It would seem as though this summer is a good time to be a fan of casino games – and especially online slots.

Not only is it starting to warm up nicely, but the major software providers don’t appear to have paid out many progressive jackpots recently meaning that the jackpot pools at some of the web’s best casinos like Judi QQ Online have gone through the roof.

So with that in mind, we thought we’d have a look at the amount of money which is currently on offer from three of the web’s main software providers.

Microgaming

Microgaming is widely regarded as the king of Progressive Jackpots, so it’s perhaps not surprising that they’re claiming the top position when it comes to the size of cash which is waiting to be won.

They’re estimating that their current prize pool is worth around $5m with the slot games Major Millions and Megah Moolah making up the lions share of this amount contributing $1m and $3m respectively.

In fact, this is the first time in more than two years that the progressive jackpot on Major Millions has crossed the $1m mark.

Traditionally speaking, the game usually pays out slightly smaller amounts more regularly, but with no winner triggering a big payout recently, the size of the jackpot has increased substantially.

To be in with a shot of triggering any of these jackpots, we’d suggest that you head over to JackpotCity Casino, which is one of the largest and most trusted Microgaming casinos around.

Unfortunately, US players are not accepted by Microgaming at this time.

Playtech

Only just missing out on top spot is Playtech who are estimating that their current jackpots are worth $4.8m.

With a slightly different structure to Microgaming, the Playtech jackpots draw their strength from a larger number of games, each offering a slightly smaller cash prize.

That doesn’t mean that there aren’t life-changing amounts of cash on offer though.

For example, Beach Life has always been Playtech’s flagship slot and it’s easy to see why when you consider that its jackpot has been growing by around $20,000 per day recently so that it now stands at a huge $1.8m.

This makes it the fastest-growing jackpot on the internet as it was only three months ago that the jackpot was last won reset to just $50,000.

Aside from Beach Life, Playtech also has the hugely popular Marvel slots – all of which contribute to the Marvel Ultimate Power jackpot which, at the time of writing, is worth $800,000.

Those of you wanting to try your luck on these jackpots should head over to www.omnicasino.com.

Omni Casino has long been our Playtech casino of choice thanks to its excellent customer service and long-standing history of excellence in the industry.

What’s more, as a BestCasinoOnline.com reader, you’ll also be eligible for an improved 150% welcome bonus when you make your first deposit.

Unfortunately, our US readers will not be accepted at any Playtech casino at this current time.

Real-Time Gaming

If you’re based in the US, you may be getting a little concerned that you’re being frozen out of the big money games which are currently available with Playtech and Microgaming.

Well, never fear because Real Time Gaming accepts players from all over the world and they have got some pretty big jackpots to shout about as well.

In fact, RTG has just announced that their Progressive Jackpot levels are pretty much on a par with Playtech. They estimate that they currently have about $4.7m which they’re waiting to payout.

The size of this jackpot predominately comes from four main online slot games – none of which have been hit for the last couple of years, and as a result, now stand at over $1m each.

The largest of these games is Jackpot Pinatas which currently has a very attractive progressive jackpot of $1.7m. This is closely followed by Aztec’s Millions ($1.3m) while Mid Life Crisis and Shopping Spree both have jackpots worth over $1m.

If you’re looking to grab your share of these prizes, then the best RTG casino out there at the moment is Judi QQ Online.

Not only can new players get their hands on a mouth-watering $7,777 welcome bonus, but they can also benefit from some of the best customer services around.

And if that wasn’t enough, the whole place is themed on the swinging 1920′s and is arguably the best looking online casino around at the moment.
