The Runemakers DoubleMax™

The Runemakers DoubleMax™ by Yggdrasil is a high volatility video slot with a 6×6 grid that uses the cluster pays mechanic—wins are made when five or more matching symbols touch vertically or horizontally. Set in a mystical rune-filled forest, the theme leans heavily on ancient magic, runes, and northern mythology, with rich visuals of stones, gems, and ethereal ambient effects. The key feature is the DoubleMax™ mechanic, which doubles the win multiplier with every cascade (also referred to as a dropdown): each time you have a winning cluster and symbols tumble away, the multiplier increases, resetting only in the base game when no new wins are formed. During Free Spins, however, the multiplier does not reset, allowing it to climb continuously through chains of wins. The game includes Mystic Mystery symbols that can drop after a win and reveal the same regular symbol (excluding wilds and scatters), helping form larger clusters. Landing three or more scatter symbols triggers the Runemakers Free Spins mode, granting seven free spins, with the option via a gamble-minigame to increase that to eleven; a failed gamble forfeits the bonus. There’s also a Buy Bonus feature: players may pay a fixed multiple of their stake to immediately enter the Free Spins, either with the standard seven spins or the “Super Bonus” version awarding eleven spins. Wild symbols feature during cascades, adding between one and five wilds to empty spaces before the next batch of symbols falls. The game supports autoplay and offers a Bonus Boost option in the base game that increases the chance of landing scatters at the cost of higher stake, enhancing access to the free spins round.

You can try it for free in demo mode or play it for real money.
