About this Slot
Magnum Archanum is a fantasy-themed alchemy slot from Energy8 with an RTP of 96.25%, high volatility and a maximum win of 20,000x.
Wins form geometric clusters rather than traditional lines. Valid winning shapes are the triad, line, quaternio, sigillum, hexagram and Sephirot. Symbols can belong to multiple shapes at once, allowing a single symbol to contribute to several wins in a single spin. When symbols win, they dissolve and new ones cascade down to fill the gaps.
The sigillum shape converts one random low-tier symbol into a mid-tier symbol. The hexagram upgrades all low-tier symbols to mid-tier and all mid-tier symbols to high-tier within the winning cluster. The Sephirot shape converts all low-tier symbols on the board to mid-tier and all mid-tier symbols to high-tier.
The Ouroboros Wild substitutes for any regular symbol to complete wins. Four or more Lapis Scatter symbols trigger the Free Spins round, which begins in the Nigredo stage. A bonus-wide counter runs throughout the entire free spin session. Higher counts of Lapis scatters at the trigger award longer free spin sessions. Landing three or more Lapis scatters within a single spin grants an additional 2 spins.
Six buy options let players enter the bonus directly. Ouroboros costs 6x the bet, Catalyst costs 30x, Standard Bonus costs 100x, Adept Bonus costs 250x, Master Bonus costs 500x and Transmutation costs 1,000x the bet.
