Spinny McWinnagin Loot Boost: Slot Overview
Leprechaun-themed slots may not top many players’ must-play lists, but if that’s your kind of thing, this one should fit the bill. Spinny McWinnagin Loot Boost comes from Games Global partner Slingshot Studios—whether you’re grateful or rolling your eyes is up to you. For Spinny, Slingshot Studios has essentially replicated Loot Boost, which landed around 4 months earlier, meaning the same characters and mechanics are back again, only this time dressed up with a leprechaun makeover to freshen the look.
If you’re thinking, “Wait, hasn’t Slingshot Studios already done a leprechaun reskin?”—yes, they have. Previously it was Leprechaun Links, itself a copy of Game of Thrones Power Stacks and Links of Ra. The funny (or concerning) part is the studio has more or less lifted the forest backdrop (and other elements) from Leprechaun Links and dropped it into Spinny McWinnagin Loot Boost. Sure, there’s been a general visual polish, but it’s largely the same package. Make of that what you will: impressive efficiency or plain old corner-cutting. It feels closer to the latter. In short, Spinny McWinnagin Loot Boost is basically Leprechaun Links and Loot Boost rolled into one.

Much like its slightly earlier sibling, Spinny McWinnagin Loot Boost is a medium volatile slot with a default return to player of 96.05%. On this setup, the hit rate sits at 33.71%, and players can choose stakes from 20 c to $/€50 per spin. In terms of mechanics, Spinny McWinnagin Loot Boost runs on a 5 reel, 40 payline layout, set in a woodland scene where butterflies drift around the reels.
The paytable is packed with classic leprechaun-themed items, starting with clubs, diamonds, hearts, and spades, followed by a pipe, a harp, a beer mug, a pouch of coins, and a pocket watch. Hitting a 5 OAK with these symbols returns 1.8 to 8 times the bet. Mr McWinnagin appears on the wild symbol and can land on all reels. Wilds replace all standard pay symbols, and landing 5 of them on a payline awards 10 times the bet.
Spinny McWinnagin Loot Boost: Slot Features

Spinny McWinnagin Loot Boost’s features are Power Stacks, the Ultra Link&Win, the Ultra Link&Win feature in Max Mode, Ultra Link&Win Booster Coins, Prize Coins, Cash Coins, Free Spins, and a bonus buy.
Power Stacks
In the base game, all symbols apart from scatters and wilds can be Power Stacked, while during free spins only wild or Coin symbols may be Power Stacked. Power Stacked basically means the symbols are stacked.
Ultra Link&Win Feature
Hitting at least 6 Coin symbols activates the Ultra Link&Win feature, awarding 3 free respins, with the triggering Coins held in place while the remaining positions respin. Any new Coins that land are also held, and the respin counter resets to 3. The feature ends when no further Coins appear or when all reel spots are filled. Any Cash Coins or Prize Coins collected are paid out. Ultra Link&Win can be triggered in the base game or during free spins.
Ultra Link&Win Feature in Max Mode
Landing 4 or 5 Coins in the base game increments the Max Mode Ultra Link&Win meter. If you trigger Ultra Link&Win with the meter filled, you enter the feature in Max Mode. In this mode, 3 additional active rows are added to the reels. In addition, entering free spins with a full meter guarantees that every Ultra Link&Win trigger happens in Max Mode.
Ultra Link&Win Booster Coins
Ultra Link&Win Booster Coins can modify how the Ultra Link&Win feature plays out:
- 2x Multiplier Booster Coin – randomly doubles up to 4 Cash Coins.
- Unlock Booster Coin – 1 Unlock Booster Coin activates an additional row. Up to 3 additional rows may be activated.
- Extra Chance Booster Coin – landing up to 3 Extra Chance Booster Coins lengthens the Ultra Link&Win feature. 1 Extra Chance Booster Coin awards a free respin.
Prize Coins and Cash Coins
Prize Coins are the Mini, Minor, Major, and Grand Coins, valued at 40x, 100x, 500x, or 1,000x the bet, respectively. Cash Coins can land with values ranging from 1 to 12 times the bet.
Free Spins
Landing 3, 4, or 5 scatters awards 10 free spins along with a cash prize of 1x, 10x, or 100x the bet, respectively. During the feature, wilds or Coin symbols are Power Stacked on each free spin in the round.
Buy Feature
With the Buy Feature, players can buy free spins for 45x the bet, Ultra Link&Win for 45x the bet, or Max Mode Ultra Link&Win for 80 times the bet.

Spinny McWinnagin Loot Boost: Slot Verdict
In a business where “re-” everything (recycling, reusing, reskinning, and so on) is standard practice, Spinny McWinnagin Loot Boost still manages to be noticeable. As noted earlier, leprechaun-flavoured clones probably aren’t high on most people’s wish lists, but they certainly seem to be on Slingshot Studios’. That impression comes from looking at Leprechaun Links previously and now Spinny McWinnagin Loot Boost. A lot of Spinny McWinnagin Loot Boost’s visuals are even the same as those seen in Leprechaun Links, albeit with some touch-ups. As hinted above, it feels like two older releases stitched together into one creatively empty offering.
Because the gameplay is unchanged, there’s not much to say that wasn’t already covered in Loot Boost. And if Slingshot Studios can’t be bothered to build something new, it’s hard to expect players to get excited about it. Apologies if that sounds a bit grumpy. The bottom line is that anyone who enjoys Games Global family-style features will likely be fine with the familiar set of extras in Spinny McWinnagin Loot Boost as well. Hold & wins and static jackpots are popular, widely used mechanics, and they’re all present here in the forest setting. Also on offer in Spinny McWinnagin Loot Boost is a maximum win of 4,000x. It’s a decent target in what is, at best, a decent slot—and not Slingshot Studios’ most original moment.
