LitterLotto
LitterLotto is a free to enter Prize Draw, with regular spot prizes and huge jackpots, supported by brands who want a cleaner environment.
To enter, simply use the app to take a picture of litter as you place it in a bin. Each time you submit a new piece of litter it's another chance to win!
LitterLotto is available globally, with different Jackpot levels wherever you are!
I have so far got an instant spot prize 3 times of £5 each time. There is an iPhone or an Android app. Just a quick photo as you pop rubbish in the bin while out and about for the chance.
