Here's how it works
You will post "Prep #" In seperate posts
Example: Prep 1
Prep 2
For every prep you have, you gain a "YES" in a random.org list with 20 NO'S.
You can try to prep as fast as you can.
When someone wants to light a match, they post "LIGHT" at that point you both have to stop and wait until I say if it lights or not. I'll randomize their list and see if it's a YES or a NO. If it's a no, then nothing happens, I'll post it was a no and you can resume as you would like. If it's a yes, then I'll randomize your prep list again, adding 8 more YES's, and if you get a YES, you win. If you get a NO at that point, you have to continue doing the normal thing (prepping if you want and trying to light when you see fit) but you will lose 4 of your YES'S if your fire starts and then goes out.
This isn't turn-based, you have to prep as fast as you can, but remember to stop when someone tries to light because that's dependent on my speed and that should be a constant.
