You can playing slot from Pragmatic Play from any casinos but you should know that if you use the bonus promotions, you must reach the requirement to withdraw your winning and the other things that will be their requirement. Sometimes, the wager is too big and not many of them can reach so they can not withdraw their win money.
This forum have so many reputation casino so that will be your choice to pick one or two or more casinos to find a new experience between each casino. But the requirement will not be the same from one casino to the other casinos so you must think about how much money you will spends to playing slot game.
If you can accept the risk and can fills the requirement from the casino, you are good to go and start playing slot games.
