Final Stage(Armor Men): On the final stage, Voldemort will awaken 4 armors (2 at a time). After you kill those 4, a big one will come after you and he will shoot red rings that will kill you. If you hold your wand up (X button) it will keep you from getting killed/hurt by the red rings.
Alternate Ending Sequence: Collect all 17 Famous Witches and Wizards card to view an alternate ending.
Sloth Brain: The Sloth Brain is located in a hidden part of the forest.
Troll Trouble At The End: After you defeat the Devil's snare, catching the key, and defeating the giant chess game, you run into the Troll again. Best way to beat it is to use your spell Vengarden Leviosi to move all the objects out of the Troll's way and then he falls into a big hole and then your off to fight Lord Voldemort or so called Professor Qurriell.
Wizard Card: When 1st talking to the Weasley's in front of the Fat Lady, go to the left and hit Square, the bookcase should open and you should be able to get a Famous Withces and Wizards card.
Make Harry Sneeze: To make Harry sneeze, hold down Circle and press Triangle right after throwing a puff-a-pod any where in the game there are puff-a-pods. Note: Puff-a-pods can also make trolls sneeze!
To Get Extra Points: If you play the Quidditch Flaying Practice Area, you will race against another seeker and gain house points. Every match will tell you whether you have bronze/silver/gold medal. If you play and you get silver/bronze medal, you can try again to earn more house points.
To Play Extra Quidditch: If you play the Quidditch first time(GRYFFINDOR VS HUFFLEPUFF/RAVENCLAW), after you finished the first match, save your game. If you load your game, it will say something like play quidditch or continued game. When you play the Quidditch, you have to play one by one.
Secret Bookcases: When you find a bookcase you can't climb, stand next to it and press square. The bookcase will open and you will go in.
The Chess Game: The goal is to get rid of all of the pieces. To do this, you need to get two pieces to go to the same space. When one attacks, the attacked piece and its attacker both die. If you go in a space right next to a piece, you lose some life and have to start that board over. Here are the hints on how to get through the 3 boards. Board one: Start on the left square: go right, diagonal(up+left), down Board two: Start on the left square: go up, diagonal(down+right), left Board three: This may not work (worked for me!) but try it anyway: Start on the left: go diagonal (up+left), diagonal(up+left), left, right, down.
Bad Harry: When you go into Potions class and Snape will not let you in that one room you leave class and go to the next one. After you are done with that go back into the classroom and go in there and nobody will yell at you. You get potions and and other things.
To Make The Blue Eye Dissapear: At the first knight, jump down just so you get on the blue edge. Then walk to your right and jump on the level the knight is on. When he comes alive, count how many steps he takes. When he takes his fourth step, jump to your left so the knight stops. Then walk up the steps and stop right at the step before the top step. Then press up so Harry runs. Then there should be a door next to the bookshelf and run in it. When you find the blue eye, cast a knockback kinx spell at it. Then it will show the blue eye dissapearing.
Plants With Thorns: To beat the plants with thorns after putting Fluffy to sleep, shoot the one lighten up or the greenest. Keep shooting each lighten up one till they all go away. Then shoot a knockback at the one in the middle. Move a little close to it (not too close) and then walk back before it strikes. Shoot another knockback jinx after it strikes. Do this till its health is down then when it has little health you will use the spell where you cast fire. It will be defeated and you can now go to the next room.
Defeating Turtles: If you want to defeat a turtle in the forbidden forest, go really close to the turtle's hole behind it. It will leave out tails of fire. As soon as it leaves out fire, hit a knockback jinx on it. It's shell will turn green. Do the same thing two more times so the shell will turn red and it turns upside down,the tail of fire will make a hole in the tree and you can pass.
Lightning: On the main menu, where the owls are, hit Triangle and lightning will strike
