With gameplay ranging from simple and relaxed to challenging and frenetic, Flow Free is the perfect way to sharpen your logic.

Dinsun Expert Review

Our Expert Score

91/100

Flow Free is a puzzle game in its purest, most addictive form. The concept is so simple a child can understand it—connect matching colors with pipes—but the execution is flawless. It’s the perfect 'one-minute' game that somehow turns into a thirty-minute session. The satisfying 'pop' when you complete a circuit and the clean, colorful grid make for a very relaxing experience.

The game's genius lies in its massive volume of content. With thousands of levels ranging from tiny 5x5 grids to massive, brain-bending layouts, the difficulty curve is expert. It never feels unfair; it just requires a different way of looking at the board. It’s a staple for any mobile device and a gold standard for the 'connect-the-dots' genre.

One of my top puzzle games if not the top
Thu Feb 07 2019 Telula002

I love this game. I’ve been playing since it came out. I’m a puzzle lover of many varieties. I literally have trouble going through a day without doing some sort of puzzle, and that’s not counting the ones I do in my head given any free moment. When this game came out it completed a part of my life (that’s a lot to put on an iPhone game, but it’s true). I play this game every night because it helps calm my mind from my severe insomnia amplified by chronic pain. Flow is the perfect amount of distraction/stimulation, peaceful and soothing puzzling with a perfectly dark background which means it doesn’t wake me up more from the screen lighting. Also my brain now makes up flow boards on tile floors and ceilings, it’s infiltrated how I think. I do flows in my head when I’m in a lot of pain but can’t use my phone, or as meditation or help calming anxiety. My one hope is that you please make more of the LARGEST board puzzles and NOT the courtyards, worms, ink blots etc because even though you think those must be harder, they are actually easier because it gives less room to maneuver leading to much more obvious paths from dot to dot. They’re too easy, along with the smaller board ones, I don’t even have to try with them, such quick solves that my hand gets sore.. But the Largest boards (with no frills) are more difficult and at least provide a bit of a challenge. Please, please give us more large and difficult boards 💜 (either way I’m still keeping this game forever so please don’t ever leave the App Store 😅)

One of the Best Games!

I love this game. I’ve played it for over a decade now. Now my 5 year old daughter also plays it with me and loves it. I haven’t purchased anything with them, but never run out of levels or challenges with the free levels. I also don’t ever get ads. I appreciate this so much! I can actually unwind and play this game - and actually play the game! I’m also not forced to purchase something constantly or have pop ups. It’s also quick to go from level to level. I love there are various options of style of play as well. Having the different sets too lets me play this app as well with my daughter without affecting my ability to play harder levels or mess up my progress or make it too hard for her. While it’s on her iPad as well, we enjoy the brain challenge on the go using my phone. Which is super nice to not have to download a kids app onto my phone just for her and take up space but can both share this app at our own levels. Has been an awesome game for years and the longest running game I’ve ever used and quality is improved with time. It’s nice as the app has increased in downloads and appeal that they haven’t restricted ability to play from what was offered previously unlike many apps. Best game! And so many options of play!

I love it 🐶🐶👍🏻😂😃😀😄😁😆

This game is awesome. I love it I think it is the most relaxing game ever!!! I love it in my free time I will get my phone out and play it. It is like so relaxing one time I fell asleep playing it. I think that if you are looking into getting it you should it’s so nice . It’s all free too . And the best part is I have never seen more then five adds a day. It’s not like one of my other games that is full of adds. I’ve also never seen a bad add it’s only been good adds. Another thing I love is every day there is a daily puzzle. I love to play this. I would have to say this game is probably in my top five favorite game. I have been playing this game for over six years never once had any problems with this I decided to write a review because I’ve been stuck in my house a while I’ve been playing this game like crazy. I decided I would write this review because all these years of playing I haven’t said anything about it so I just want to say flow free you have done an amazing job at this game. I love it !! Thank you so much for creating this game I hope you can put my review on for others to read and find out how good this game is ! And I just wanted to say YOU SHOULD DEFINITELY GET THIS GAME !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

An Amazing and Creative Game
Sun Nov 10 2019 Nabee ❤️

Flow free is a game where you have to connect lines. You have an amount of moves and it shows your best amount of moves for that level. What makes this game great is that it is logic and common sense. Also, it’s the fact that it helps your brain really think which two lines should go where so the other lines connect. This is also satisfying seeing them connect. Another thing I like is how they always get harder level by level and scoreboard by scoreboard. I like the idea of them creating daily challenges. The game is perfect really. It’s very creative and really causes your brain to think. It’s like a fun, creative, brain game and I like the idea of that. One thing that flow free should add is a challenging level where you have a certain amount of time to connect 20-30 lines. Another thing should be versing other players to see who can connect the lines or complete 1 entire scoreboard quicker. These two game modes should be called “Expert Level” and “Competitive Level”. I hope flow free can use one of my ideas. Therefore, this game is great but can use a couple game modes. Once again, thank you for reading this. -Nabeeha. A

Wonderful app!
Mon Jul 10 2023 KittycatJK

I have had this game for a few years now, switching to newer devices from time to time. It has remained on my iCloud and I now have all of the Intro section completed. When I got this app on my new phone (which, happens to be older) it immediately asked me if I wanted to link to my iCloud. Almost all of the other apps I downloaded again to this phone didn’t ask me, nor sync to the iCloud. This caused me to lose a lot of game progress on other apps. It was relieving to see that it synced, to say the least. It has been a pleasure to sit down and play the game, with the short logic puzzles being addicting. As said before, I have spent years completing every single puzzle. There are 300 puzzles in total, and I frequently forget about said app. I have yet to complete the other expansions (links, hoops, manias, etc.) There are not many ads, neither, so that simply adds to the experience. You can build your mind and brain, with flourishing colors. What I am trying to convey is that this app is a beautiful, calming environment. I would recommend this app to others, absolutely.

Review + Suggestions (my opinion)
Wed Jul 02 2025 Nahte__

This game is entertaining, it passed the time when I was bored. Also, the variety of packs will keep me entertained for probably a long time. As well as that, the time trial game mode is fun but also stresses me (in a good way), which I like. However, I’d like to add one suggestion, and it doesn’t really have to do with the actual game, but instead with the packs. That pack is the links pack. I really like it, and I was a little disappointed when I found that there wasn’t a separate game for the link pack. So I suggest that you make a separate game from Free Flow with only chains. This might be an unpopular opinion, but I’d really like to have a separate game with only links. There’s nothing wrong with the game whatsoever, but I’d like to have a Free Flow links game. I suggest the name “Free Flow: Links”, which would probably be the best name for it. I also want to give you ideas for it. Maybe rectangle puzzles or weirdly shaped ones like in Free Flow: Shapes. Maybe add a gimmick, although you don’t have to. It’s also fine if you don’t make the app, but I strongly suggest that you make it.

‼️ Suggestions
Tue Nov 22 2022 mynicknamewasstolen!!!

Still love it! I have 2 suggestions, but I don’t know how difficult it would be to carry through: One of the issues I have with playing this game is recalling which color I last played. So, for instance, say I have only two lines left to complete on a very difficult puzzle (and, those are the best kind…the games that make me use my head). Let’s say I realize the yellow line should actually go down just a bit further and wrap around the blue dot. But if the yellow wasn’t the last line I played, I have to start all over. But if it was, I can readjust and play the rest of the game. It’s not a huge issue…maybe saves a few seconds. My suggestion was to add dots on the top of the screen, which tracks which color we used last. But then this brings me my second suggestion: to possibly “undo” the lines in backward order to replay. So the dots at the top of the screen-should you choose to honor that request-would show that I played red…dark blue,,,green,,,yellow…white. And if I felt I messed up on the green line, I can tap the white line to undo, then the yellow line, then green…then I redo the green…then redo the yellow…then redo white…and then continue to finish out the game. So the sequence of dots at the top would come in handy here, also. But the game is very fun. I’m still playing the games on two devices with both hands forward and backward at the same time. The only version of the game I don’t like is the warp that has a plus-sign shaped box. I find it very difficult to complete. But I always find the solution … it just takes me about an hour to find it…and always on a day when I don’t have time to play it. Yet, I can’t let it go. 🤣 So whatever you decide to do with this suggestion is fine with me. I would still love to have a version where we can design our own puzzles, even if the puzzles we design can only be played by us, who designed them. Thank you for a job well done!
