Money well spent. Great for downtime- calming and good mental exercise. I recommend purchasing the games because the adds in the free version disrupt the zen. Very enjoyable! ### 5/5 — Peace, serenity, and mental challenges *2020-03-25, version 1.03* Those seem like strange bedfellows, but I am writing to tell you that they are exactly what you need to relax and relieve your stress. I had downloaded the first 3 Quell games years ago and solved them again and again until it became tedious. How delightful to have new puzzles to solve along with beautiful music that soothes the souls. Great job, folks! ### 5/5 — uff *2019-07-18* diese Rätsel zu lösen hat schöner Weise eine gefühlte halbe Ewigkeit gedauert, vielleicht sollte man nicht versuchen, alle Level perfekt zu lösen. Vielen Dank für dieses wunderbare Rätselspiel mit sehr beruhigender Hintergrundmusik und einer schönen kleinen Geschichten im Hintergrund. Sehr zu empfehlen. ### 5/5 — One of the best games available *2019-07-09, version 1.01* All the Quell series games are perfect. They are calm and soothing yet challenging; they keep the mind occupied with contentment, beautiful music, and beautiful colors. This is the best in the series because it seems the longest, has new elements that are entertaining to learn, and offers probably the most challenging levels toward the end. Please keep making these games! ### 5/5 — Nice additions to a great Series!! *2018-10-28, version 1.01* Ive played the first three games on my Iphone 4S. So that gives you an idea how successful these puzzles are. Each started out on its own before Memento, then they hid Gems in each of the levels (+ series). There’s also Red Portals that take you to a Secret timekeeper level in Memento. One of the additions here in ZEN is: One way portal blocks which you come out of the direction the Gold ring sent you. You can’t go back through a block however you can move it to a new place you want to send stuff in or teleport out of! The SWEET part lies in certain levels you can actually PUSH the block into the Gold Ring that creates & leads to a WORMHOLE level. Everything move you make there is now REVERSED! If you never played any of the Quell series before, you can start with the original to see where the game gets better over time. So if you haven’t got the package of 4 - try Memento first. The original might drive you a bit MAD as there’s less variety of puzzles there & more use of closing gates. However, both original & Reflect each have BONUS levels for extreme challenge too. ### 5/5 — Dear Fallen Tree Game Makers *2018-08-03, version 1.01* Dear Fallen Tree Game Makers, I love the Quell games so so much!!! Please consider adding the following updates to all Quell games: ability to reset apps to fresh, erase memory without erasing prior purchases, tips for how to solve/reach very tricky locations for gems and portals whether for purchase or through a link to a blog about the games and how they are designed. I love Quell games so much that I want to go Behind the Quell! I want to know the designers, what inspired their choices, the colors, the music, etc. Thank you so much for making these games for us to enjoy!!! ### 5/5 — Sensational *2018-06-16, version 1.01* The best puzzle game out there. Hours of fun ### 5/5 — Simply a great game *2018-03-13, version 1.01* I Purchased the multipack and had all four games on my iPad. I found that a very relaxing way to spend a cold winters evenings. I would highly recommend this to anyone I need some time for themselves to be quiet and just relax a little. It is very well worth the money spent ### 5/5 — Superb. *2018-03-09, version 1.01* The Quell series is a significant work of art on all levels. Compelling, comforting, challenging, inspiring.. I would love to have the option to move through chapters at the same level of difficulty as the first level, when I want a purely relaxing experience. As with Memento, I found some of the puzzles too complex to tackle. That said, I'm always looking forward to experiencing more Quell, and I'm grateful that I can turn to these gems that fill my heart. ### 5/5 — Best of the Best *2018-03-03, version 1.01* This is the very best in a series of wonderful games. I have played all the Quell games and honestly thought it couldn’t get better than Memento, but Fallen Tree completely outdid themselves once again. Like the other games, the graphics are smooth, fast, and positively gorgeous. Again, like the other games, the music is wonderfully composed, beautiful, and relaxing. I liked the story aspect of Memento, but did find it a bit vague. I love the letters at the end of each chapter in Zen. They are just specific enough to be compelling, and I love how the story wraps up. I will most definitely play this through several more times. ### 5/5 — Супер!!! *2018-01-25* Жду следующую часть ### 5/5 — Very good puzzle *2017-09-07* But no Russian language. Reading letters is too hard... ### 5/5 — Excellent *2017-08-18, version 1.01* Really enjoyed this game. A combination of logic and lateral thinking. Hope there is another Quell game on the way. ### 5/5 — Top! *2017-07-09* Top! ### 5/5 — My favorite quell *2017-06-11, version 1.01* Solved all the puzzles to the end. Resorted to getting the solution only four times. Sweet inter-level story. Beautiful! Glitch free. ## Most critical reviews (10 lowest-rated) ### 1/5 — Nur schwarzer Bildschirm auf dem IPad *2026-06-13* Liebe diese Spiele. Kann aber auf meinem neuen iPad keines der Fallen Tree Games mehr nutzen. Die Musik ertönt, aber der Bildschirm bleibt schwarz - obwohl das Spiel eigens auch für das IPad beworben wird. Auf dem iPhone funktioniert es, macht aber nicht so viel Spaß. Hoffentlich nur ein Bug? ### 3/5 — Tutorial *2016-07-20, version 1.0* THis game is quite fun; however, the levels get very difficult quickly and the "hints" are not helpful at higher levels.....therefore, the other choice is to constantly buy coins to see how to even approach the maze. I suggest you have a tutorial with examples before each level. I have given up on the light show .. too kiddish and not in keeping with a Zen theme. Looks like a pinball machine. Are there other versions that are more to what I have described? And what is with the letters? these are nonsensical and boring to me. Either stay with a Zen theme or make a flashy video game. Obviously I enjoy some parts of this or I would not take this time to give you feedback. ### 4/5 — Fast top *2021-04-05* Super knifflige aber entspannte Rätsel. Kleiner Ärger : das Spiel bleibt im Hintergrund nicht offen, sondern muss jedesmal neu gestartet werden. Ansonsten wirklich herausragend gut ### 4/5 — Great game same old music *2017-12-30, version 1.01* Super fun game played all the series but for god’s sake can you please add new music or let me select my tunes -1 star for that. ### 4/5 — Maddeningly Inconsistent *2016-08-30, version 1.01* Many puzzles are easy. A few can be finished better than perfect. But a few are insanely complicated with dozens of possible solutions, only one of which is the perfect one. Most hidden items are easy (a few way too easy) while others are much harder than the puzzle. No where near as good as the first three. ### 4/5 — I made a mistake! *2016-07-16, version 1.0* I did not know how the game worked and I thought it crashed my device.I was wrong,it works fine.If my previous review can be deleted,please do so .Thank you ### 5/5 — Wunderbares Spiel *2026-08-11* Eine Herausforderung, die richtig viel Spaß macht. Man muss überlegt an die Lösung der einzelnen Aufgaben herangehen. Strategisches Vorgehen und räumliches Denken sind hier gefordert. Diese Spiel (und seine Ableger) sind wahre Perlen. ### 5/5 — This game has had such an impact on my life. *2025-11-09, version 1.03* I love this game with all my heart. The puzzles, the music, the letters, everything. I have cried to this game twice in a row. I find this game quite comforting and i will continue playing these games. In fact, i've had a couple dreams abt quell too. Thank you for the quell series, Fallen Tree Games, thank you so much. :) ### 5/5 — Best puzzle game ever *2024-09-22, version 1.03* Seriously the best. The puzzles, the game mechanics, even the tranquil soundtrack. I love everything about this game and the other Quell games. I wish they would make more. ### 5/5 — Wunderschönes Spiel *2024-02-03* Gerne mehr davon. Die Musik, die Töne und die Herausforderungen machen es wirklich zu einem guten Spiel. ## Most praised reviews (6 highest-rated) ### 5/5 — One of the best games! *2022-11-09, version 1.03* Wish there were more! The Zen edition had this intense Bplot with a story that progresses as you complete levels. It doesn’t resolve itself and it is a bit bonkers but very intriguing. ### 5/5 — Chilled puzzler *2022-09-09, version 1.03* Satisfying puzzles with a well timed scaling up of difficulty ### 5/5 — Love all quell! *2022-07-10, version 1.03* I love all the quell games, this one has a touching story and enough evolution to the puzzle formula to keep it fresh. I recommend you play all the quell games if you like this one. ### 5/5 — Amazing *2022-04-19, version 1.03* Best game ever. Even if i have completed all the levels i would redo them. This game brings back so many memories and hopefully we can see more types of games like this in the future. Thank you for making this game ### 5/5 — The Best *2022-02-24, version 1.03* I love these gorgeous puzzles and I appreciate the light narrative framing. Hope to see another entry someday! ### 5/5 — Il migliore di sempre *2022-01-08, version 1.03* Il migliore di sempre --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
