Actually, I have tried all the method whatever those Matginale or my calculated ones or whatsoever, the chance to lose is WAY bigger than to win:-
Why?
#1. The NPC got unlimited money, and whether you are a billionare, or super billianare in UO, giving out 1 mil would hurt yourself, because human is just that greedy.
#2. The dice are rolled randomly by UO, unless there are more people playing the game at the same time, otherwise there is always way that the NPC cheat you by not opening your numbers. (Guess what I have tried not winning for 40 streaks [outside bet] for 1 v 1 with the NPC). What a scam!!!
#3. 100, 200, 400, 800, 1600, 3200, 6400 is purely stupid and crazy because in UO, it is easy to lose 7 streaks in a row. Unless like i said, you have 10 others people sitting besides you, losing the bets to the NPC (well you see, the NPC still gains).
#4. I tried to bet for 1 single number for approximately 10 times (on the guess dice game), those 10 times streak never opened my number.
#5. I then tried to randomly pick the number every time and increase my bet everytime I lose, still 10 or 20 times streak, the game just wouldnt open my number (maybe I am just that unlucky), but I doubt it. I think its just the UO setting making the system not rolling that dice. (well maybe I am wrong, but I have a strong feeling that is it) Because as stated by many others of the above, in reality, the chance to lose 7 times streak is very low %, but to me, it isnt a very low %, just now i just changed 5000 chips and do a simple test, I basically using the Martingale strategy and lost 20 streaks in a row immediately and all my 500k gold is gone.
So in conclusion, this UO casino is actually a gold sink to me for now rather than a place to dupe money. So my advice is, if you are to play this game, just set your target first.
How much you wanna lose today?
5 mil? 10 mil? 50 mil? Once its all lost, then just quit your game for today.
If you're in a winning streak (which is very unlikely) because the odds for winning even the highest chance per game is approximately max of 30%, then continue your winning streaks until you have reached a losing streak of 6 times then you just quit and call it a day and get what you earned.
Don't play for the Matingale method as everytime earn 10k is really crappy!
Try set a target like this:-
2,000 chips
5,000 chips
10,000 chips
if 2,000 wins = next round 4,000 chips
if 4,000 wins = back to 2,000 chips [because rarely would be able to have more than 2 streaks; i have tried many times]
If 2,000 lose = next round 5,000 chips
if 5,000 lose = next round 10,000 chips
if 10,000 lose = back to 2,000 chips
if 2nd round 2,000 lose = next round 5,000 chips
if 2nd round 5,000 lose = next round 10,000 chips
if 2nd round 10,000 lose = just quit and call it a day or change another char to play if you are so addicted
if you are keep on winning 2,000, 4,000 or 2,000, 5,000 or 10,000 (which usually you wont get in a lose streak more than 3; just continue the same method until you reach a lose streak of 6 then just cash out and call it a day).
This would be the method I use in UO world.
The max you lose is 3.4 mil. Moreover, you're not using (100+200+400+800+1600+3200+6400) for 100 chips! LOL
100 chips = 10,000 = you need to win 340 times to win 3.4 mil -.-... this is not what UO peeps like to call RISK VS REWARD.. not worth it man.
So in conclusion Martingale strategy doesnt work for unlucky guys and its MORE stupid to work for lucky guys.
Because if you are lucky, you would just bet 10k chips and get it all the way to 100k chips... because if you are a lucky guy than the NPC, you would have win more than lose even in EVEN BETS.
But this is UO and the program are customized so that you have very low chance or probably (0%) chance to win in the end, so playing EVEN BETS and trying to win UO is probably never gonna happen.
I tried all of the game.
big
small
(except middle) <- cuz this one is stupidly low chance
outside <- this one i thought is good, but when I have seen ppl and myself lost over 40 streaks, it is hopeless.
guess dice <- i lost over 20 streaks in a row in a 1 v 1 so making me think that UO have programed so that it is possible the dice (whether same number or not), wont appear at all until your chips run out LOL.
Anyways, so long and maybe some are repetitives that I have posted.. but just my experience from these 3 days.
Now in conclusion:-
1st day - 3.5 mil net profit [using random bets from 1k to 10k and not Martingale or whatever method applied, just all randomly]
2nd day - 5 mil net loss [using all mixed method, Martingale, whatever 1/4/7, etc..]
3rd day - 3 mil net loss [using all mixed method, random dice]
