Ascend to the mythical halls of Asgard in Gates of Valhalla, a Norse-themed slot featuring a 5x5 grid with 10 paylines that pay both ways. Winning combinations trigger a tumble feature, removing winning symbols and allowing new ones to drop, creating opportunities for successive wins. Wild symbols are central to the action; they not only substitute for other symbols but also roam across the reels after a win, applying an increasing multiplier with each move until they exit the grid. Landing three or more scatter symbols unlocks the Free Spins feature, providing a series of spins where the roaming wilds and their escalating multipliers are even more prominent, promising epic payouts from the gods.
