I only joined for the lotto - having recently decided to no longer use the National Lottery due to their imminent 50% price increase for tickets, and looking for an alternative.
I deposited £10 and received £25 in credit on top of this - resulting in £35 in total. So far so good, although I'm not into bingo or any of the other games as all I want is to buy/place my lotto tickets.
Anyhow, I then saw that they give you an additional £20 credit for every friend that you recommend to the site, so I also did this. My friend also joined and deposited some money of her own, but my account wasn't credited. So I spoke to the online help, and they informed me that the 'friends' in question have to spend £40 or more before I get the £20 credit, which wasn't actually explained in the pop ups asking people to recommend friends (surprise surprise), but is explained should you be bothered to click the appropriate links and peruse all of the fine print.
I then received an email informing me that I'd won £20 on the lottery, but then when I logged in and attempted to transfer the money back into my bank account I was informed that I can't actually do this for another two weeks or until all of the credit has been depleted/spent.
In other words, this site are not interested in paying out, they're only interested in getting people to become addicted to their games and keep depositing money to do so, and they have lots of intricate ploys in place to 'hook people in' in the interests of doing so.
So...as the title of this review suggests, my advice would be to read the small print before you deposit money, although if you can just avoid them all together and find another alternative.
Personally I'm joining the Health Lottery, and that's what I'm sticking with from now on.
