This is what i do but I use T11 app on iphone instead of facebook for daily ads. Then i log in through browser on pc (firefox). There is a blue box on the right hand side that says 'WATCH VIEOS FOR FREE TOKENS'. I can get up to 20T a day from this in the UK. I would say my daily T averge from this is about 12-15. NO DOWNLOADING GAMES AND LEVELING UP B******T.
I have been doing this since i started. I assumed everyone else knew about it as you can't miss it but i'm not sure if it gave you that option in the old version which a lot of the more experienced players prefered.
