Every now and then, the industry will release a slot based on a familiar and popular theme that outdoes all others. That’s what the promising Slingshot Studios did with Spinny McWinnagin Loot Boost. Yes, it’s a mouthful, but so are the gameplay features. This Irish-themed bonanza impressed me on several levels, starting with the winning potential. It’s set at a decent 4,000x the bet, which isn’t much, but it’s distributed evenly and in a math model with medium variance.

This means you can expect varied wins from the base game to the bonus round. There’s a bonus round of free spins bonuses in addition to jackpots, as well as the Ultra Link & Win feature to top it off. More importantly, the slot is headlined by a charming leprechaun – Mr. McWinnagin himself who can wave his magic fingers and deliver incredible wins.

When you fire the slot up, you won’t find many differences between it and other Slingshot or Games Global slots. It has a 5x4 setup with 4 jackpots on the right side and the controls on the right. But you just need a few spins to see how it works and enjoy the magic this leprechaun has in his fingers.

Spinny McWinnagin Loot Boost is a 5x4 slot with medium variance. The Irish theme suits it perfectly. You’ll be playing in front of an enchanting Celtic landscape, with a lot of green and flying butterflies all over. The reels are dominated by the leprechaun as well as some other familiar symbols. These include a wooden mug of beer, his pipe, and a beautiful pocket watch.

With the controls on the right side, playing the slot is easy. You can check the guide and find out how the features work. It’s a slot that looks and feels perfect to play, with no complex features or visual elements. Thanks to this, I found it very easy to play on any device.

Before you start playing, you should check your bet. You can choose between 20c and $50 per spin. The default is set to $2 per spin, which is a bit high, in my opinion. The medium volatile math model pays for 3 or more matching symbols on the paylines. Spinny McWinnagin is the wild, substituting for other symbols in winning combinations while also paying decent returns.

When it comes to the symbols, the shamrock scatter pays the maximum – 100x for a combination of 5. The slot has plenty of features from the get-go, and I’ll cover them all below.

First up are the Power Stacks. I’ve seen this mechanic used in other Slingshot slots before. Any symbol can be randomly picked as a Power Stack on one or more reels. In the base game, only coins and regular symbols can be Power Stacked. During the bonus, the feature works on cash coins and wilds only.

The main feature in the Spinny McWinnagin Loot Boost slot is the Ultra Link & Win feature. Like most Hold & Win feature clones, it is triggered by 6 or more coins. You get 3 respins on a 5x4 reel set with 3 different modifiers:

• x2 multiplier
• Extra chance
• Unlock

The x2 multiplier boosts up to 4 coins with a doubling multiplier. The unlock coin activates an extra row, with up to 3 possible. Landing up to 3 extra chance coins prolongs the feature. A single extra chance coin awards an extra spin.

The prize coins award the corresponding jackpot. They can only land during this feature and in no other way. Cash coins can also land on the reels with values between 1x and 12x.

If you land 4- or 5-coin symbols on the reels in the base game, they’ll trigger the Ultra Link & Win max mode. It plays just like the regular one, except it comes with 3 additional unlocked rows.

Land 3 or more scatters to receive 10 free spins. The bonus round plays exactly like you expect it to, with no new features. The only difference is that all wilds and power coins are power stacked on the reels on each spin.

You can buy the free spins feature if you don’t want to wait to trigger it naturally. It costs 45x the bet. The bonus buy feature also works for the Ultra Link & Win regular and Max features, costing 45x and 80x, respectively.

Spinny McWinnagin Loot Boost is a pretty fun slot game. It looks amazing and plays great, thanks to the number of features. This is one of those rare real money slots where I hit better wins in the base game with the special features instead of the bonus round. I tried the free spins via the bonus buy feature but wasn’t impressed by it.

On the other hand, I was impressed by the Link & Win feature, and especially the doubling multiplier. I hit a few wins worth a hundred times my stake (which was $1 btw) and did that in just around a dozen spins. It’s a great feature that can turn your fortune around if you have Spinny McWinnagin on your side. I certainly did.

The Spinny McWinnagin Loot Boost slot RTP is set at 96.05%, which is great for a medium volatile slot game. It pays a maximum of 4,000x per spin.

Spinny McWinnagin Loot Boost doesn’t have the most innovative theme or gameplay features, but it’s rewarding and fun to play. It’s just the jolt of energy this slot theme needed. How could you not like a leprechaun/Irish-themed slot with jackpots, a Hold & Win bonus, and a free spins round? Spinny is as magical as you can expect a leprechaun to be, so it’s more than worth a few spins.

If you’re into this particular theme, try Slinghots’ other Irish slot – Leprechaun Links. You can also go for Links of Fire, which uses the Link & Win feature, too.
