Once you enroll, you will enter into a tribe with other contestants, you need to do challenges and vote off other members from your tribe, survivors for both tribes will merge and start another game.
Every day, each tribe will have daily challenges. A Challenge may consist in a small games like Endurance or based on TV games Wheel of Fortune or music challenges based on Guitar Hero, etc. The better your score is, the more time you will have to do your challenge. The tribe with less points won in the challenges will be the loosing tribe.
As it happens in the Survivor Game, the tribe with less points will start the elimination process, all tribe members will have to vote, the game will automatically eliminate the tribe member with less votes.
Once the 2 tribes have 10 participants only, the participants not previously evicted from both tribes will be merge and form one new tribe. This tribe will start a new game against another newly formed tribe or another recently merged tribe.
All tribes and games are created automatically, you just need to enroll and you will automatically be asigned to a tribe. Once the tribe is ready the Survivor game will start.
It's not exactly the same as CBS survivor, first you can play in your home and don't need to go to an island :), but we have some similarities with the Survivor show.
