A revival of a great series.

I have already played and thoroughly enjoyed the first three Quell games. After an interval of some time, this fourth instalment has been released and features a new visual style and a new backstory, but the experience is familiar and it is still wonderful to play. The price is higher than the previous Quell games, but with enough levels for hours of gameplay, engaging challenges and a serene atmosphere, it's still good value. With so many junk apps and frenzied battle games on the App Store these days, a gorgeous and relaxing puzzle classic like Quell Zen certainly makes a nice change.

Top class


The Quell series games have all been a beautiful and immersive way to spend a rainy day. The theme this time is letters to a loved one lost.



The best puzzle game out there. Hours of fun
