100 numbered slots, counting down to one.
$1 takes the next one and puts your name on the homepage.
1Claim a slot for $1. The board locks on you for a minute, then you stay up until somebody else claims.
2Take slot 1 and you are the Kingpin. The whole homepage is yours for 48 hours.
3Anyone can pay $200 to dethrone you and inherit the time you had left. The price doubles every time it changes hands.
4When the reign ends the round freezes into the Record, permanently, and a new board opens at 100.
No accounts. No signup. Land, see the number, take it.
