One of the most popular aspects of matched betting is taking advantage of offers with big potential.
Taking advantage of risk-free promotions means members can play for bumper prizes with nothing to lose.
There's a lot of luck involved but when it pays off, it can be significant and our members share their success stories in the Big Wins Thread on the Profit Accumulator forum.
Many of the bigger wins come from casino offers.
Some of the casino wins will have wagering requirements but some are cash and can be withdrawn immediately.
Here's a some of this week's big winners (we've left out full names to try to prevent unnecessary gubbings).

Simon said: "Was just doing the low risk Sky Bet Vegas offer. started with £2 spins on rolling stone age, hit a decent win of £32. decided to chance my luck and keep going and got the Dino-mite bonus awarding this "mammoth win" of 284 quid.
"Thats the second time out of two attempts with slot i've won a decent sum doing £2 spins. Definitely seems like the way to go as you get 7 reels and 50 win lines."
