The best way to practice for the Slot tournaments is just to play regular Slot games online. Of course you don't want to be losing too much money in the meantime - always only play with what you can afford to lose - this means you'll always enjoy your gaming. Another way would be to play at a site like FREESLOTS where -as the name suggests - you can play Slots for free - this way you get to practice for the real competition without dropping any money.
