What's video poker without gambling feature? Sounds pretty stupid to me, to be honest. I do agree that gambling on video slots
is rather boring since it's just boring gamble there. But for video pokers I do like to have the gambling feature enabled.
And you clearly haven't searched well around, but there are casinos that allows both no double feature and even half-double. And on some casinos you CAN turn the double feature OFF in the settings, but unfortunately, I don't remember which casino that was.
I do understand that there are users who are strictly against doubling their winnings, but it's rather easy for them to just continue their play by just hitting the "deal"-button again. Because if you really wish to double, you have start hitting another button instead, so yeah.. it's fairly easy to avoid or even ignore it, girl. Hehe.
I have a very easy rule, which seems to be working really well MOST of the times; If I get the lowest wins valued at 5, I double them to either 10 or 20. SOMETIMES if I've got a nice balance, I even go to 40. If I get a win with value of 10, I double it to 20, so only once. Fair and easy. The rest I just cash in.
