The Runemakers DoubleMax™

Yggdrasil presents The Runemakers DoubleMax™, a video slot characterized by high volatility and a 6×6 grid that employs a cluster pays mechanic. Wins occur when five or more matching symbols connect either vertically or horizontally. The setting is a mystical forest filled with runes, drawing inspiration from ancient magic and northern mythology, featuring stunning visuals of gems, stones, and enchanting ambient effects. A standout aspect of the game is the DoubleMax™ mechanic, which enhances the win multiplier with each cascade, or dropdown; whenever a winning cluster is formed and symbols disappear, the multiplier increases, but it resets only in the base game when no new wins occur. In Free Spins, the multiplier continues to grow without resetting, allowing for an ongoing accumulation through consecutive wins. Mystic Mystery symbols may appear after a win, revealing a regular symbol (excluding wilds and scatters) to help create larger clusters. Triggering the Runemakers Free Spins mode requires landing three or more scatter symbols, which awards seven free spins, with a gamble-minigame option to increase that to eleven spins; however, failing the gamble results in losing the bonus. Additionally, a Buy Bonus feature allows players to pay a fixed multiple of their stake to access Free Spins immediately, either with the standard seven spins or the "Super Bonus" version that grants eleven spins. During cascades, wild symbols can be added, placing between one and five wilds in empty spaces before the next symbols drop. The game also includes autoplay functionality and a Bonus Boost option in the base game, which raises the likelihood of landing scatters in exchange for a higher stake, facilitating entry into the free spins round.
