Raffle is basicly a game that will have some slots ( numbers ) for people to choose and join, in between these numbers, one of them will come out using random.org [www.random.org] website and which gives a random number and who ever was the owner of that number will get the prize for free.

Non- Free Raffles:
Non-Free raffles will always have limited slots and the ending time for raffle will be mentioned, normally raffle ends when all the slots sold. people who want to join need to pay the price stated and then they can enter. The chance of winning in these raffles are higher.

Giveaways:
In Giveaways, people can join and there is no payment required, so people can join without any payment. There are usually things that you have to do before entering (Inviting friends, etc).

(for guys who still dont know/understand what this is; it is just simply a lucky draw where yous buy a ticket/slot number, and get a chance to win gangsta prizes)
