The Quidditch World Cup

You have to save five friends from the hooded wizard. George is on the right side of the camping site. Destroy the rockets flying round him #1. The other Weasley brother is lying under the table - attack the wizard twice #2 and pick up the table with (WL).

Head to the right side of the field and you will find Mr Weasley next to the cauldron. Use the large frying Mr. (WL) to hit the wizard #1. It's time to create the Invisibility Potion. You can find one of the ingredients on the grill #2 - use magic and you will light a fire.

On the right you will find a spider-web - use magic on it and a spider will fall down #1. In order to get the third ingredient, switch to Hermione and use Crookshanks to dig the bush #2 which will give you a cherry.

Drink the Invisibility Potion, approach the red book #1 and jump onto it. Push (WL) the car to unlock the passage. Use (WL) again on the tent to save Fred #2.

You need to get to Harry. Destroy the white banner and construct (WL) a trampoline from the bricks, thanks to which you will be able to jump over the flames #1. Destroy the chest blocking the water barrel #2 so that it can put out the fire.

Approach the chest and use (WL) on it - the second character will get a water barrel out of it #1. Use it (WL) to extinguish the fire by the tent. Switch to Hermione and use Crookshanks to dig up a wheel. Install it to the car #2 and push it lightly with (WL).

Go right - turn round the knocked over cauldron #1 with (WL). In the orange chest you can find an axe - use it (WL) to chop off the brick blocking the passage. Destroy the chest and the barrel - a skeleton will appear #2 and after a while you will receive a potion ingredient.

Eliminate the pixie with (IM) - pick up the tap and place it into the barrel, which will fill up the bucket with water. Extinguish (WL) the flames #1. You will find another ingredient in the hole. A bit further there are planks and boxes lying on the ground - destroy them and pick up the potion ingredient #2.

Drink the Strengthening Potion and pull the chain by the gate #1. You will have to face the hooded wizards. The task is easy - you have to fight off three waves of enemies. Eliminate the targets with a plain spell #2. If you get caught by a snake, switch to the other character and kill the reptile. First wave: six hooded wizards. Second wave: eight hooded wizards and three snakes. Third wave: six hooded wizards and five snakes.

Hogwarts

You begin in the Entrance Hall (M1.2). Follow Nearly Headless Nick to the Potions Classroom (M4.42). Inside you will learn how to create the Aging Potion which will allow you to cross magical barriers. Use (WL) on the books by the pipe entrance - you will create a passage between the tables. Switch to Hermione or Ron and use Crookshanks / Scabbers to get inside the pipe #1. At its end you will activate a mechanism which will lower the cage. Once the bird flies down, use magic on it - you will create two pieces of meat. Place them on the aquarium (WL) #2 and the fish will eventually jump out for it. Take (WL) the potion ingredients and throw them into the cauldron.

On the left you will find a head - use (WL) on the horns and once the wall opens, use Hermione to read the signs on the shelf #1. Place the bricks (WL) on the empty table. Open the book - it contains three differently coloured beakers. On the table, apart from an empty vessel, you will also find beakers filled with three fluids - red, yellow and blue #2.

To create specific colours, you have to mix:

Red + Yellow = Orange

Red + Blue = Green

Yellow + Blue = Green

You will receive another potion ingredient.

On the right side of the room you will find a locked chest - use magic on it and then place the brick in the empty spot by the two water containers #1. Jump on one of the platforms - the second character will jump onto the other one. Wait a bit for the water to be pumped through and you will get the next ingredient. Drink the Aging potion and go through the barrier #2. Head back to the Great Hall (M1.3) and then to Hagrid's Hut (M3.24).

Dragons

Go right - a red dragon is blocking your way. In the bowl by the cage you will find a purple egg - move it up (WL) #1. Afterwards destroy the padlock and go inside. Steer the egg (WL) so that is gets to the dragon cage #2. Eventually a small dragon will hatch and the path will be unlocked.

Eliminate (IM) the three pixies holding the parts of the chain #1. Afterwards put it back together (WL) and pull with Hagrid - you will open the bridge. While crossing it, look out for the flames coming out of the wall on the right #2.

Use (LS) to chase away the Devil's Snare and use magic of the leaves - assemble a mushroom (WL) #1. Jump up, make a chain from the bricks (WL) and pull it with Hagrid to lower the bridge. You will end up by a green dragon. Unroll (WL) the xylophone on the left #2. Colourful notes will start appearing from the dragon's mouth - hit the proper keys with the mallet (WL).

1. Red, yellow.

2. Green, yellow, blue.

3. Red, yellow, blue, green.

The dragon will fall asleep - you can move on. Jump between the flames #1. On your way you will come across four groups of flames. Use the bowl (WL) on the aquarium to gather some water and then pour it onto the flame #2. Make a staircase from the planks (WL).

You will come across a blue dragon. Grab the purple ring (WL) and direct is so that the dragon starts breathing fire at the attachments. With the first and last one, set the ring so that the attachment is in the centre. As for the middle one, place the ring between the first and second attachment #1. After unlocking the path, move on - you have to create a bridge from the bricks (WL) #2.

In the next location, use (WL) on one of the chains #1. Hagrid and the dragon handler will take care of the other ones. At the next location, use Fang to dig up a hole in the ground #2.

Go down with Hagrid and pull the chain - you will unlock the upper passage. With Harry upstairs, put on the Invisibility Cloak and go past the dragon #1. Remove the vines from the road (LS) and use magic on the plant - you will unlock a passage below #2.

Pick up large brick pile (WL) so that Hagrid can move on #1. Once by the tree, pick up the pile again (WL) - Hagrid will use the mushroom and this way you will be able to go through the tree, so move on right. Dig up the chain with Fang, pull it out using Hagrid (WL) and eventually destroy the lock with Harry #2.

Hogwarts

You begin in the Gryffindor Dormitory (M2.16). Follow the ghost to the 2nd Defense Against the Dark Arts Classroom (M4.46). You will learn the Reducto spell (RD). Your task is to save five students crushed by silver items #1 using the (RD) spell. You shouldn't have problems with locating all five in this small room. Lower the cage and head towards Hagrid's Hut (M3.24) where you will find a tent and professor Dumbledore beside it #2.

The first task

Run right and look out for the dragon. Once you get to the blockade, destroy a few brown stones lying on the ground and create a (WL) dog #1. At the very end on the right you will find a purple platform - place it in the caving between the bricks #2. A few black ones will fall out - create a cauldron from them (WL).

Assemble the skeleton (WL) #1a and you will get an ingredient. The second one is right beside, covered with vines - use (LS) #2.

The third one can be gained from the snake body on the left side #1 - use magic on it. Drink the Strengthening Potion, jump onto the platform and pull the chain #2.

Jump up and place the platform (WL) in the middle of the pit #1. You need to pass through the next couple rock platforms quickly, as the dragon breaths fire onto them #2.

Once you're on the last one, use the water barrel (WL) to extinguish the flames #1. Switch to Hermione and use Crookshanks to dig out the blue brick #2.

The red one is being held by a pixie - eliminate it with (IM), while the green one is on the right side - destroy the construction using magic. Set the bricks on the right spots (WL), the bricks colour has to match up with the skeleton helmets #1. Jump up to get the egg. The nest phase is running away. Jump run straight (in the direction of the screen), while avoiding the obstacles and jumping over the holes in the floor #2.
