you wouldn't leave your machine logged in and spinning in a real casino while you got a bite or had a pee break, would you? that's what i thought, abuse i say!
They added in the autoplay so that people would do just that (nobody will steal your machine at home).
There's only one reason they added it - autoplay = faster play = more profit for the casino.
In this case though because of the bonus it means the player can 'beat' the bonus that much quicker. It's sharp practice to ban it though, without a BIG warning to the player, because it's an essential feature of the casino software.
This is not the act of a casino concerned about treating its fair play.
See for instance Captain Cooks Casino.
Visit the site,
"We will give you 1 hour and $500 to make as much money as you can".
Hmm, ok, click on the link.
Then "Want to know more, click here"
Cool, that goes here:
No mention of anything about autoplay at all....
So you play, and win, and then after playing for a while you're bored and use the autoplay feature.
Cash out.
"Sorry sir, we are going to steal your winnings."
Why?
It's not mentioned on that page, nor linked from there at all, but if you go back to
then click on
"Terms and Conditions"
Then read "Bonus Account Terms and Conditions" (there are a total of EIGHT pages linked from there to read), it's hidden away there...
This just isn't a fair way to run a casino.
