The locked cubes are not moveable and they will be your guide. It seems that it is a piece of cake, right? Well, the beginning levels are really easy to pass, but on the other hand, when the number of locked cubes and the number of colorful cubes increase, the game becomes more interesting and challenging.  377 levels will challenge your logic and sense of color. ## Key features - Harmonious cube placement - Gradient-based puzzles - Locked cube guides - 377 challenging levels - Logic and color testing ## Recent user reviews (5 of 5) All indexed reviews: https://appshunter.io/ios/app/hue/id1567355347/reviews.md ### 4/5 — I couldn’t even get one *2025-12-25* Maybe I should see an optometrist. But I can’t see any difference - and the puzzles start with one locked square, so no ability to even try anything differently. It’s a good idea tho. I wish there were other color modes for color blind-like. ### 1/5 — Doesn’t start *2022-06-30* I have an IPhone 13 mini and the game is not opening. It closes before it even starts… **Developer response:** Hm, that is very strange. I will check, what is wrong. Thank you for your reply. Please, write me a letter: trembach.artem@gmail.com ### 1/5 — Не работает приложение *2022-04-23* Приложение даже не открывается **Developer response:** Впервые слышу о такой проблеме, давайте ее решим! Пожалуйста, напишите мне на почту: trembach.artem@gmail.com ### 5/5 — Милота 🥰 *2021-08-05* Обалденная игра по цене бутылки воды 🤩 **Developer response:** Спасибо 😇 ### 4/5 — Can’t listen to podcast while playing *2021-07-29* I prefer listening to my own music or a podcast while playing these types of games. Can’t play own audio - auto-uninstall. **Developer response:** We fixed this issue, please, update game and enjoy! Thank you for comment! :) ## Frequently asked questions about HUE² ### What is HUE²?
