Shields of Gold: Valkyrie Hold and Win — Viking Wins with a Twist

Release Date: September 2025

Developer: Booming Games

RTP: 95.5%

Volatility: High

It’s obvious from the time you open this game that Booming Games isn’t playing around with Shields of Gold: Valkyrie Hold and Win. It takes the usual Hold and Win format and turns it into something undeniably sharper, faster, and a bit more tactical. The Viking theme isn’t new, of course, but this game doesn’t just slap on a horned helmet and call it a day. You’ve got layered features, animated shields, transforming wilds, and free spins that demand decisions.

It’s slick, it’s aggressive, and it’s meant for players who enjoy a bit of tension with every spin.

The Viking Setup and Hit Mechanics

This is a 5×3 slot with 20 fixed paylines. Up front, it’s pretty basic and simple. There are no changes and no toggles. Just straight-up Viking gameplay where every line stays active. The theme leans on traditional Norse myth and heavy armor, but it’s the mechanics that make this slot interesting for all types of gamers.

Hit frequency is set at 26.3%, so roughly 1 in 4 spins should give you something to add to your bankroll. Free spins are a different story, though. Those are harder to come by, dropping once every 76.6 spins on average. And, as you’d expect, that’s where the high volatility kicks in — not a slot for casual sit-and-spin fans.

The total RTP comes in at 95.5%, but it’s a split between base game at 43.8% and free spins at 51.7%. So yes, the money is hiding in the bonus rounds.

The max win sits at just 2,200x, which isn’t huge, but it’s not trying to blow the roof off with 10,000x nonsense. It’s aiming for solid, hit-and-move wins that feel achievable. The high rollers might be turned off by this.

Wild Transforms and Shields — The Real Core

This isn’t your basic wild symbol setup. Shields of Gold: Valkyrie uses something called Wild Transform, and it’s where the game starts to show its teeth.

Here’s how this unique mechanic plays out. First, you land shields on reels 1 and 2. Then, hit wilds on reels 3, 4, or 5. That triggers the Wild Transform feature. When it hits, things shift quickly, and a few key events unfold.

Every wild on the screen becomes a shield.

Shields then either give you instant coin prizes (Coin Collection) or trigger a Hold and Win Respin.

Sure, you don’t know which one you’ll get until it plays out, but we find that that’s part of the appeal. It keeps tension high.

Shield values range from 1x to 20x, but they can also hit the usual jackpot symbols.

Mini: 10x

Minor: 50x

Major: 100x

Grand: 1000x

Only reels 1 and 2 get base shield symbols, but Wild Transform can drop them on all reels. And when that happens, especially with high-value shields, it changes the tone of the entire round, and you know it.

Hold and Win Respin System

If one of your shields flips into a Respin symbol, then you get pulled into the Hold and Win Respin mode.

This is exactly what it sounds like as it’s the classic Hold and Win mechanic — but done with some tight, no-fluff pacing.

Shields lock in place.

You get 3 respins.

Only blank symbols or new shields can land.

Every new shield resets the spin counter back to 3.

It ends when you run out of respins or the board fills up.

This mode is what really drives the chase for the Grand prize. It’s lean, and it focuses on shield stacking, which keeps you visually locked in. There are no distracting animations or drawn-out sequences as this game gets to the point.

Free Spins with Tactical Choice

Triggering the Free Spins takes 3 bonus ship symbols — and they’ve got to land on reels 1, 3, and 5. That unlocks a feature that doesn’t just start rolling. It asks you to make a decision first, so you have a chance to somewhat control the outcome.

6 Free Spins: Better chance of hitting shields on reels 1 and 2.

8 Free Spins: Higher odds of getting wilds on reel 5.

This isn’t just cosmetic, as it changes the rhythm of the round.

Don’t just look at how many spins you get because it’s a little deeper than that. If you’re shield-hunting and want to aim for Wild Transform features, the 6-spin option is easily the smarter bet. If you want broader wild coverage and longer volatility play, the 8-spin route makes more sense.

Also worth noting is that you can retrigger the free spins during the bonus. Just land 3 more bonus ships and the round resets with whatever option you picked the first time — unfortunately, no swaps allowed mid-round.

Base Game Options — Golden Spin and Bonus Buy

Like most of the big developers, they’ve given you 2 tools in your belt if you’re the type who doesn’t want to wait around.

Golden Spin Toggle. Flip it on to boost your bet by 25%. This increases your chances of triggering the Free Spins or Hold and Win features. It’s not a wild gimmick — just a quiet, paid edge. However, it doesn’t affect how much you win. Winnings are still calculated off the base bet, not the boosted spin amount.

Play Bonus Buy. You get 2 choices with this bonus buy. The Mystery Bonus costs 75x your stake and gives you a random bonus, but the Special Bonus costs 100x and guarantees a specific bonus feature.

Plenty of choice to choose your own destiny. You’ll want to use these if you’re chasing volatility and don’t want to grind. But even without them, the game still feeds you a decent amount of Wild Transform hits in the base mode.

Payout Structure and Prize Factor

This slot doesn’t live and die on line hits. In fact, the max per line is only 5x — which isn’t really anything to get excited about. But that’s because the real money comes from building layers through shield values, jackpots, and multipliers.

Everything pivots around collecting coin values through shields, triggering jackpots from shield symbols, and hitting Wild Transform and hoping it flips into a respin round.

What you get is a build-and-burst model. Slow stacking of values, then quick shots of payout when the right combo hits the reels.

It’s not one of those slots where the screen explodes every 5 seconds. While that’s exciting to some, this one takes a little patience but rewards you with more meaningful triggers.

Ready for War? Load Up Shields of Gold: Valkyrie

Shields of Gold: Valkyrie Hold and Win is not messing around, and that’s what we love about it. It delivers a tight Viking theme with actual gameplay depth. The Wild Transform mechanic gives it a sharper edge than most of its genre rivals, and the ability to choose your free spin mode puts strategy into the hands of the player.

If you like Hold and Win games but find most of them too passive or repetitive, this one’s definitely worth your time. It trims the fat, turns up the tension, and throws in some solid design work to keep it fresh.

Forget the gimmicks of some of the other games on the market. If you’re in it for jackpots, decisions, and shield-stacking satisfaction — this is your next spin.
