Boredom at work - What do I do about it?

I have my last week of work with my current employer this week.

Since I have already handed over most of my tasks and anyway in the summer hole is nothing to do, I'm now looking for a job on the PC to pass the time. I can also use my notebook without restriction in private - but it is not suitable for playing real games.

Someone like an idea how I got through the last two days without dying of boredom?

I do that all week.

Answering questions is always an option!
Alternatively, of course, goes the following:

Online Games:

Surviv.io
Agar.io
Slither.io

Good entertainment:

9gag.com
reddit.com

Videos on Youtube:

Near Death Compilations
Car crash compilations
Primitive Survival
Other videos without sound

The .io Games I have already over and YT I've already felt through completely. Can also watch with sound.

Learning a new language.

Did I actually start with → Dutch. However, I could not find a suitable platform for it on the internet. Do you have a tip?

Langues is pretty good.
