If you see a 'verification' page here's what you need to do to download your APP/GAME:
1. Select first FREE APP or OFFER and then FOLLOW INSTRUCTIONS! from selected APP / OFFER
I can advise you to select the easiest offers like 'Install and run for 30 seconds'. But if there's no such offers, please select another. Offers depends upon the country you live in.
I'll do offer 'Fetch Rewards', so I need to Install this app and then run the app for MORE than 30 seconds. After clicking on this app it'll redirect me to the App Store or Google Play.
2. Install Fetch Rewards and then run it for more than 30 seconds.
First offer done!
3. Select second FREE APP or OFFER and then FOLLOW INSTRUCTIONS! from selected APP / OFFER
I'll do offer 'Disney Heroes: Battle Mode', so I need to Install this game and then Reach Team Level 5. After clicking on this game it'll redirect me to the App Store or Google Play.
After installing this game I need to Reach Team Level 5.
4. DONE! About 1-2 min after reaching team level 5 my app is installed on my device!
Another tip for you - if for some reason installing two apps is not enough, try to make another offers.
