*this is similar to TAREKEGYPT's post, but it does have some differences.
ok... the keystone tournaments definitely gave me the biggest problem on this game. and I have a sure fire way to get this achievement if you are having problems getting it due to the keystone tournaments.
heres what I did for the keystone tournaments:
when first starting MAX BET on ALL archstones 3 - 18. then when you get to the inside bets, MAX bet on the ENTIRE bottom row which is 3, 3 of kind (2s), 3 of a kind (3s), TRIPS, 3 of a kind (4s), 3 of a kind (5s), and 18.
Now roll.
if you dont get trips or a jackpot on the first roll, then do all the same inside bets as before and roll again. keep doing this until you get trips. or until you run out of money. if that happens just cash out and exit game and then start the tournament over.
when you get trips (3 of a kind) you are going to get a payout for betting on TRIPS, for betting on whatever 3 of a kind you got, and also for the archstone that you bet on that the 3 of a kind equalled. this 9 times out of 10 will put you at more than double the score of the #2 guy.
for the rest of the tournament dont make anymore inside bets!!!! only make a minimum bet on 1 archstone to get the game going. you could max bet on the archstones still, but it is not recommended because if the 3, both the 10 and 11,or 18 is removed you will lose quit a bit of gold, which you dont want! at this point you are so far ahead that the only thing that would knock you out of first place is if the computer scored a jackpot and 4 or 5 trips but im pretty sure that no one would have luck that bad. if in some crazy way you do happen to get a few bad rolls where the computer gets alot, you should atleast be far enough ahead in the beginning that you will atleast finish in the top 5.
I sat here tonight playing this game for 2 hours trying to beat these tournaments using other peoples methods, then I tried this and beat all tournaments in 20 minutes.
As for the spinnerbox tournaments there is no real strategy. you have no control over how much you bet, and you have no way of altering your spins. you just have to get lucky.
Fortunes Tower really isn't that difficult. Just watch the tutorial, and play fortunes tower enough to get the hang of it and to know what you are doing and you should be fine.
