There are five requirements in total.
1) Get rid of the drilling noise outside.
2) Make sure there are no distractions.
3) Do something to block out the bright lights.
4) Find a nice cosy spot to take your nap.
5) Make sure the boss can't catch you napping on the job.
How do I stop the drilling noise?Spoiler
This is the easiest 'puzzle' in the whole game. Simply close the window by clicking on it once.
How do I make sure there are no distractions?Spoiler
Perhaps there is a way to stop the phone from ringing.
Spoiler
Try unplugging the phone.
How do I block out the lights?Spoiler
If the boss sees that your light is off, or that your blind is closed, it may arouse suspicion. Maybe there is some other way to stop light from reaching your eyes.
Spoiler
Maybe you could use a blindfold.
Spoiler
Try fashioning one yourself from the items you are carrying.
Spoiler
Are you carrying the elastic band? (If not, click on the desk.)
Spoiler
Are you carrying the two leaves? (If not, click on the plant on the shelf)
Spoiler
Combine the leaves and the rubber band to make a rudimentary blindfold.
(You don't have to do anything with the blindfold. Simply having it means you have solved this puzzle.)
How do I find a nice cosy space?Spoiler
You can't sleep at your desk. The boss could see you through the window.
Spoiler
How about that big open space on the floor beneath the notice board? Try clicking on the space. Oh. It says you need some sort of pillow.
How do I make a pillow/cushion?Spoiler
Well what is a cushion? It's a piece of fabric with some kind of stuffing.
How do I make stuffing?Spoiler
Maybe you can use the shredder for this?
What do I shred?Spoiler
Try clicking on the small note of the noticeboard for a clue.
Spoiler
The note says the newspapers will be ready soon. Try calling reception again. This time you can request a newspaper.
What can I stuff?Spoiler
How about some item of clothing?
Okay, but the cushion is falling apart. How can I keep it together?Spoiler
There must be some generic piece of office equipment designed for just this kind of problem.
Spoiler
Use the stuffed jumper on the stapler. Now you have a cushion.
What do I do once I have a cushion.Spoiler
Use it on the space beneath the notice board. Now you have a cosy place for your nap.
How do I make sure the boss can't catch me.Spoiler
You have to make it look as though you are still sitting awake at your desk.
How do I do that?Spoiler
Perhaps if you had a picture of yourself.
Spoiler
You can photocopy your own face.
But the photocopier won't work.Spoiler
It needs more paper. There is some on the shelf.
Thanks. So what now?Spoiler
Well, presuming you have sellotape and ruler, you can just stick the photocopy to the ruler.
What sellotape? What ruler?Spoiler
Did you even try searching the desk?
Spoiler
Oh. Whoops.Spoiler
Whoops, indeed.
Okay. So I think I've done the five tasks. What next?Spoiler
Well now you can take a nap. So what better time is there to press the 'Take a nap' button. If you are still yet to fulfil the requirements, the game will let you know.
