hellooooo! anyone here?

ello, cool a new one :)

eeewwwww! gross! frog experimentation!

hi! have three marbles, now stuck with only a microscope

opened box under blackboard

Have 4 balls now....for the 3 digit code look out of the window and then the chemical poster

For the squares code look at the books.

how do you get the 4-digit code?

@LS for 4 digit code for box under blackboard, look at the diagram written on the blackboard and written words underneath

anyone help me with the clue for the dials in the cupboard?

POP! Don't worry!

thx dideedi, i was always trying to match the OHNO with the chemistry code below the table...
the code for the dials is behind one of the notes...

I have to go, GL all !!!!!!

out !!!

yay! we have screwdriver!

out too. love these grayscale games!

thx dideedi, but now stuck with four marbles...

... and a microscope... Why is it still there?

@ls: how did you do that?

@escapism, have you got the marble from the stool? that was my last one

Ahhh, out too. Haven't found the marble in the chair earlier. Out too!

Thanx a lot LS!! POP helped me!

Did we use the closed drawer? I don't think so. Weird...

wasn't the microscope there? or do you mean the "empty drawer"

i see the bugs but the shapes escape me plus diff # of legs??

Ah, ok, I replayed it, the closed drawer was opened with the white key and didn't open again later... strange

Can´t figure out the 4-digit code. I have read the comment but I don´t understand.

@threefiftyone...: yes, the number of legs is important...

@madde: didn't get that too in the first place. It took me a while to get it.


Count the number of O's, H's and N's in the diagram on the black board..

count O's H's and N's Madde

@ls: the matches have been there...

@351C1971: If you still need the shapes, I wrote it down, so here they are:


i had that order but it was saying i needed to see clue so i thought the odd shaped circles might be something else. thx again now out

Where is the hint for the shapes code (square, circle, etc) ? And what about the 4 digits code ? I thought that we had to use the table for OH NO (7417), but that's wrong.

Stuck: only microscope in inventory, test tube is gone (don't know where), all boxes opened, need one more marble, fire started, can't do nothing with the metal block... so very stuck!

Adryanna, if you lost the test tube and still have the metal block you probably have to start over. I did not get the HNOO clue as well.

don't have metal block, can't take it out of the box. maybe a bug?

No, you change the metal bloc into something else with the heated chemical in the test tube.

oh, well. then, I'll have to restart. thank you for helping me.

You are welcome. What about the clue at the blackboard?

Is anybody still there to helpme with the HNOO clue?

Hey friwi. You have to count the O, H and N in the
shape at blackboard and then use them in order of OHNO. I hang on and see if you get it...

Stuck with what to do with the test tube..have flame but it wont heat?

Friwi...count the # of each letter on the board.

Thank you Madde, I did count them, but see only one H with phantasy one N and no O altogether. Derek, did you fill the chemical into the test tube first?

friwi you have to raise the blackboard again so you can the complete picture.

Oh, how? I feel pretty dumb!

@friwi: look at the drawing in the upper left corner, not the one in the middle/rightcorner...

cant find 5th marble. got one from chair,one from box one from metal sheet can't remember other one. anyone help??

Chemical? Hmm no. Guess that would help lol
Opened all boxes and drawers. Cant imagine where it would be?

I'm totally stuck with only 3 marbles, a testtube and a microscope. Thanks to Madde's message, I could open the 4 digits codebox, but I don't know how to use the hint given by the bugs. Which one is the first shape ? From the top, it seems to be : circle circle triangle triangle square, but that's not the answer.

NVM got it and out!

Do I have to start over? I already found the button that made the blackboard fall and don't have the clue ...

@pascale: look at my postings from 5:27, it is


Count the legs. I think it starts with 4 legs, then 5, then 6...

@nokra: no, just push the button again...

OMG! I just don't get it!!! I opened the box with Madde's numbers, but don't see any drawing in the upper left corner of the blackboard. Tried to give in cheated shapes, but it tells me, I have to see the clue first.

... For the order of the shapes, count the numbers of paws of each bug.

Where is the chemical for the test tube ?!

Well, finally got it. WIth the button right of books you raise the blackboard. And you can give in the shapes after you clicked on the bugs under microscope!

Thanks! Saw your clue, @maddie....this is a very well made game....things work in reverse and stuff is easy to see and understand...love it!

Pascale, you will find the chemical, when you lower the black board.

Thank you Friwi!!! Totally missed the button next to the books. I could see the clue and the safe where you place the balls with the board down so had no idea you needed to raise it.
Finally out.

Thank you, Friwi, how do you lower the blackboard, please ?

TY , also, @escapism...I was too busy playing to refresh...LOL Thanks to all the great clues...I am out!

@pascale....move the books to right of it to find a button...It lowers ...and goes back up...LOL

second one today without help. The happy coin is still working!

Thanks a lot, Nokra ! Now I'm out !

Oh I lost test tube as well.. I wonder where. I thought i tried it on the metal, but nothing happened - maybe I forgot to heat it up. i had the chemical in it. Back to the beginning for me!

Hi all. Is there a hint for the 3-digit code somewhere? I'm stuck there...

3-digit code:

Square code:
2 clicks, 0, 1, 3, 0, 2

4-digit code:

Shape code (click on the bugs before entering it)
triangle square circle triangle circle

Last marble:
Right chair

hint: do not put knife or chemical on microscope it will disappear and you have to restart :P

Well still no NEW games, so replaying...

how the heck do you get the microscope out of the closet?

you need the black key from lockers:
adjust every switch in each locker (except first from left, where you get key) according hint on pin board.

You have to click on the bugs before you can open the shape box or else it just keeps saying guessing wont help, you must find a clue!

Bug? I drag objects into microscope view and they disappear.
