Over the past couple of decades, online casinos have awarded some of the biggest slot jackpot wins of all time. Thanks to networked progressive slots that accumulate massive prize pools across hundreds of online casinos, a single spin can now make a lucky player an instant multimillionaire from the comfort of their home.
While land-based casino wins have produced larger amounts, online slots at Wazamba provide more opportunities for players to hit a life-changing score. Industry experts predict that we’ll continue to see more staggering online casino payouts as technology improves.
Growth of Progressive Jackpots
Progressive jackpot slots are the driving force behind the largest online casino wins. These games connect player deposits across casinos to form combined prize pools that continuously rise until someone hits the jackpot. That creates enormous top prizes that routinely eclipse $1 million.
As more casinos join progressive networks, the jackpots become bigger. The largest online slots can easily accumulate eight-figure prizes before a winner emerges. To put their growth into perspective, here are the average progressive slots jackpots over the past decade:
| Year | Average Jackpot Size |
| 2012 | $1.2 million |
| 2015 | $3.1 million |
| 2018 | $5.9 million |
| 2021 | $9.8 million |
With jackpots doubling nearly every three years, we can expect to see more staggering payouts in the future.
