Voller Spam-Werbung

Das Spiel selbst ist in Ordnung. Aber man wird ständig mit betrügerischer Werbung für irgendwelche Fake-Wunderprodukte belästigt, die man auch nicht ordentlich melden kann. In den Privacy-Einstellungen kann man zwar ausschalten, dass Anbieter mit „berechtigtem Interesse“ Daten abgreifen können, aber die Einstellung lässt sich nicht speichern. Unklar, ob das Absicht oder schlechte Programmierung ist, in jedem Fall ist das nicht in Ordnung.

Very greedy

Recent changes

Loved this game because it only gave advertisements between games. I wouldn’t mind several (3?) between games. Now doing a killer it breaks away every couple of minutes while you are trying to think. I may continue to do the daily but am looking for a different app now.

Best I’ve tried

I’ve tried a few Killer Sudoku one and like this one the best. I liked the idea of the coloured one, but shaded squares looked like different colours. This one moves quickly with few ads and auto completion.

Excellent game, recently fewer adds?

Edit… I previously marked this low, despite being addicted to the killer game, due to frequent and lengthy adds… recently they seem less frequent and many are relatively quick, hence 4*

…..

This is the best of the killer sodoku’s, I’ve been playing it a few times day, but the adds are driving me nuts, some take a minute, some get stuck and the app has to be restarted… only to get a new add. I’m off to try other apps instead

Ps thanks for the reply, have an extra star, I still use it but not as much as I still hate the ads and it’s too expensive to buy
