I've been getting destroyed lately and am very low on cash.
I got a 50% cash offer from Sportbet and 100% free play offer from a book that I keep losing at.
I've done the math and they're both about the same.
I'd really like 100% cash but I've exhausted those promos - unless I have missed some of the books. I have played at Jamaica, can't get it at Looselines.
Many factors. Without getting into a comparison of the actual safety of the books, I'll say this:
100% freeplay should be worth a lot more than 50% cash.
If it is just an open freeplay, I could turn it into at least 75% cash with minimal effort.
But some books have rules that limit what freeplays can be used on and that also limits the return. Even at a book like Bookmaker with pretty restrictive rules, I would turn a 100% freeplay into more than 50% cash though.
There are freeplay maximization techniques that involve playing both sides of a bet at different books. I don't know if you understand the techniques or have multiple books. If not, I'd probably just grab the 50% cash.
