Progressive slots can have huge jackpots because they’re often linked across multiple slots. For example, the same jackpot might be offered at Slot A, Slot B, and Slot C. Whenever anyone
plays one of these three slots, the jackpot increases, and anyone playing any of the three slots can also win the prize.
What’s more, jackpots are often shared across multiple online casinos. For example, the Mega Moolah slot – perhaps the most famous online progressive slot in the world – can be played at most online casinos using Microgaming software, which means it can be played across hundreds of sites.
So, this means that many people can be playing many slots at the same time, all at different casinos. And this means the jackpot goes up very quickly. The more popular the slot, the faster the jackpot rises.
