What if you had to pick something, like a number, if it rolls in then you win? Back as many numbers as you like but it costs ya (or limit it to one per person I have no preference), then have a roll over, like the real lottery?!
Say like, pick a number 1-100
If everyone backs the same number, split it, if its not won, roll it, winner takes all, maybe link it to the exchange rate takings so in Perma you win a shed load, get people hooked?! Heh heh, thus $'X'k jackpot+ but of metal or energy
If you have to pick a number it makes each player work for it, as it's a bit too random?
(I have never won the lottery - I figure I need to pick my own number!!!
