1. 01

   u = the first 52 bits of the byte stream, from your own seed pair like a dice roll.

2. 02

   Win iff u < floor(2^52 × 9,500 ÷ (multiplier × 10,000)). The chance is rounded down, never up.

3. 03

   Payout = stake × multiplier, where the stake is what the prizes you staked were held at.

4. 04

   The prize a win arrives as: the most valuable prize of the catalogue worth no more than the payout; among prizes of the same value, the catalogue's first. The rest of the payout is balance.

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

Choose one or more prizes from your inventory and a multiplier from 1.01× to 9,500×. The chance of winning is 95% ÷ the multiplier: 47.5% at 2×, 9.5% at 10×, 0.01% at 9,500×.

Lose, and the prizes you staked are gone. Win, and you are paid what they were held at × the multiplier.

A win arrives as the most valuable prize in the catalogue that fits inside the amount, and the rest of the amount is paid to your balance: nothing of it is lost. The page shows that prize and the rest before you confirm.

Every multiplier returns 95% of what is staked, on average. The other 5% is the house's.

A prize is held at an amount of the coin it was won in. It can be sold for exactly that amount at any time, with no fee, also during a break or an exclusion: selling is not a bet. Nothing is shipped.

An upgrade that could pay more than the site's ordinary $250,000 maximum, up to $10,000,000, is taken with a real coin only while the house's own funds would pay it in full, in that coin; otherwise it says so and takes nothing. Play credits can always take it.
