Jokers are an inseparable part of the best online slots. Often used as Wilds or Special Symbols that trigger exciting features, when you see a joker in a slot, you know it’s a thrilling trip ahead. That’s the case with Betsoft’s Gemini Joker too, a vintage slot machine with 5 paylines and more than a few modern features.
While everything suggests a classic slot at first glance, the game’s guide will tell you that it’s anything but. Sure, the mechanics are similar to Vegas machines, but the medium variance, Stacked Symbols, and Multipliers are the modern features worth exploring. The two jokers play a large role too, playing the role of a Multiplier Wild.
The slot’s great math model and wins up to 1,700x the stake are more than enough to make it appealing to all kinds of players. You’ll be impressed with the graphics too – Betsoft truly outdid itself this time. If you'd like to try the game, snag yourself one of the generous slot bonuses from our top casino sites to give yourself some extra funds.


Gemini Joker is your regular 5x3 slot with familiar symbols. They’re all ripped straight from classic slot machines, featuring a range of fruits, golden gambling dice, a star, and the two jokers. The jokers are in a league of their own, both paying 25x for five and doubling any win they’re involved in.
The premium consists of the aforementioned fruits, with the star paying the most – 10x for five on a line. Instead of card royals, the low-paying symbol consists of a watermelon, a plum, and a pair of cherries.
Visually, this is one of Betsoft’s best works. The slot looks pretty sharp and we love the animations, especially when the joker on the left joins the show. The light-hearted music gives it a nice touch too, so overall, the audio-visual quality is pretty high.
You can spin the Gemini Joker on any Android and iOS device. It was developed on the HTML5 platform, so no need to download slot apps – the slot works great via a browser.
Set a bet to start playing – the default is $0.10, but you can bump it up in small increments all the way up to $10. Hit the Spin button and watch the reels roll with a nice animation. The base game works just like you expect it, with a few twists and turns.
For example, when the first two reels are filled with identical symbols, the Stacked Reel Respin feature comes into play. The triggering symbols are held in place while the other three reels respin.
The Wilds play a big role in the Gemini Joker slot too. They substitute for any symbol in winning combinations, but they also double any win they’re a part of. The great thing about this feature is that if multiple Wilds are part of the same win, their values are combined. So, for example, two joker Wilds pay x4, while four pay x8. Land the highest five and enjoy an x32 boost.
Now get ready – there is no Free Spins Round in the Gemini Joker slot. However, it’s not without an attractive bonus feature. When all reel positions are lined up with the same symbol, you get a spin on the Multiplier Wheel. It can award a multiplier between x2 and x10, which is then applied to your win.
And that’s it for the special features, but who could expect more out of a vintage slot?
Betsoft set the RTP of the Gemini Joker slot to 95.61%. It’s a medium variance slot game that offers a maximum winning potential of 1,700x your stake.
Gemini Joker is a great mix of vintage and modern slot games where both jokers play a Wild role. They can double any win they’re a part of, and instead of a Free Spins Round, you have a spin on the Multiplier Wheel. It’s exciting to play a game with 5 paylines but solid winning potential, so if you’re a fan of vintage slots, this one’s a keeper at the best online slot sites.
