I forgot to "Opt In" to the welcome bonus when I signed up back in 2014 or perhaps didn't even realize I needed to do so in order to receive the bonus. I needn't have worried though as it took just a couple of minutes to contact support, request the bonus be added and have it in my account ready to start to play.
There are two time limits attached to the bonus, firstly you must make your deposit within 60 days of signing up at the casino to be eligible and secondly you have 14 days to complete the wagering requirement from the time the bonus is granted. Although neither of these time limits should cause problems for the majority of players I have missed out on the occasional welcome bonus in the past when I have signed up at a casino to get a no deposit bonus and then forgot to go back for some time - it just seems a little tight to me, but the 14 day wagering limit shouldn't cause a problem even for those who take the maximum £200 bonus unless you REALLY like to take your time!
Deposit plus bonus wagering is getting more and more common even at the good casinos and I was pretty gutted to see Mr Smith's wagering listed a 25x(D+B) on this page - upon checking with the casino it seems this is a mistake and it remains at 35x the bonus amount only just as it was when I signed up. That's not quite the lowest but definitely amongst the best you will find in 2016.
All games are permitted and there are no restrictions on NetEnt's Dead or Alive, which I always make a point of checking for before I take a bonus now! Another NetEnt game, "Blood Suckers" does have a reduced contribution percentage of just 5%, the same as Blackjack and Video Poker. This is because it has one of the highest returns of all on-line slots and is frequently used by advantage players so I think the casinos can be forgiven for restricting it in some way.
