Machine Gun Unicorn by Genesis – 97.1%

Machine Gun Unicorn Feature ImageMachine Gun Unicorn already wins us over with its hilarious visual style. It's a ridiculous premise for a slot and the name sells it way before the funny visuals do.

But Machine Gun Unicorn isn't all look. The slot has some incredibly fun gameplay combining:

  • Scatter/ Wild Symbols
  • Free Spins
  • Unlimited Triggers
  • Multipliers

All of this spread across a 5×3 reel layout, which Machine Gun Unicorn Big Wincontains 10 paylines. That may not sound like a huge number of paylines, so Genesis have balanced this with a low betting range of 1p-£25. That's a good spread by any standards. The slot also features a £25,000 max win and of course, the 2nd best RTP we've seen this year.

It's funny, it's fun and it's generous. You won't find more original and entertaining slots among the competition this year.

Starmania by NextGen – 97.87%

Starmania Wild SymbolsStarmania got a hard wrap from us when it first came around earlier this year. It has all the bells and whistles of a good slot.

5×3 reel layout, 10 paylines and wild/scatter features make it a competent slot on paper. It even has a 10p-£20 betting range, which although not the best, certainly matches most of the competition.

Where it stands out most is in it's RTP, something that we noted back then and are still praising now. It was the highest RTP of any slot we reviewed this year. All its other problems aside, this slot is still delivering on high and frequent payouts even at the end of the year. It is yet to be beaten.

If you're looking for a more standard slot experience, which has the ability for frequent payouts, then you couldn't do much worse than Starburst. It's at the top of our list and looks to stay there with an RTP like that.
