Magnum Opus

Magnum Opus by Endorphina is a 3-reel, 3-row slot with 5 paylines and a 96.01% RTP. Wins are paid for matching combinations on adjacent reels from the leftmost reel, with only the highest win counted on each enabled payline. The game uses a theme based on alchemy and the search for the Golden Elixir.

The main feature is the Golden Elixir Bonus Game, triggered when 9 symbols of the same natural element land on the reels. In the bonus round, players enter an alchemist’s laboratory and can multiply winnings by 2, 4, or 8, depending on whether copper, silver, or gold is reached. The sequence must progress in order, and if the experiment fails, the bonus ends.

A classic Risk game is also included, allowing players to double winnings up to 10 times. The demo version is available to play for free, which lets users practice before playing for real money and review the paytable, bonus rules, and symbol combinations in advance.
