Final Fantasy X Hints & Cheats

After you've defeated Yunalesca at the Yevon Dome in Zanarkand and aqquired the airship, search for these locations by using the X and Y coordinates:

You must have all aeons and the Celestial Mirror. Then deafeat all of Belgimene's Aeons

Valefor also has a second Overdirve that you can acquire once Yuna join the party. Return to Besaid and speak to the little girl with a dog standing next to the temple, and you'll receive an item that gives Valefor the Overdrive Energy Blast. If the little girl isn't near the temple, then look for her inside the item shop. Energy Blast inflicts greater damage at the cost of a higher recovery time.

There are also hidden locations accessible by using the "Input" feature found in the airship command list. You can find these passwords by deciphering Al Bhed messages left in specific locations around Spira. Note that all of the passwords are case-sensitive.

After you get the Airship go back to Guadosalam. Follow Tromell up to the Farplane. Talk with Lulu to view the secret scene.

During a blitzball game, go to one of the corners on the right side of the arena, also referred to as the easy win bug. While there, put the two players that you want to gain experience side by side, and have them pass the ball repeatedly to each other. Each pass gives you 1 EXP, and if there's at least two minutes on the clock, you can accumulate up to 30 EXP.

When you fight Evrae Atlana underwater in Bevelle, simply use some Phoenix Downs on her and she should die quickly. If you don't have any Phoenix Downs, X-Potions and Elixers work wonders against her as well.

When you find Yojimbo, wait for him to make his offer. After he makes the offer, which I believe is 300,000 gil, offer him half of what he wants plus 1 gil. He will then lower his asking price. Increase your offer by 1 gil, which will force him to lower it again. This time, he will not take any amount much lower, so offer him about 5-10,000 gil less than what he wants, generally around 190,000, and he should take it.
If not, repeat the process and simply offer a little more than your previous offer.

If you offer him TRIPLE what he wants at any time, you not only gain Yojimbo, but he gives you 2 Teleport Spheres as well.

Whenever you are playing Blitzball, and currently are winning (i.e. your score is higher than the other team's) just swim behind your own goalie. Stay there and everyone else on the field will go to the other side and swim in circles. Sometimes, a member of the opposite team will follow you. Just shake him loose (breaking through him is an easy way) and he too will just leave you alone. Stay there for the remainder of the game and you will win.

When bribing a monster it sometimes misses.Then you have to bribe again and waste money.Well, if it misses, you can bribe them again for 0.This will actually count as bribing again.This is a good way of saving money bribing without having to reset, especially if the monster takes over 1,000,000 gil to bribe.

Use Provoke on him. As long as you don't switch out the character who used Provoke (this includes by summoning), Defender X will only attack them and no one else, and only with Blast Punch, which cannot kill you, making it impossible to lose.
