Sounds great Every Topic. I have run a few Survivors myself over a couple of years now between some friends. Her are the rules we play under, and have found to be very competitive. Take the golden thread out of these if you wish to create your own deal, or copy, it's up to you... Cheers...

The concept behind the Survivor Series is to choose winning selections. This is important as heavy penalties occur for selection errors. The object of this game is to Survive by collecting as many Lives as you can, so you can have a buffer to cover yourself for the inevitable placed selection, or worse, an unplaced selection. You start the game with 4 Lives, and hope by the end of 3 months you have lives remaining. Once you lose all your lives, you are eliminated from the game. At the end of the (you decide) month period, the player with the highest total lives in their kitty will be declared the winner, and take Crown as the King or Queen of Survivor.

RULES:

This event will run for (You decide) months.
Your selections must be recorded prior to the jump of the first race (R1) on that particular meeting.
Only Official NSW Tote results and dividends will be used.
Upon joining this competition, each player will receive 4 lives.
A winning selection will receive 1 Life.
A placed selection will lose 1 Life.
An unplaced selection will lose 2 Lives.
8 Selections are required each month.
These selections must be on a Saturday, Metropolitan meeting at either Sydney, Melbourne, Brisbane, Gold Coast(accepted as Metro), Adelaide, or Perth.
Each selection not placed will be treated as an unplaced selection, and therefore lose 2 Lives.
If a selection is scratched, no default will occur, providing there are still Saturdays left to select in the month. A scratching on the last Saturday of the month, will default to the highest weighted horse that starts that particular race.
Only after the completion of your 8 selections for the month will you be deemed to have survived or eliminated.
A winner will be declared only after the completion of all players 8 selections for the month.
In the event of a tie, the Crown will be split between the joint winners.
If you are eliminated, the game is ended until the start of the next competition.
If a winner is not found, the Crown will jackpot to the next Series.
