I will admit, I have been using the glitch to increase my wealth. Atleast for one of my characters anyways. Supposedly theres a rumor that the glitch was intentional so that when you merge your characters together, they will be automatically aligned as "evil". But I guess well have to wait until october to see.
As for keystone, I have had little luck with it. Ive been trying out several methods listed below, but even those seem to have little luck.
1) High stakes/ Low probability: The best way to make gold on Keystone is to max out your bets on the 3 and 18 arches, then max your bets on the inside bottom row (the Trips and 18 and 3). The probability of you landing on any of these is low, therefore when you win, you'll make much more than you've bet.
2) Lower stakes/ High probability: The best way to do this is to place the max bet on the 10 and 11 arches only, and then place the max bet on the 4-9 and the 12-17 squares. If you'd like to, you can also place max bets on the odds/evens and the red/black squares. This method results in you making money almost every time, and you will win more than you lose.
3) The Jackpot: For this, you must play either the Jackpot Keystones, or any one of the tournaments. When betting, place the max bet on any one of the arches, but none of the inside squares. If the number you roll is not a 3 or an 18, quit the current game and try again. Repeat this method until you roll 3 or 18 and get the jackpot. *just aside note here, these are not my ideas...just something I got from other forums I visit.
One other method is to bet minimum on one arch (preferabbly keystone) then just sit the rest of the game doing nothing. Ive tried all these methods several times with the High stakes/Low probablity giving me the most success (about 35% chance of placing in tournaments, havent tried it outside of that).
