We don't control the rewarding. We issue you credits when our partners (the offer providers) send us a notification to our system. Sometimes it does take a bit more time (up to 24 hours) before you get rewarded.
#1 Why you may not be credited
* If you have previously installed the app on your device, you will not be rewarded for it again. This is frequently the case if you are using other reward apps.
* You did not follow the offer requirement (the requirement is stated right on the offer)
* You haven't played with the app enough. Try to sign up for an account, advance a few levels, complete tutorial, etc (even if the offer states "Install and Play")
* It take anywhere from a few minutes up to 24 hours to verify your conversion.
* If you have a jailbroken/rooted phone - some advertisers may block conversions on jailbroken devices
* Do not reinstall the app. It almost never works (advertisers will block this)
* If you are downloading a lot of apps at once and playing with them sporadically (3 hours later, one day later, etc) the chances of getting rewarded will be significantly lower.
#2 To maximize the chances of getting credited
* Make sure you follow the offer requirement
* Make sure you play with the app enough (advance a few levels, play with basic functionality of the app, complete tutorial, sign up for an account, etc)
* Check out an app offer one at a time. Don't download a lot of apps at once. Open and play with the app immediately after installing the app.
