Community Insight:
There are less than 500 reviews of this game? Cannot believe you havent played this incredible game, one of the best of all time! The world needs more games like this,.
Seriously the best. The puzzles, the game mechanics, even the tranquil soundtrack. We love everything about this game and the other Quell games. We wish they would make more.
This is one of our favorite games ever! We have all three; quell, quell reflect and quell memento! However, we just got an iPhone 15 and we cant close the app after opening it. Even the power button fails. Its like the app takes over control of the phone. We end up having to ask Siri to turn our phone off for us.
Challenging and fun to play! A bonus is the soothing background music. Great for visual learners but anyone will enjoy this game.
Awesome game! Relaxing until you get frustrated You have to put it down for a while and when you come back, you can figure it out. Very satisfying to complete a level.
We have been searching for games that challenge, but dont make us feel like an idiot. This game teaches as you patiently work that bubble towards your prize pearls! And when you have exhausted all your trials and finally want to move on or learn what the heck to do, its not bad to ask. No adds..a blessing. One of our all time favorites.
Love this game after a long day of talking with clients: great calming music; game requires focus & concentration but uses a completely different part of our brain. Always thrilled to find new challenging, but not impossible, puzzle games.
This is our first time playing a Quell game and Im glad we chose to try it out. The puzzles are well thought-out and fun and the soundtrack is nice.
Yes, we love them. We bought all Quell games for our Kindle in 2013, bought again for our phone, then again for our iPhone, then iPad. They are beautifully executed, wonderful to play, challenging to solve, and thoroughly enjoyable to rest in as you try to beat the odds. Yes, we know we could have transferred them from one device to another, but we wanted to give Fallen Tree the $$$$ out of appreciation for such a stunning game! Thank you, give us more like this.
No amount of words could describe how brilliant this series is! However, we didn't like how if you wanted to buy the Jewel Detector and the Super Rewind, you had to buy them for each game separately (which was kinda bothersome), but otherwise, it's one of our favourite puzzle series.
We remember when we were younger that Id play quell momento on our parents phones. It was so fun and really made us think. And now that Im on our own and remembered that beautiful game with a great story we wanted more. And this has definitely made us happy. Its a nice relaxing game.
We bought all 4 games years ago, first on Amazon Appstore, then in both IOS and Google Play Store. Now we want to play the games on our Ipad Mini 4, but cant find Reflect anymore. Why? Sorry for the one star, but theres no option of contacting the developers privately that we can find.
This is an exceptionally good game compared to most games we have played in the past. This game teaches you to the think in different mindsets and to see in different perspectives and we love that. Its a very challenging game with all sorts of twists and tons of different levels and stages which is just what we need. There are no ads or in-app purchases like in most games people play so that makes it so much easier to play the game and have fun. This game is most unlike any game we have ever played so thank you for making this great and amazing game. Yours truly, A fan.
We never tire of the game. Our all time favorite.
We love the Quell games. Our daughter recommended them to us as an engaging way to relax and cycle down from a stressful day.
Love this game!!!! Playing all the time we will down load the advanced app as soon as we have all the levels done, hope you keep making more great games like this. We're 54 years old and love thinking games like this. Please make more',!!!!!'!!!!!!!!!!!! We're now 61 and still playing this game. Best game out there.
Relaxing and challenging at the same time. The music is calming. As one review mentioned, no pressure other than what you put on yourself. Great brain exercise AND NO annoying commercials. Well worth the money.
Every few years we go back and play these again! The Quell series is wonderful! The music and sound effects are soothing, the different challenges hold multiple levels of difficulty, and the mechanics are fun and simple! Easy to learn, tough to master! Absolutely wonderful game.
Relaxing. No time limit. Very enjoyable – and addictive.
Am excellent game that is quite relaxing to play. Not too hard, not too easy. Definitely worth the price.
We love this game, there are 4 sequels, we want MORE.
Definitely a game that relaxes without being boring.
We started playing Memento while we were pregnant to unwind. Our now 4 year old son wants to play it together before bed. The puzzles get more and more difficult but its a fun challenge that even our 4 year old enjoys. He likes to find the hidden jewels and we like to solve in perfect moves. So we play all the various versions as a bed time routine. Calming music. Its a great challenge.
Serial puzzles of increasing difficulty without a time limit or restriction from advancement for not achieving the optimum number of moves. Challenging, logical, and visually very tidy. Just our cup of tea.
On of the very few puzzle games that aren't match 3 or bubble shooter. Also, no annoying ads without the option to buy off the ads. We're about 75% able to solve the puzzles. :-).
… A unique and lovely passtime.
What a great stress reliever and a great way to wind down at day's end.
The Quell games are the most thoughtful, engaging, and pleasantly challenging games we've found to play on our device. The game mechanics are creative and involving. The progression perfectly balances training and challenge. One last note: we play almost all games with the device muted, but Quell is the exception. The warm score by Steven Cravis is soothing and haunting all at once.
It's deceptively simple and ridiculously difficult at the same time. It's been a much played puzzle on our phone for about the last three phones.
We have have played all versions several times. Never gets old and challenges our brain.
It really keeps you on your feet.
We love all these games. They are challenging but in a peaceful way. We like how they let us try over and over again until we get the result we want. Still can't figure out how anyone ends up with fewer than the listed number of moves but maybe someday we will.
Nice variety of puzzles. Very well designed. Haven't become bored yet.
Easy to learn and play, with puzzles that challenge on multiple levels. Nice graphics and sound. An all around lovely game.
One of the best games we have ever played! So much fun and challenging as well.
It's relaxing, takes thinking and planning. We haven't been frustrated to the point of giving up, which often happens with games. Nice job.
We can honestly say we love everything about this game. It's so simple and comforting. From the sounds the droplet makes when it's collecting pearls to the achievement of your goal or the failure to find the solution. The sound effects are great and we also love the color palate too! Overall this game comes together to create a whole new experience.
These Quell games are affordable and fun. Very addictive and relaxing. We bought everyone of them and although they are similar, it is just fun.
Moving a jiggly bubble around, peacefully puzzle-solving, providing opportunity for whiling away large amounts of time.
Enjoy playing and the relaxing guitar picking.
Simple gameplay with polished visuals. The game's ambiance is nearly mesmerizing. The puzzles vary greatly in difficulty, some taking only seconds to solve and others requiring up to ten minutes of patient calculation. The sequels look unique and ambitious, and we look forward to trying our hand at them.
Just the right amount and difficulty of challenges, lots of variety from level to level, no time rush, no ads, AND relaxing music. The perfect game for us.
What a fun and relaxing game. Love it.
Just two days into this game, think it's fantastic! Not only challenging, but relaxing.
Nice variety of levels. Definitely gets harder as you go along, but the variety keeps things interesting.
What an amazingly fun and challenging game. It is so fun trying to get the gold @ each level! You are doing an amazing job with this app! Keep up the GREAT work! Blessings.
We think this is a vastly underestimated game! We really love the way you have to think your way around these problems.
Great fun with a bit of frustration mixed in. Some seemingly simple puzzles are surprisingly challenging.
This is a series of puzzles. They are quick yet challenging. We enjoy it. Right on.
This is by far the best game we have played. Sooo thrilled to find one we actually like to play. It starts out super easy but gives a chance to learn. We hsve played for two nites and up to level 10 we think. No glitches,problems ar all just very intriguing puzzles, very thoughtful, the higher we go. Hoping we can find something similar altho will replay this one.
