In honour of Halloween, Grande Vegas Casino has launched a ghoulish week-long freeroll slot tournament that is promising to hand out $3,100 in total prizes.Beginning today using the new five-reel Count Spectacular slot from developer RealTime Gaming, the competition is challenging players to rack up the highest score before midnight on Sunday.“I think the reason tournaments are so popular with slot players is that you can win nice price money without spending a lot,” said Robert Miller from Grande Vegas casino.“And when it’s a freeroll, of course, it costs nothing. I think players like the idea of competing against other players, too, rather than just playing against the machine.”
