A progressive pokie is exactly the same as a normal pokie, with the exception that it does not have a fixed jackpot. Every player that plays will have a small portion of their bet transferred into a pot, which grows as more players enjoy the game. When a player wins the jackpot, they will claim the entire pot, which could be worth millions of dollars. Some progressive pokies are also linked across hundreds of online casinos all over the world, so their jackpots grow to huge amounts very quickly.
