Please Help Me understand How Wager Requirements Work

Excuse the question but I am new at this and I have been studying pretty hard  but I can't seem to grasp how the wage requirement works.
First question:
Ok so for example, I deposit $100 into a casino that offers $200 bonus so that makes for $300 that I have to play with. So their wage requirements 20 X B (20X 200 = 4000) or is it ( 20X300 = 6000)?

Second:
Assuming the wage requirement is 4000, what does that mean exactly. Also assume that I am betting $1 per turn/round/spin, Does it mean I have to play 4000 times, does it mean I have to earn $4000, does it mean I have to wage(bet) $4000  but I only have $300 to start with? I just don't know at this point what I am suppose to do and how I am suppose to do it to meet the wager requirements.

Thx for the help

Yes - that is exactly right.  Assuming the assumptions i.e. $300 x 20 WR you have to spend $6000 in any way to meet the wagering requirements.  Once you have physically spent $6000, then you can cash out but watch out for the max withdrawals etc.

Best of luck.

But if you don´t use a bonus, is it common that you have to wager the deposit anyway?
I read this in Gold Rock casino´s T&C: Deposit made without any addittional bonus must be wagered ten times (10x) its sum in order to qualify for withrawal.

I thought I could just deposit, win money and get out whenever I wanted if I didn´t use a bonuspromotion, or did I understand it all wrong?

It seemed really strange to me, but I asked livechatt just now and it was to prevent laundring she said. They have never denied anyone to cash out if they wanted earlier and I do believe her. She was very friendly and gave me $10 for free when I asked if they use to give free money to depositers
