How Magnum Opus works

This 3-reel, 3-row slot has 5 paylines. Matching symbols must be on a payline on adjacent reels, starting from the leftmost.

Golden Elixir Bonus Game

When 9 symbols of the same element appear on the reels, the bonus starts in the alchemist's laboratory. You can multiply your winnings by 2, 4 and 8 times by making copper, silver and gold in turn. You cannot get gold right away: copper and silver come first. If an experiment fails, the bonus ends. Only the last activated multiplier is applied.

Top symbols

Three lions award 150x the base bet and three moons pay 40x.

What to look for in the demo

Count how often you get past copper. Each step is a separate risk.
