No Internet = No Life? No Internet (2 days) = $1000 free money

FA few years ago, I heard a similar story.

A company offered a small amount of money if the staff don’idn't use mobile phones at work.

An other suggestion would be:
I was about a company offering a small amount of money if the staff didn't use mobile phones at work.

We never refer to phones as mobiles. They can be referred to as phones, smartphones, cell-phones, or mobile phones. At least where I am, the term mobile phone sounds a bit more dated than the others.

Camping 2 days with no internet.

I would suggest as well:

Camping 2 days without internet.

What you have works though!

99% of my friends said it is too easy!

Maybe it is a charitably campaign.

(not camping…Www)

This doesn't make sense to me.

The w's don't mean anything to me either.

If I amwas the organizer or I canould make a suggestion.

Let’sI would change the rule to “the more days nowithout internet life,, the more money one gets”.

Now, the economicy is bad, the big companyies should use thisese kinds of games to help the poor.

economic is an adjective

You could also say:

Now, the economy is bad, the big companies should use this kind of game to help the poor.

Note how the plurality between this/these and game/games agree
