Complete Unwanted Experiment Walkthrough Guide

Unwanted Experiment: Exploring the Basement

Our walkthrough for Unwanted Experiment begins as Erik awakens in the basement of the scientist’s house. The first thing you need to do is explore every room and item inside. Pick up what you can and then start to work out how to solve each puzzle.

Tap on Erik to wake him;

Tap the rope so Erik rubs it on the edge until it frays and breaks;

Try the biometric keypad to discover Erik’s handprint won’t work;

Look closer at the top of the bookshelf;

Open the yellow book and turn the pages to see the picture of a flower;

Check out the box on the lower shelf;

Take the CD from inside;

Tap the arrow on the right to go to the next room;

Take the dart from the dart board;

Pick up the paintbrush from the shelf on the right;

Take note of the red book, the locked box and drawers;

Tap the arrow on the right to go to the next room;

There is nothing in this room to pick up so move to the next room;

In this room there are two tables;

Open the drawer on the right;

Take the flashlight and the transparent sheet;

Look closer at the images on the two notice boards;

Tap the arrow to go back to the first room.

Locked Box Puzzle

Find the red notebook again;

Open it and tap the arrow to turn the page;

Notice how the squares are arranged just like the pictures on the two boards;

Select the transparent sheet in your inventory and choose the ‘grab’ option;

Tap the page to place the sheet;

Take note of the red lines on each page when the translucent sheet is on top:

Right side on top left square – one red line

Right side on top right square – three red lines

Left side on top right square – two red lines

Left side on top left square – four red lines

The number of red lines corresponds with the chronological order of the squares and the symbols on each image;

Go back to the room with the two noticeboards. Look at each of the images in this order:

Right board – top left picture

Left board – top right picture

Right board – top right picture

Left board – top left picture

Each image has a symbol hidden on it, so note them down. These symbols will unlock the locked box in the room with the jail cell:

Go to the room with the jail cell and find the locked box;

Enter the symbols you found to unlock it;

Take the fuse and the yellow key.

Fuse Box Puzzle

Tap on the fuse box and insert the fuse;

Head back to the room with the red notebook for the next clue;

Flip through the pages until you find notes on an experiment to turn a man into a monster;

Tap the image of the man to see the back of the image;

Here you will find the clue to the order in which to press the buttons:

This order may change depending on your version. Just note which position the black buttons are in.

Go back to the room with the fuse box;

Press the buttons in order according to the last clue and take note of how many times each light blinks:

Again this may be different in your version so just note down the blinks for each button pressed. For example: 1st button – 3 blinks, 2nd button – 3 blinks, 3rd button – 4 blinks, 4th button – 5 blinks.

This clue is then used to open the Roman numerals combination lock in the room with the jail cell. So with our example above we would set the combination as follows: III, III, IV, V

Tap to see inside the cell and tap him to speak.

Antidote Puzzle

Now we know the man’s name (Alex) and that his handprint will open the door to the lab. Before he can tell you the password to get the antidote, Alex turns into a creature. Unable to speak, he can only point to symbols:

He will always point to the same four symbols: Serpent, Square, Triangle, Circle. The order may differ in your playthrough.

Use the symbols given to you by Alex to unlock the red box in the previous room;

Take the scissors, bubblegum, and blue key. Now you should have two keys: yellow and blue;

Go back to the room where you were first held. Use the yellow key on the washroom cabinet;

Take the spool of thread and the empty beaker;

Tap on the top shelf of the bookcase and open the yellow book;

Use the scissors to cut the flower from the page;

Go back to the room with the jail cell;

Select the blue key from your inventory and use it to unlock the keyhole to the left of the cell door;

Pull the lever to turn on the light in the cell;

Look inside the cell by tapping the bars;

Now the wall is lit up and you can see four squares to the right:

The arrangement of the squares may be different in your playthrough but the clue is the same. The line drawn on each square represents the order of the squares. The position and order of the squares correspond with which buttons to press to unlock the safe in the room where we started.

Go to the room with the washroom where we first began and tap on the safe. Tap each button as suggested by your own clue. For example, our clue (seen in the image above) shows the buttons should be pressed in this order: Top left, lower center, middle left, top right.

Take the apple, bread, and chemical recipe;

Go to the room with the jail cell;

Tap on the cell door and see there is a bird to the right;

Select the bread from your inventory and feed the bird;

The bird drops a feather but it is too far to reach;

Select the bubblegum in your inventory and choose ‘Chew’;

Select the thread and combine it with the chewed gum;

Use the combo to fish for the feather by selecting the piece of chewed gum on the string and then tapping the feather;

Head back to the room with the red notebook;

Look through the book until you find the recipe and instructions for making the antidote with the apple, feather, and flower;

Go to the laboratory room and tap on the table with the beakers;

Each blender above the beakers is marked with a colored square:

Place each item in each blender according to their color: flower = blue, apple = red, feather – yellow.

Place the empty beaker on the table;

Select the chemical recipe from your inventory. This note shows the order in which to enter each color.

Pour the chemicals in order as shown in the note from the bottom to the top;

Head back to Alex in the jail cell;

Take your dart and combine it with the antidote;

Look inside the jail cell and select your antidote dart;

Throw it at Alex to cure him;

Now we can switch between Alex and Erik via their images in the inventory.

Put the small battery inside;

Open the CD slot at the top and enter the CD from your inventory;

We will come back to this later but for now, move to the next room to the right;

There are tally marks on the wall;

Switch back to Erik and go to the red notebook;

Flip pages until you find images of tally marks and a flashlight;

This shows you will find a clue by turning off the lights and using the flashlight;

Go to the room with the cell again and use the lever again to switch off the lights;

Switch to Alex once more;

Select the flashlight from the inventory and then tap the wall with the tally marks:

You will see a musical note and some tally marks circled in blue. Note down the number of tally marks circled from top to bottom. The answer may differ in your walkthrough but the clue is the same- the tally marks represent track numbers on the CD player.

Switch back to Erik and use the lever to turn the lights on again;

Switch back to Alex and go to the music player;

Tap on the player and listen to the tracks in order according to the tally marks you found. You will hear four different sounds: Laughter, Frog Croak, Bell Ringing, Guitar Sound. These will always be the same but you may find yours are in a different order;

Switch back to Erik and find the red notebook again;

Tap the bottom drawer on the bookshelf to the right;

Tap the drawer to open it and take the paint thinner;

Switch back to Alex;

Good or Bad Ending?

Use the red key to unlock the cell door;

Alex is now free so switch to him to use his hand on the biometric scanner;

You can now escape!

There are now two possible endings: good or bad.

Bad ending – This occurs if you did not pick up the dart earlier, or are not quick enough to react in this moment.

Good ending – This is only possible if you picked up the dart earlier and prepared the antidote-dart combo before escaping. Before you head up the ladder, select the dart you picked up earlier and combine it with the antidote. Use it on the scientist and the game is over!
