This is my chance spinner that I did it at Qrafter.
1. We have to scan the barcode
2.Then go to URL
3. Set the line to the place you want
4.Press the "spin"button,if you don't want to wait until it finished,you can tap on the "skip to end" button.
5.Go to the app "Pic Collage"
(The chances are impossible,unlikely,equal or even chance,likely and certain.)
