Asgardian Stones by NetEnt is a 5-reel slot with 20 fixed paylines and a 5x4 grid layout. The game uses an avalanche mechanic, where winning symbols disappear and new symbols fall into place, allowing more wins from a single spin. Bets can be set from 0.20 to 200, and the demo version lets players play for free and practice before playing for real money.
The symbol set includes carved stone masks, letter symbols, and Wilds that substitute for regular paying symbols. Colossal symbols can appear in both the base game and free spins, with some covering 2x2 or 3x3 positions. Odin appears as a super Colossal symbol across a full 3x3 area, while crushed symbols may trigger larger payouts during avalanche sequences.
A Bonus Wheel can award instant cash prizes or free spins on the last three reels. Free Spins may be triggered for five, ten, or fifteen rounds, and wilds become colossal wilds during this feature. The wheel can reactivate in free spins, adding up to 25 more spins.
