Asgardian Stones is a NetEnt slot built around Norse mythology, released in February 2018. It runs on five reels with 20 fixed paylines and uses a cascading Avalanche mechanic rather than traditional spinning reels. The RTP is 96.31% - sitting just above the industry average - with low-to-medium volatility and a maximum win of 1,000x your stake.
Game Basics
The grid is five reels by three rows with 20 fixed paylines. Wins pay from left to right, requiring three or more matching symbols starting from the leftmost reel. Bets range from £0.20 to £200 per spin, making it accessible for casual players while still offering reasonable headroom for higher stakes.
The theme leans into Norse mythology with stone-carved deity faces as premium symbols alongside standard playing-card royals (A, K, Q). The gold W acts as the wild, substituting for all symbols except the Bonus Wheel. Symbols drop from above rather than spinning, which ties directly into the core Avalanche mechanic.
RTP and Volatility
The 96.31% RTP is slightly above average for the genre and is consistent across both the base game and free spins. Low-to-medium volatility means you can expect a reasonable hit frequency - NetEnt quotes 20.1% - with a mix of smaller regular wins and occasional bigger payouts from the feature mechanics. This slot does not carry a progressive jackpot; the maximum fixed win is capped at 1,000x your stake, which at the maximum bet of £200 equates to £200,000.
Avalanche Feature
The Avalanche is the engine that drives Asgardian Stones. When symbols land in a winning combination, they explode and disappear, and new symbols cascade down to fill the gaps. If those new symbols form another win, the process repeats - and keeps repeating until no new winning combination lands.
Each consecutive avalanche within a single spin can build on wins from the previous one, meaning a single spin can deliver multiple payouts before the round ends. The Colossal Crush mechanic adds another layer to this: when a colossal symbol lands with empty space below it, it can crush additional rows beneath it, awarding a win multiplier of up to 4x for each row crushed.
Colossal Symbols
Any symbol in the game - except the wild - can appear as a Colossal version. These are oversized 2x2 or 3x3 blocks that occupy multiple positions on the reels. Only one colossal symbol can appear at a time, but its size means it can cover a significant portion of the grid.
Colossal symbols work especially well with the Avalanche mechanic. A 3x3 colossal symbol landing on the right positions can contribute to several winning combinations simultaneously. They also appear during free spins, where the wild can become colossal.
Bonus Wheel Feature
The Bonus Wheel is triggered when a 3x3 symbol block lands across the final three reels (reels three, four, and five). The wheel itself has eight sections offering either coin wins or free spins - up to 15 free spins per trigger. One important detail: the Bonus Wheel is not cleared after it awards its prize. Because it stays on the reels, no Avalanche follows its evaluation, which breaks the cascade chain but delivers an immediate guaranteed payout.
The Bonus Wheel can retrigger during free spins, with a maximum of three retriggers and up to 25 total free spins in a single bonus round.
Free Spins
Free spins activate once the Bonus Wheel lands on a free spins award. During this feature, wilds can appear as colossal 3x3 blocks. When a colossal wild contributes to a winning combination, it splits into individual 1x1 wild symbols - which stay on the reels and can contribute to further wins in subsequent avalanches within the same free spin.
The combination of colossal wilds splitting into standard wilds and the ongoing Avalanche mechanic means free spins rounds have genuine potential to chain together multiple wins from a single spin trigger.
How to Play
Set your bet using the stake controls - the minimum is £0.20 and the maximum is £200. All 20 paylines are fixed, so you cannot adjust the number of lines active. Press spin (or use autoplay) and the symbols drop into place. The Avalanche mechanic takes over automatically if wins land, so there is nothing to do mid-spin.
The Bonus Wheel triggers naturally when the 3x3 wheel block appears on reels three through five. Free spins begin immediately after the wheel is evaluated. Retriggers during free spins are automatic if the wheel appears again.
Mobile
NetEnt developed Asgardian Stones with mobile in mind from the outset. The five-reel layout scales cleanly to portrait and landscape on phones and tablets. The touch controls handle the dropped-symbol animation of the Avalanche mechanic well, and the colossal symbol overlays remain clear on smaller screens. No separate app is needed - the game runs in your browser.
Who Is Asgardian Stones For?
Low-to-medium volatility with a 20.1% hit frequency makes Asgardian Stones a reasonable fit for players who want a mix of base-game activity and the occasional feature round, without the long dry spells of high-variance titles. The Avalanche mechanic adds some natural session rhythm - wins can build across cascades - without requiring huge swings to access the best payouts.
The 96.31% RTP is solid, and the 1,000x maximum win is achievable through the Colossal Crush and free spins combination, though it requires the right conditions. If you want a Norse mythology slot with a more active feature set than something like standard NetEnt fare, Asgardian Stones is worth a session.
