Rules and Gameplay

Dive into the mystical world of alchemy with Endorphina’s Magnum Opus, a slot game that combines ancient secrets with modern slot mechanics. With its 3×3 grid and 5 adjustable paylines, players have the autonomy to set their betting strategy, choosing anything from $0.01 to $50 per spin. The gameplay is straightforward yet engaging, encouraging players to match thematic symbols across the paylines to win. Adjusting the number of paylines and bet size is simple, allowing for a personalized gaming experience tailored to each player’s preference and strategy.

Bonus Features

Magnum Opus entices players with its array of captivating bonus features:

  • Golden Elixir Bonus Game: A thrilling feature that is activated by landing nine identical medium-value symbols. Players are then whisked away to an alchemist’s lab, where they select elements to attempt creating precious metals, each successful attempt increasing their multiplier.
  • Gamble Feature: Offering players a chance to double their winnings, this feature allows for a card selection gamble post any win. Choosing a card higher than the dealer’s can potentially double the win, adding an extra layer of excitement and opportunity for risk-takers.

These bonus features add a rich layer of depth and engagement to the game, providing players with ample opportunities to increase their winnings through strategy and luck.


The symbols within Magnum Opus are intricately designed to reflect the alchemical theme:

  • Low-Value Symbol: The Pentagram, offering a modest 1x multiplier for three matches.
  • Medium-Value Symbols: The four elements of Nature (Air, Water, Fire, Earth), each granting an 8x multiplier.
  • High-Value Symbols: Precious metals like Copper, Silver, and Gold, with multipliers of 12x, 40x, and 150x respectively.

Even without traditional wilds or scatters, these symbols bring a unique gameplay dynamic, making every spin a chance to delve deeper into the alchemical mystery.


Payouts in Magnum Opus are as rewarding as they are mystical. Here’s a glance at what players can expect for aligning three of a kind:

Symbol Payout
Lion 7,500x
Crescent Moon 2,000x
Magic Eye/Fire/Water/Air 400x
Triangle in Circle 50x

This table highlights the game’s potential for substantial rewards, making it a lucrative choice for players seeking both enjoyment and the chance for significant wins.


With 5 adjustable paylines, Magnum Opus offers players the flexibility to tailor their betting strategy. Wins are counted from left to right, starting from the leftmost reel, and only the highest win per payline is paid out. This setup allows for strategic play, as participants can decide how many lines to activate, balancing the thrill of potential wins against the strategy of payline selection.
