There is a new free game on Facebook called “Unlock Possibilities” from Huawei. What's interesting about this game is that it lets you win a Mercedes E-class Coupe (there are two of them). There are other prizes as well - Huawei Ascend P6 phone, vouchers, in-game points or E-Points.
The game is simple - first you have to like Huawei's facebook page, which gives you 1000 points. They are used to unlock boxes. You have 3 chances of spinning the side image, which, if it matches the one on the top, gives you points and then you have to invite Facebook friends.
Good luck to all!
