Loki's Descendants — Bonus Features
Loki's Descendants runs three named features and a tiered free-spins engine. Here's how the Serpent, Fenrir, and Hel actually stack.
How Each Feature Pays
Trigger rules, multiplier ceilings and where each one is worth your money. Unclear how a feature fires mid-round? Our Loki's Descendants how-to-play guide walks every step.
Serpent Feature
How to Trigger
Random, in any spin. The Serpent can be triggered once, twice or three times within the same spin.
What Happens
On the first trigger the Serpent blows 3 Wilds diagonally from the 2nd reel to the 4th, starting from its mouth. Those Wilds substitute for every paying symbol. A second trigger in the same spin awards a multiplier of x3, x5 or x10, which is added to the three Wilds already on the grid. A third trigger awards another x3, x5 or x10 — and this one multiplies the first, rather than adding to it. The Serpent may also fire alongside Fenrir and Hel in the same spin.
Multipliers
Second trigger: x3, x5 or x10. Third trigger: a further x3, x5 or x10 applied on top of the second, so the highest combination Red Tiger publishes is x10 multiplied by x10.
Variants
Inside Free Spins at least one of the three children fires every spin; in Super Spins a feature fires at least twice per spin and in Monster Spins three times, which raises how often the Serpent reaches its second and third trigger.
Strategy
It's a random event, so there's nothing to chase — bet flat. What's worth knowing is that the Serpent only becomes a multiplier feature from its second trigger onwards. A single trigger is three Wilds and nothing more, which is why the spins tiers matter: they're the only place where repeat activations are guaranteed.
| Trigger | Random, 1-3x per spin |
| First trigger | 3 diagonal Wilds, reels 2-4 |
| Second trigger | x3 / x5 / x10 added |
| Third trigger | x3 / x5 / x10, multiplied |
| Parallel | Yes, with Fenrir and Hel |
Fenrir Feature
How to Trigger
Random, in any spin. Like the Serpent, Fenrir can be triggered once, twice or three times in the same spin.
What Happens
Each trigger eats a different band of the paytable. The first removes every Junior symbol — A, K, Q, J and 10. The second removes Beer and Shield. The third removes Spear. Once Fenrir is finished, new symbols fall from the top into the empty positions, and only symbols he did not remove plus Wilds are allowed to fall. Three triggers therefore leave a grid built from the top of the paytable and Wilds only.
Multipliers
None directly. Fenrir changes what can occupy the grid, and the value shows up in what falls in afterwards rather than in a multiplier of its own.
Variants
Fenrir may be triggered in parallel with the Serpent, and with Hel. In Monster Spins, where a feature activates three times per spin, a full three-stage clear-out is far more reachable than it is in the base game.
Strategy
Treat Fenrir as the setup rather than the payout. One trigger only clears the card royals, which on a 432-ways grid is a modest improvement. The version worth wanting is the second and third trigger inside a Super or Monster round, because that's when the refill pool has been narrowed to premiums and Wilds.
| Trigger | Random, 1-3x per spin |
| First trigger | Removes A, K, Q, J, 10 |
| Second trigger | Removes Beer and Shield |
| Third trigger | Removes Spear |
| Refill | Non-removed symbols and Wilds |
Hel Feature
How to Trigger
Random, in any spin — and like her brothers, up to three separate times in one.
What Happens
Hel's knife works on the winning symbols themselves rather than on the payout figure. The first trigger halves each winning symbol into twins. The second turns all winning symbols into triples. The third turns them into quadruples. Because the game pays 432 ways, duplicating a symbol that is already part of a win multiplies the number of ways that win counts on — which is where the payout growth comes from.
Multipliers
Published as symbol duplication, not as a x-value: twins on the first trigger, triples on the second, quadruples on the third.
Variants
Hel may be triggered in parallel with the Serpent and/or Fenrir. The most productive pairing is a Fenrir-cleared grid feeding premium symbols that Hel then quadruples.
Strategy
Hel needs a win on screen to act on — she duplicates winning symbols, so a dead spin stays dead. That's the argument for the Super and Monster tiers, and for the 20x random-feature buy: Hel's output scales with whatever's already paying.
| Trigger | Random, 1-3x per spin |
| First trigger | Winning symbols become twins |
| Second trigger | Triples |
| Third trigger | Quadruples |
| Parallel | Yes, with Serpent and Fenrir |
Free Spins, Super Spins & Monster Spins
How to Trigger
Scatters land on the 1st, 3rd and 5th reels. Three Free Spins scatters in the base game start 7 Free Spins. Two Free Spins scatters plus one Super Spins scatter start 7 Super Spins. Two Super Spins scatters plus one Free Spins scatter start 7 Monster Spins.
What Happens
The three tiers differ by how hard the children work. In Free Spins at least one of the Serpent, Fenrir and Hel is activated during every spin. In Super Spins at least one of them is activated at least twice per spin. In Monster Spins at least one is activated three times per spin. Landing three Free Spins scatters inside a round upgrades the rest of it to the next tier and awards 7 additional spins. Super Spins symbols cannot land during Free Spins, Super Spins or Monster Spins, so the upgrade path always runs through the Free Spins scatter.
Multipliers
No multiplier of its own. The tier sets how many child activations you are guaranteed per spin, and the Serpent and Hel supply the scaling from there.
Variants
Three tiers of 7 spins each, plus two published routes straight to the cap: three Super Spins scatters in the base game award 20,000x immediately, and three Free Spins scatters during Monster Spins upgrade the current win to 20,000x and end the feature.
Strategy
Tier beats spin count. Seven spins is seven spins at every level — what changes is whether you get one activation per spin or three, and that's the entire difference between a modest round and a run at the cap. If a round does hit 20,000x it ends immediately and any remaining spins are forfeited, so don't bank on anything after it.
| Scatter reels | 1st, 3rd and 5th |
| Spins per tier | 7 |
| Free Spins | 1 activation per spin |
| Super Spins | 2 activations per spin |
| Monster Spins | 3 activations per spin |
Feature Buy
How to Trigger
Bought from the game menu, where the operator and jurisdiction allow it.
What Happens
Red Tiger publishes three purchases. For 20x the stake you are guaranteed one random trigger of the Serpent, Fenrir or Hel on that spin. For 75x you are guaranteed to land the three Free Spins symbols and enter the bonus round. For 500x you are guaranteed to land the scatter combination for Super Spins or Monster Spins — one or two Super Spins symbols with two or one Free Spins symbols respectively.
Multipliers
Identical to the naturally triggered version of whatever you bought; buying changes the entry, not the maths inside.
Variants
Three price points: 20x random feature, 75x Free Spins, 500x Super or Monster Spins. Several markets, the UK among them, block feature buys entirely.
Strategy
The 500x tier is the only one that buys the guaranteed repeat activations, which is where the published max win actually lives — the 75x Free Spins buy still only guarantees one child per spin. Red Tiger doesn't publish a separate RTP for any of the three, so treat the price as the price and nothing more.
