To buy Chip Tricks, go to Store (X Button if in-game), and move down to Chip Tricks.
The minimum level you will have to be to buy 4 Chip Tricks is Level 8. On Level 8, you will have to spend 12,400 Chips and 4 Gold to get 4 Chip Tricks.
If you'd rather not spend the 5 Gold you get for free by starting the game, then you'll have to wait until Level 10. On Level 10, you will have to spend 18,500 Chips to get 4 Chip Tricks.
The first 5 Chip Tricks are:
Shuffle
The Knuckler
Flipper (costs 4 Gold)
Finger Flip
Gyro
Once that's done, you'll have to use at least four, 1 at the Pre-Flop, a different one after the Flop, a different one after the Turn, and your last of the four after the River.
After all this, you have to win the hand and/or a showdown if other players are still in.
Just keep doing all four Tricks at all four opportunities that you get, and if you have any skill or luck on your side, you'll eventually win.
