4. [R29] Flow Free 4/5 · US So many levels: I love how many levels and variations there are! One thing I could do without is the ads.
  5. [R1] Flow Free 2/5 · US I hate ads: To many like way to many ads.
  6. [R3] Flow Free 3/5 · US LONG ADDS!!!!!: The adds last longer than the actual time I’m playing the game sometimes it feels
  7. [R4] Flow Free 1/5 · US Ads Galore: I first played this in 2nd grade and I enjoyed it. I installed this again. I’m in 8th grade and disappointed. This game has a plethora of ads. And these aren’t your typical ads. They last a MINUTE. Every two levels you get an ad. Super sad for a good game. Can’t our hints like, replenish the next day? That’d be better than having to suffer through a minute long ad. Edit: SOME OF THE
  8. [R7] Flow Free 1/5 · US Scam: Game is fun but also a scam. After I bought the no-ads version I still have to watch stupid ads to get a hint. This is really annoying and disappointing!
  9. [R15] Flow Free 3/5 · US Ads: Fun game but ad plays after every level. 75% time the ad close button opens safari. Ad won’t close!
  10. [R19] Flow Free 1/5 · US Tons of ads & stop working: I used to love this game. Even my 11 and 12 year old loves to play it. But there’s so much ads. What’s even worse is that the game stopped working, yesterday. I no longer can get and play any of the daily and weekly games. I was thinking about purchasing the other games that they have. But when I click on purchase, there’s no price tag to inform you how much you will
  11. [R22] Flow Free 1/5 · US App stopped working: The game stopped loading for me today and I’m going to lose my daily streak :(
  12. [R28] Flow Free 1/5 · US Game Stopped Working Today: Been a daily player for a LONG time. It just stopped working today June 26th. Hopefully it gets fixed because I have a daily streak I don’t want to lose.
  13. [R9] Flow Free 3/5 · US Expensive and a little confusing: It’s a really good game but the settings should show what turning on and off does to it. Also the micro transactions should be cheaper so they get more sales and the other person thinks it’s a good deal and it’s a win win for everyone
  14. [R10] Flow Free 1/5 · US I hate this game lol: I never win anything in this game so I’m not even sure how to play this game anymore because I’m not even a fan of this game and it’s so hard to win anything else whoever made this can you please just make this game better and easier. Love ayva0618 P.s.can you make a new game that is about me and my friend who is Abisai
  15. [R34] Flow Free 1/5 · US No I hate it: To many ads , very boring and it is confusing, LALALALALALALLALALALALAALA. hehehehehehheheheheheheheehhehehe giggle giggle giggles
  16. [R12] Flow Free 3/5 · US Too many ads: The game is fun but after every game you win, there’s an ad then you get to play another game then there’s an ad and another game and there’s another ad that’s ridiculous. That’s more stressful when you’re playing a game that’s supposed to be distressing you. I would imagine maybe after three games in a row you can have an ad but not after every game.
  17. [R13] Flow Free 1/5 · US So far, very unhappy: I bought the Ad free version, yet the Ads keep popping up. I HATE THAT!!! Can you please get rid of these ADs
  18. [R50] Flow Free 5/5 · US Will Not Stay On Game: I paid for game of Free Flow. For some reason after I play first game it sends me to Royal Kingdom and will not let me go back to Free Flow. I am really upset that game I paid for to remove ads is giving me nothing but ads. Bummer.
  19. [R68] SortPuz 5/5 · US No Forced Ads: I like water puzzles but hate forced ads. Had to pay $2.99. Guess $3 is not that expensive to limit ads to optional viewing.
  20. [R43] Flow Free 1/5 · US I'm really just heartbroken: I got so far into the game where i unlocked so much and it stopped working on my phone. I deleted it knowing i will have to start all over again but it still won't work. I would play the game like an hour a day durning school because it was the only thing that would work. deleting it was the hardest thing i had to make myself do but I did it just to be hurt all over ag
