Case Jackpot

1. 01

   When a pot opens the house draws a seed and shows its SHA-256. The seed is published when the pot is paid.

2. 02

   The draw is the Jackpot's: tickets are the smallest units paid for the cases, in the order the entries were made; u = u52(0) of the stream with client seed "<pot id>:draw", nonce 0; the winning ticket is floor(u × pot ÷ 2⁵²).

3. 03

   Case k of the pot (k counts every case, in the order they were put in): the pull is the Cases derivation with server seed = the pot's seed, client seed = "<pot id>:case:<k>", nonce 0.

4. 04

   A pull is worth the price paid for its case × the prize's multiplier. The winner is paid the sum.

float(k) and the rest of the notation are defined in the byte stream.

One pot is open at a time. Put cases into it, up to ten at a time: each is bought at its price. What you paid for your cases is your share of the pot, and your share is your chance.

When a second player comes in, a clock of 120 seconds starts. It does not restart when somebody adds more. When it runs out the pot closes and one player is drawn, by share.

Every case in the pot is then opened for that player, each by its own printed odds, the cheapest cases first and ten at a time. The winner is paid what the cases gave: as prizes to keep, or to the balance if that is how their prizes are paid.

The house takes no share of the pot. Its edge is the cases' own: on average the cases give back about 96% of what was paid for them, and that is what a pot returns on average, whoever wins it.

While you are the only player and no clock is running, you can take your cases back for what you paid. If nobody else comes in for 30 minutes they are returned. Once a second player is in, they stay in the pot.

A pot holds at most 100 cases, 30 from one player. All of a pot's cases together must not be able to give more than the site's $250,000 maximum payout: an entry that would pass it is refused. A case with a prize above that maximum is not taken into a pot.
