Hints
Spinnerbox: Faster game
While playing a game of Spinnerbox, press A to stop the spinners quicker. It does not change your chances of winning.
Keystone tournament: Easy wins
Use the following trick if you become stuck on one of the Keystone tournaments. Check the scores after you finish the first game of five. Check if one of the top five scoring players are at your table (press RT to see the game standings). If so, copy the bets of that player. Chances are his luck will continue and you will gradually work your way to the top. You can play it safe and not bet on the long shots such as a trip, three 2's rolled, three 3's, etc. when the player bets on them.

Start a Tournament game of Keystones. Place the maximum bets on the outer arch. Roll the dice until the game finishes, making sure not to place any other inside bets or the results may be flawed and you can lose. Using this trick will double your placed bets and ensure that you will stay in one of the top places, earning you the desired item. Because the CPU keeps betting on the inside bets, it will keep losing its gold, allowing you keep placing to the top. It is possible to win the entire tournament just by doing this trick.
Easy money
Start a game of Keystones. Place your arch bet on 7, 8, 9, 12, 13, or 14. Press X. Do not place any inside bets. Press X until your arch stone is rolled. Collect your money and repeat. Note: Although slow, it is a reliable way to gain money.
Glitches
Fortunes Tower: Wrong bet amount
Play Fortune's Tower on 150 to 1500. Select 150 gold as your bet. After the gate card is laid down, press LB to increase your bet to the maximum value of 1,500 gold. The amount of money you will be at risk of losing will still be 150 gold, however if you win it will be as if you had bet 1,500 gold.
But they are worth playing because the loot you aquire is applied to your Fable 2 Charactor... More games should use mechanics like that...
