„I live and breathe for these brilliantly hand-crafted puzzle games that respect the player’s intelligence and time.“ – AppUnwrapper


In QB - a cube's tale, you roll through a total of 80 levels to reach each of the final black cubes. Over the course of the game, new cubes are introduced, each with their own mechanic, which make your journey more difficult. The trick of these colored cubes is: It depends on which direction you enter them. For example, one destroys the field in which you are moving. And before you know it, the goal is unattainable and the level starts again.

But do not worry, you can play each level as many times as you like. For example, to find the perfect way, because then up to 3 stars are waiting for you as a reward. With the collected stars new levels are unlocked. So you can skip a level if you have been particularly successful in another. If you have collected at least 190 stars, it gets tricky:

Because then you can enter the "Challenge Mode", where you have to solve a number of levels with just a single attempt. Here, your skills in 4 stages with 4 levels of difficulty will be put to the test.
Of course, your progress will be saved in the iCloud so you can continue playing on all your devices.

• Labyrinth puzzle in isometric 3D
• innovative, direction-dependent gameplay
• more than 10 colored cubes with individual mechanics
• 80 levels that can be unlocked via collected stars
• Challenge Mode
• iCloud synchronization

QB - a cube's tale is only compatible with devices that have iOS 9 or higher.

An Excellent Puzzle

This game gave me days of innocent pleasure, and perhaps honed my powers of memory and logical reasoning. It is just frustrating enough. Some levels we’re really tough for me, but I got through the, all. I may work through it again, trying to find the best possible routes and earn the three stars that come easily at first and only with difficulty later on. Really, an excellent diversion!

Lean, mean goodness

This is a clean, polished, sneakily-fiendish little game with tons of levels. No fat here. Just great puzzles.
It ramps up the challenge in very a subtle way with each additional mechanic, but it’s always a clever combination of complications and intuitive minimalism.
Pure and almost perfect.

Thank you! :)

Interesting concept but awful gameplay mechanics

This game seems to be the bad result of what happens when you don’t program something natively. I am very disappointed in the reviewers who said there was no lag and the gameplay was smooth. This couldn’t be further from reality.

I challenge someone to compare how unresponsive the cube movement is in the game as opposed to the absolutely buttery fluidity of something like Monument Valley.

I am constantly having to swipe in the same direction multiple times to move one space in this game and I am running this on the absolute top of the line (at the time of writing this review in April 2018) iPhone X!

I would love to play Lee of this game but instead of being fun and relaxing, it is frustrating.

Developer Response ,

Thanks for your feedback. I am sorry that you have had such bad experiences. If you like, feel free to send me an email and explain in more detail, what bothers you about the controls, because I hear this problem for the first time. That would help me. Thanks.
