Overview
One pot, ninety seconds, one winner. Everybody buys in, one wallet takes the lot, and the house is not on the other side of it — we hold the money and take 5%.
There is no house edge here, and that is not a slogan
At blackjack or slots the house is your opponent and the edge is the price of playing. At jackpot the money in the pot is players' money, and all of it goes back out again: the winner is paid out of the pot we are already holding. So there is no edge to quote, and instead there is something stricter, because it is exact rather than statistical:
Your chance is your share
Entries buy tickets, and a ticket is one MIST — the smallest unit of SUI there is. So the ticket space is the pot, and your chance of winning is your stake divided by the pot, with nothing left over. Put in a quarter of the pot, win a quarter of the time.
Entries run from 1 SUI to 300 SUI, and you may enter more than once — a second entry simply adds to your share.
What it costs
The house takes 5% of the pot and nothing else. There is no rake on a losing entry, no fee on the draw and no spread: 95% of everything paid in is paid back out to one wallet, every round.
If too few people turn up
A pot that closes with fewer than two players is void. Every entry is refunded in full and no rake is taken. Charging 5% for a game that did not happen is not a rounding decision, and it does not happen.
