"Let's see how much YOU can earn "
Already tried to show my son that the ADnoyance for the scam apps are a bit exxagerating when it comes to the rewards.
I tried "mistplay" just because i believe the name is multilingually funny, as the scheme is rather foggy and "mist" is the german peasant word for manure.
Instead of the promised "get paid for playing your (!) games", theres a list of games you must install through that mistplay app, which redirects to playstore for installation. Games you had installed and are now re installing via mistplay only count for playtime rewards, not for installation.
If you want to earn the reward points, you must start the games via the mistplay app and must allow mistplay to display over other apps to track the time and game progress.
Of course you can get points faster when playing microtransaction games and "spending in loyalty apps" but i chose three "idle" games (basically inflated screensavers with the occasional clicking/tapping).
Then theres "events" much like the "tasks" mentioned in the article. Basically things like "play game X for XX minutes or "play any two games for xx minutes" or the aforementioned "spend any amount in loyalty games" which of course gives the most points.
If you dont spend but let the smartphone play the "idle games" while charging, it takes around half a year to accumulate enough points for a 5 euro voucher. (Currently priced at 1800 "units"). Of course the addiction mechanics are there, meaningless player points to let you "augment" your profile/avatar, meaningless "honorary titles" that activate for each game when playing a certain amount of time or one hour after 22:00 or similar "achievements". Theres also a "x day streak", just a number of consecutive logins. As every "streak" gives 2 "units" and this amount does not increase at all, i believe they missed an addiction factor since it makes no difference if you are a true believer or take a week off.
So how did it pay out ? First you must register via camera "to prove that you are a human". As that somewhat triggers my paranoia, i decided to show the plastic head that my wife is using for manufacturing renaissance and klingon mask/wig combinations. According to that software, it is now a human. Then you can select vouchers. Google play, amazon, the like. After around 2 workdays you get an email with a link to the voucher code.
With every payout, the reward for "simply playing" is reduced as the "game checkpoints" are harder and harder to reach, theres no more rewards after checkpoint 20 and the "checkpoint" rewards decrease the higher you get.
The tasks/"events" pay as much as 15 "units" as a maximum ( minimum is 5 "units" and thats the majority of tasks/"events") while the "spending in loyalty apps" is announced at 50 "units".
The old phone that was abused for this scam test is still lying around and every once in a while, i take a look at "mistplay" just to check if they implement one of the other usual scams - automatically reducing your account or deactivating it due to inactivity, effectively stealing "your" "units".
TL:DR as many would have assumed, the "rewards" are somewhat unrewarding for all the hassle one has to go through and all the time and energy spent.
