The probability of the lower numbers are higher, especially the 1s. But the rare numbers do offer higher reward rates.
If you got enough money, my strategy goes like this:
Bet 1 - 100(min bet) -> success -> continue
-> fail -> Bet 1 - 200 -> success -> reset bet
-> fail -> Bet 1 - 600 -> success -> reset bet
-> fail -> Bet 1 - 1800
So you get the idea?
Bet 100 on 1 first, if fail bet 200 on 1 again. If you win, you will win 100 which cover your earlier loss.
Basically just go 100, if fail go 200, if fail go 600, if fail go 1800. Always reset your bet to min 100 when you win a round. Too bad the max bid is fixed at 5k, so if you miss getting a 1 in 4 straight rolls, time to go pack up and go to sleep.
PS. Dun blame me if my strategy dun work. Have fun and hope you manage to earn some gold. Any1 else with a better strategy can share pls.
