All you have to do is post your ZODIAC sign. The person coming after you posts his/her sign. And so on and so forth.
The fun is when we get three identical signs in a row. Well, those three become the winners. Let's say that the first person is a Aries, and the next too is a Aries. Now the third one has to be a Aries for them to become winners, unless of course, a Libra or Cancer or any other sign breaks their chain.
A simple rule is that the same user cannot post twice in the same group and that the winning group should not have more than three in number.
Got it? Letz Play!
