When it's a really good offer it's best not to take the piss as you'll want them to keep sending the offers.
The New WH Casino is something I haven't done before so don't know how it works.
If you currently have £50 in your account that has a 4 x WR attached.
You Deposit £100, WR 4 x on Burning Desire. I lost £40 so I now have £110 in my account, which I withdraw.
The Bonus is then paid in and I have £100 in my account + £110 that I have withdrawn so I have £60 more than I started with. I wait for the next offer so say it's another £100 deposit offer.
Deposit £100 and wager 4x again clearing WR on both the bonus in the account and qualifying for next bonus. I lose £50 on the wagering so now I've got £150, which I withdraw. The bonus gets paid in again and I now have £100 in the account + £150 that I withdrew so I've made £50 this time, and so on. I NEVER clear the bonus wagering unless it's to qualify for the next bonus.
I've done the Texas Hold Em on another account and it's not for the faint hearted. If you have a good hand you'll be wagering a minimum of £5 on it and it's £1 a go just to see your cards. I won big but I'm quite good at hold 'em. Always beat the mates anyway
If you don't know how to play steer clear and wait for the middle of the month which is when Ladbrokes usually release more promo's
