Last update: 29 December 2020

Hogwarts

You will begin in the Gryffindor Common Room (M2.15). Go outside and follow the ghost to Hagrid's Hut (M3.24) - you will come across another student on your way. Head towards the Bathroom Hallway (M1.4), head onto the upper floor and destroy the blockade with (RD) #1. At the end you will find Moaning Myrtle - follow her into the bathroom #2.

Secret of the Egg

You have to collect four green shells and place them on the wall. The first is right next to you #1. Head left - there are three leaking sinks there. Use magic on them #2 and eventually the shell in will fall out of the container beside.

Approach the wizard painting - in one of the cabinets on the right you will find a couple bricks - assemble (WL) an umbrella from them #1. Hand it over to the Wizard - he will clog the hole and give you a shell. In the barrel, right next to the chest with a Boggart, you will find a couple bricks (WL) #2. Assemble a toilet seat (WL) from them.

Use (WL) on one of the planks #1 - the ghost will do the same with the other one. You will receive a shell; go down the stairs #2.

There's a broom by the pool - clean (WL) the stained-glass window using it #1. The siren will throw out a box with crabs - destroy them all and make a small railway from the bricks (WL) #2.

Use the cloud (WL) by the column on the siren to fill the stained-glass windows with water #1. In return you will receive a valve - place it on the right side and turn (WL) #2.

Hogwarts

You begin in the Main Hall (M1.1). Follow Nearly Headless Nick to the Black Lake (M3.27). Destroy the entrance gate with (RD) #1. Go down the stairs and towards the gate behind one of the professors #2.

The Black Lake

NOTICE: The construction of this level is somewhat different from the other ones.

Swim to the right and you will reach a pipe #1, thanks to which you will get closer to the screen. Keep swimming right. The next pipe will be blocked - use magic on the rocks #2.

You can either swim to the other side or to the right. Whichever option you choose, you will reach an octopus #1. Unfasten a tentacle with (WL) - the second character will do the same with the other one. Continue swimming right. You will eventually reach a blocked passage - on two rock ledges you will find two big bricks - attach them (WL) to the middle one #2. You will create a fish which will make the big boulder fall.

Just like before, swim right in the next location. One character will take the lower route and the other one the upper. Switch to the lower character, lift (WL) the door blockade and swim below it #1. Place the giant crab (WL) on the purple bricks on the left #2.

Switch to the upper character and use magic on the octopus' eye #1. Get rid of the Devil's Snare (LS) blocking your way #2.

Up you will find a red bush - after using magic on it, a pearl will fall out #1. Place it by the shellfish blocking the passage below #2.

In the last part you will come across sirens - look out for them. Destroy the rocks surrounding the pipe entrance #1. Before you swim through, there's an anchor on the right and left - use (WL) on them. Additionally you need to chase away the Devil's Snare on the left with (LS) #2. Swim through the pipe.

Place the violet pearl on the scale #1. Afterwards use (WL) on the anchor. Once you have a blockade by every chain, use magic on them and they will break #2.

Hogwarts

You begin at the Grand Staircase (M2.8). Wave to the wizard on the picture #1 and he will move the stairs. Go up and wait a bit for the further stairs to appear. Destroy the chest and throw the wheel (WL) #2 to the wizard in the picture. Afterwards use magic on him and to switch the stairs.

Wait a bit again. Eliminate two pixies (IM) holding the painting #1 and place it on the wall (WL). Use magic on it and the wizard will switch the stairs. Enter the Dumbledore's Office (M2.10) #2.

The Dark Lord Returns

Use magic on the four bushes round the base of the statue and then assemble (WL) the gold armour #1. Use magic on it and keep a track of its sword movements #2. The order of passages you have to take is being shown. The statue keeps on moving all the time - you have a limited amount of time to get out of this part of the labyrinth.

Exit route: right, left.

In the further part, eliminate the pixies holding a part of the armour with (IM) #1. Assemble the armour (WL), use magic on it again and it will show you the proper way.

Exit route: left, right, down.

In the third part, chase away the Devil's Snare (LS) and put together (WL) the armour #2.

Exit route: right, left, down, up.

You will find yourself in a labyrinth. Go forward - you will come across moving walls #1. Wait for the passage to be clean, head forward and try not to be pushed. This situation will repeat three more times #2.

You will eventually reach a spot with a pixie holding an arrow on the right #1. Eliminate him (IM), place the arrow on the pole and use (WL) to turn it #2.

By doing this, you will move the wall on the left - move on. You will reach a sphinx #1 - head left and use (WL) on the big, green book #2. Bricks will fall out of it and an image of a sphinx running away from a spider will appear.

Assemble the bricks (WL) into a trampoline and jump behind the fence. Chase away the Devil's Snare (LS) and place the fly (WL) on the spider-web #1. A spider will show up and destroy the fence. Assemble the fly (WL) and place it onto the sphinx #2.

You will have to fight Lord Voldemort. Keep eliminating the Death Eaters as they appear #1. Once you face Voldemort himself #2 keep on pressing [H] to cast a stronger spell. Repeat it three times.
