What we measured

Each line is a measurement published as a measurement, never a verdict.

How these are measured

Each line is a measurement, published as a measurement. Where we have not looked, the line says so rather than reading as a zero.

Themes reported by reviewers
1 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
80–89% five-star
Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.

In the 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 about the app, not a finding about it.

What the analysis found

App-specific findings, grouped by what each one rests on. How they are graded lives on its own page.

Methodology

One source only — shown, not confirmed 1

A single kind of evidence. We publish these because withholding them would be the bigger distortion, and we do not treat any of them as a finding we stand behind.

Reported by users: Aggressive ad load
One source onlyShown, not confirmed — the only source is user reviews.view evidence
Advertising volume or placement that interrupts normal use: ads between every action, unskippable or forced full-screen ads.
What we saw: Aggressive ad load: raised by 34 distinct reviewers (7.7% of 443 reviews scanned)

Highlighted reviews

Representative public review excerpts shown as user reports, not Appworthy audit evidence.

“I love the game. and I understand ad revenue. but ad after every sublevel and main level is just dumb. and having the choice between either paying for it or suffering through it just seems like pointless. I play this game to relax because…”

“The ads are insane. The puzzles are a few seconds but you will encounter two or three adds while you try to solve them. This game is completely unplayable.”
