Cheers for the screenshot @ezkilzon and sorry for the slight delay in service. What happens whe you click on the lock and select "Allow"?
Please note that the result might differ if you choose "Allow (default)" ant the slot won't launch.
Some slots are Flash based like this one and others run on HTML5, so indeed there is a chance that some of them launch and others don't.
Notice that it appears like flash is not allowed, but only in "real money"-mode. That is the strange thing about it. In "fake money"-mode it works fine. I wrote this a couple of times now. I have cleaned cookies and so on, Notice that it appears exactly the same when I use Microsoft Edge instead of Chrome. It`s frustrating cause I only use Unibet för this game.
