Fable II Pub Games

A little trick:

Enter one of the free-to-enter tournaments, so you won't be wasting any real money. Just keep playing Fortune's Tower until you get it right. To get a jackpot, you need to reach the bottom row without using your gate card at the top.

To earn a jackpot in Fortune's Tower, you must reach the final layer of cards without using your Gate Card.

Unfortunately, there is no trick to this. However, I suggest that you try to win as much money as possible before trying this as you may lose several thousand gold in the process. Start a Fortune's Tower game with a low minimum bid and keep hitting the A button until you win a jackpot.

Fortune's Tower is played with cards. A face down card called the Gate card is set down, which is a safety card in case you need to use it. Cards are lain down in the form of a pyramid until you get to the 8th row. If you make it to the 8th row without using your Gate card, you win the Jackpot. Hindering your advancement will be the fact that if 2 cards are laid vertically from each other, the game is over. The only hope you have would be to have also laid a hero card in that row, which will save you, or by using up your Gate card to take the place of the destroyed card, but that negates the jackpot.

In the tournaments menu, there is a free Fortune's Tower tournament that you can play, so this is a good place to work for the jackpot, as there is no risk of losing any gold.

Here are some tips for general play in Fortune's Tower, not just hunting the jackpot:

If you are past the third line (3 cards) and have already used your "gateway" card, take 10 or more. It's a loss, but you're already in a sticky spot.
Generally continue down until you DO use your gateway card. Odds are against getting 2+ losses in a single row. Sure, it happens... a lot, but odds are against it.
Anytime you hit 20+, you should probably take the deal. It's guaranteed earning.
The above apply differently in tournament play as follows:
Use a 1/3 to 1/2 full bet. Staying minimum is too safe, going max is too risky.
Try to always break even, at least, in every hand. Keep the first two tips above in mind though and weigh your risk carefully.
You can get away with playing conservatively in a single-player game, but in tournament play, you really can't. Push for it. If you are getting REALLY behind (50% of the next lowest player), start maxing out and taking risks. It's the ONLY way to catch back up
There is also a glitch that has been found in Fortune's Tower, allowing you to make more gold, much faster. Start your game with the lowest possible wager. Then press A to start the game but immediately hit LB which causes you to only pay the lowest bet, but the earnings correspond to the highest bet.

Very Simple but based on luck

All you have to do is go to tournament and choose the one that is free which you wont lose any gold at all. Keep pressing a and hope for the best as long as the card facing down doesnt get flipped. keep mashing the a button and you should get the achievment after the 8th row with the gate card (faced down card) is not flipped over.

This achievement requires you to reach the last row of cards in a hand of Spinnerbox without using the Gate Card(the turned over card at the top of the pyramid), so just keep playing a hand until you reach the last row and hope for the best. In order to do this you have to be lucky in been able to reach the end without getting two of the same value on cards near each other or use a Hero Card(a card with a picture of a knight on it) to save that row from failure with turns up randomly and is used on the row it turns up in, if necessary. As it goes by the basis of luck, it may take a while to unlock or you may be lucky and unlock it without trying.
