Aggressive ad load

Review signal, not a finding

207 reviews · 28.0% of reviews scanned

an ad before you play every level, half the time I have watched the same ad several times before being able to play. too many ads, i know it pays for the game, but when you have to watch the same ad 4 or more times just to play a level…

1★ · Google Play · 2026-10-10

the game itself is fun. the amount of ads is ridiculous. It is one to 3 minutes ads for ever level or two. If you get to higher levels the apps has more ad time then playing time.

2★ · Google Play · 2026-10-14

I downloaded this via a different puzzle. The blurb said 'no ads'. I get ads - long ones- every 2 games!

No ad complaints

Review signal, not a finding

45 reviews · 6.1% of reviews scanned

Not ad free like advertised. This app is just like similar ones, ads in all.

3★ · Google Play · 2026-10-15

came from an ad in another game, which claimed this game has no ads. game is genuily entertaining but after level 35, there is an ad at the end of each level feeling deceived and i thought finally a game i could recommend to a friend…

3★ · Google Play · 2026-10-14

it says no ads but, but not true. Also, its gives you a daily leaderborard against "other" players. In reality, they are bots. You can be ahead hundred of points and then suddenly after a game you are in fifth place. Its impossible, the…

Misleading advertising

Review signal, not a finding

42 reviews · 5.7% of reviews scanned

Fun game, no ads until a few levels insomnia blatant false advertising.

1★ · Google Play · 2026-10-14

Blatant false advertising. Every video and Ad you see for this game says "No Ads", which it definitely does have and the further you get, the more frequent they become. Mobile games should be held accountable for advertising like…

1★ · Google Play · 2026-10-13

Game was advertised as ad free but after level 50 ads start playing. That is not ok, lying to the players. If you advertised as with ads and added a paying remove add option, then i would be ok with it.

1★ · Google Play · 2026-10-12

A sampled review illustrates one person’s experience. It does not establish a finding on its own.

Measurements

5 measured · 3 not assessed

Supporting measurements. They are not a complete list of possible harms or positives. “Not assessed” means we could not measure it — never zero, never a pass.

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.

Method and limits

What this report can and cannot show

How a review signal works

A review signal is produced automatically from public app reviews by a classifier — never by a hands-on Appworthy test, and never by a human analyst. It exists so a real, not-yet-audited app can carry more than a blank “Not yet tested” listing, without ever being mistaken for an assessment.

A theme only appears above once at least 5 distinct reviews corroborate it — one angry review can never tag an app. These thresholds are published settings and may be tuned as coverage grows.

It carries no confirmed findings — reviews are one kind of evidence, and nothing here has been hands-on tested. The moment Appworthy publishes a full assessment of this app, it replaces this signal, permanently.

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 replaces this review-derived signal with hands-on, recorded measurements. Hands-on inspections are not yet open.
