How progressive jackpot slots work is fairly straightforward in that the cash prize is paid out when a player wins. However, wide-area games boast the largest jackpots – up to millions – but the chance of hitting this jackpot with progressive slot machines is. Standalone progressives have a smaller jackpot but the chance of hitting it is much higher, while local progressives have a medium jackpot which is less likely to hit than standalone. The best progressive jackpot slots depend on what features you find most enjoyable and how much you’re willing to stake. What are the best progressive jackpot slots?
