About this app
Nominated for Best Mobile Game at German Computer Games Award 2018.
„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 guide the cube QB through a stylistic, rudimentary world. On his journey, QB is faced with great challenges. Various other cubes obstruct his way to the coveted black cube, which will bring him closer to his goal.
PRESENTATION
QB - a cube's tale is an isometric puzzler that manages to challenge you with very few elements. Each puzzle is hand-crafted and captivates with a very clear, miraculously minimalistic graphic in isometric 3D.
CONTROLS
The controls are as simple as minimal. By simply swiping, you move QB one step in the direction indicated. If you rest your finger on the screen QB moves in the same direction until you lift your finger again.…

Themes reported by reviewers
No theme reported
Counted from the reviews we have read for this app. "No theme reported" means no theme reached our reporting threshold — it is not a finding that nothing is wrong with this app, and we do not say it is.
Five-star share of ratings
65–79% five-star
Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.
In the app package we scanned
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence, not a finding.

Method and limits
What a missing label means
Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
Limits of this report
- A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
- Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
- Not assessed is a state. It is never a zero and never a pass.
- A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A human review gives an app hands-on, recorded measurements. None has been run for this app. Hands-on inspections are not yet open.
