How to play Great Blue Jackpot mobile slot

The Great Blue Jackpot slot is not a sequel so much as the same Playtech slot you love but with a progressive jackpot that will have you hunting for more than pearls.

Fans of Playtech slots will have heard of, or at least read, the Great Blue slot review. It’s one of the iconic slot games in the Playtech portfolio, and now it has four progressive jackpots.

The Great Blue Jackpot slot gives you 5×3 reels with 25 paylines filled with stacked wild symbols with a 2x multipliers and scatters that trigger up to 33 free spins with 15x multipliers. But now you can also randomly trigger a jackpot game.

The progressive jackpot is local – meaning it will differ from casino to casino as it depends on how popular the game is at the venue you play. The more gamblers play, the higher the build, and the more you can win, much like how the NetEnt Divine Fortune slot jackpot works.

Why play Great Blue Jackpot slot?

If you love the original, play on the original. Jackpot slots have notoriously lower RTPs because part of your real money bet goes towards growing the cash pots.

But, if you love jackpots and you enjoy mobile slot machines with big wins and big mechanics, this Great Blue Jackpot online slot is exactly what you’ve been looking for.

The gameplay isn’t complicated, but that’s the appeal. You have big game mechanics where you focus on just two symbols: the stacked wilds and the free spins.

Great features and great wins

Even without the jackpots, this is a fun high-variance game to play with great features.

The Orca is the wild symbol which comes stacked on all reels. Any wins with a wild give you an instant 2x multiplier, not unlike the original Thunderstruck slot.

Of course, the free spins is where this game shines thanks to the possibility to trigger up to 15x multiplier – which with a 2x multiplier is actually 30x. When you win over 1,000x your bet, you won’t care if you are playing on Great Blue or the Great Blue Jackpot slot.

Both are great machines, but one gives you a chance to win progressive amounts, usually anything between 10,000 to 100,000 in cash. It’s easy to see why you’d pick one over the other.

Bonus Features

Stacked Wilds: The Orca is the wild symbol. The wild comes stacked on all reels and will double any win.

Free Spins: 3 or more pearl scatter symbols will give you automatic entry into the free spin round, with a start of 8 free spins and a 2x multiplier.

However, you then get to pick from a set of 5 pink seashells where you can win anything up to 33 free spins and a 15x multiplier. You can retrigger the free games indefinitely.

The Great Blue Jackpot: This progressive slot jackpot is triggered randomly. Much like the Age of the Gods slots, the jackpot game triggers randomly and can hit on any spin regardless of how much you bet. However, the more you bet per spin, the higher your odds of triggering the jackpot game.

You will then get to pick from a series of coins, pick three identical ones, and you'll win that jackpot.

  • Fish Jackpot: hits under 100 in cash
  • Turtle Jackpot: hits under 10,000 in cash
  • Shark Jackpot: hits around 50,000 in cash
  • Whale Jackpot: hits over 100,000 in cash

This is a local jackpot that grows with the bets from the online casino you play at - so the amounts will be different from casino to casino. The amounts above are general and guidelines only, not definite amounts.


  • 4 Progressive Local Jackpots
  • Free spins with multipliers
  • Stacked Wilds


  • Lower RTP than original due to jackpots
  • Outdated graphics

Great Blue Jackpot Review Conclusion

There's a reason why Playtech studios put jackpots on their best slots; they will be played and enjoyed by millions worldwide who recognise the simple but powerful mechanics.

This might be a little old-fashioned for some, with just 25 paylines and stacked wilds with multipliers, but these kinds of casino games are what made video slots great and adding a huge jackpot only adds to the greatness.

With a decent RTP this is a great find for jackpot hunters, we just wish we could have had a bigger betting range as with the original machine.
