Certainly one of the most exciting online slot machine games from developer GameSYS, you’ll be able to get hours and hours of enjoyment out of Double Bubble.


A full-blown retro style slot machine re-created perfectly on the computer or your mobile device, you’re going to find the Double Bubble slot machine to give you that throwback kind of “Old Vegas” play style so many people are after these days.

All of your favorite and traditional slot machine symbols are here (complete with the Super 7 and the BAR symbol), and the overall look and feel of this mobile/computer slot machine is about as vintage as it gets.

You’ll have the opportunity to start your bets off that just one penny and have the chance to win a jackpot of $20,000 – but when you combine the double rewards (the reason behind the Double Bubble name) you’ll have the chance to win even more!

Gameplay is super simple and straightforward, with you having the opportunity to play between one and three different reels. Depending upon your bet you’ll have the chance to hit the Double Bubble bonus (there are two of them) and if you land on that spot you’re going to be able to multiply your winnings dramatically.

A winning pull is going to be represented by old-school “melons”, but if you hit a bunch of grapes are bunch of cherries in a row you’re going to go right over the top as well. Be on the lookout for Super 7s or a “full boat” of BARs, as that’s going to be a big-time payout as well!


As we highlighted above, the graphics behind this slot machine are as vintage and retro as they get but that’s a big part of the field were behind Double Bubble.

You’ll feel like you are playing a slot machine in the heyday of Las Vegas when it was first getting started, and it’s definitely something different from the glitz and glam you’re probably used to from most modern online slot machines.

Special Feature

Double Bubbles are the special feature that you’ll want to be on the lookout for here. If you hit any of these bonuses your winnings are going to shoot right through the roof, and you’ll know it immediately since the “JACKPOT” will be triggered!
