Asgardian Stones

NetEnt frames Asgardian Stones around Nordic mythology, running a 5x3 grid with 20 fixed paylines and a reaction-based win system in place of standard spinning reels — winning symbols are removed from the grid and replaced by new ones falling into their place, continuing until no further wins appear. Wins pay when three or more matching symbols land in consecutive columns starting from the left.

Five coloured stone-face symbols make up the premium end of the paytable, topped by a red stone face as the highest payer, while A, K and Q card values cover the low end; a wild substitutes for any regular symbol on the grid.

Any symbol can also appear as a Colossal version, filling a 2x2 or 3x3 block of positions, though only one Colossal symbol can occupy the grid at a time and the wild only takes this form during the free spins round. A Colossal Crush effect can then break apart the symbols sitting beneath a Colossal block at random, and each row crushed this way adds a multiplier of x2 to x4 onto the win that follows it.

A 3x3 Bonus Wheel symbol block can land across the final three reels in both the base game and the free spins, sometimes only partially in view, and whichever of its eight sections fall within the visible play area pay out — three of the sections award five free spins each, while the rest hand out coin prizes instead, so a triggering spin can just as easily miss the bonus entirely as start it with up to fifteen free spins.

During free spins, the wild symbol takes its Colossal form, and if a Colossal wild forms part of a winning combination it splits into individual 1x1 wilds across the affected positions. The Bonus Wheel can reactivate up to three further times within the round, adding as many as twenty-five additional free spins in total.

Asgardian Stones carries a 96.31% RTP, low-to-medium volatility, a 20.1% hit frequency and bets from 0.20 to 200 per spin, with a maximum win of 2,400x the stake.
