Based on the infamously furry episode, The Trouble with Tribbles, this five-reel, 25-payline slot takes all the retro charm of the original William Shatner-era Star Trek and turns it into a chaotic space adventure.

The Tribble Pinball feature literally fires Tribbles onto the screen, landing them in tubes that reward cash prizes, multipliers, and other goodies. Then there’s Win Warp, a feature that costs 10x your line bet but can randomly activate and throw in stacked wilds, multiplying wilds, or symbol upgrades.

In other words, pure space chaos—and we’re here for it.

Stargate SG1 – Fremantle

Another sci-fi classic turned slot, Stargate SG1 is based on the long-running TV series (which was based on the 1994 movie). Even if you’re not a Stargate superfan, this five-reel, 20-payline slot still has plenty to offer.

The symbols are all straight out of the series (J, Q, K, and A for the low-paying ones—obviously), but the real fun starts in the bonus round. Landing three scatters triggers up to 20 free spins, and each time you re-trigger the feature, the multiplier increases, stacking up to 5x your wins.

Basically, if you’ve ever dreamed of jumping through a Stargate and coming out richer, this is the slot for you.

Supernova – Quickspin

This slot doesn’t just look like something out of a sci-fi movie, it actually plays like one, too. The Supernova slot combines three traditional reels with two extra reels on the right—where you’ll either multiply your winnings or fall into a black hole of disappointment (yes, really).

Every time you hit a winning combination, the two extra reels spin—if you land multipliers, you boost your payout. If you land black holes, well… let’s just say space can be unforgiving.

There are no complicated bonus rounds, just a high-frequency, fast-paced game that makes you feel like you’re navigating a wormhole full of cash.

Money Mad Martians – Barcrest

If you want something more ridiculous, Money Mad Martians from Barcrest is the perfect blend of absurdity and solid slot gameplay.

Basically, if you’re here for fun, chaos, and the occasional massive win, the Money Mad Martians may be your new fave slot.
