Theme, Graphics and Soundtrack

What a great game this is! Although it’s merely a brick wall, the set helps to create the feeling of a laboratory with its eerie lighting and small blinking objects. The reels and symbols are really clever, whereas the plucked violins on the soundtrack are enigmatic and there are slightly chilling choral voices that occasionally interrupt spins. It looks so good that one cannot help but like it.

Magnum Opus Bonus Features

Golden Elixir Bonus Game

If nine of any alchemical kind land on the reels (Earth, Fire, Water or Air), the Golden Elixir Bonus game is activated. In the feature round, you are taken to Alchemist’s Laboratory where you will make him create gold.

The Alchemist will give you the following bonus to your nine-of-a-kind wins if you happen to win.

Making copper (cuprum) will multiply by 2x. Making silver (argentum) will multiply by 4s. Making gold (aurum) will multiply by 8x.

It is impossible to make gold on your first attempt. To do that you have to convert copper and then silver. To start the experiment, choose an alchemical element on the right-hand side.

When your experiment goes well, you are given a medal and can proceed to the next stage by supplementing your already created metal with one of the rest alchemy elements. However, in case it is unsuccessful, the bonus round gets terminated.

Cumulative bonus game wins are not allowed in the system. In case of a 9-of-a-kind win, only the last multiplier applied will be taken into consideration. It will be impossible to re-trigger the feature and get another bonus game.

Gamble Feature

This will increase your winning possibilities up to times ten. Select one card from the four dealt facedown. If you defeat the dealer’s card, your win is doubled and you can have another try. Whenever the dealer wins at any stage, the game stops and all your winnings are gone. Any close card may be higher or lower than those of a dealer. The cards can be seen in various rounds again and again in order to make you complete this level. All other cards are ranked below the joker irrespective of their values. In such instances, none of them wins because none loses as well as you can play once more on this one play option. Should you wish not to risk, click on Take Win button instead. You can do it before starting or anytime throughout a round feature.

Magnum Opus Review: Our Verdict

This is a good game for beginners. The only bad thing about it is that the automatic mode is too simple, which means you cannot set it to stop on any win; so if you are not alert enough and miss stopping the reels in time, you lose your chance to double your winnings. Apart from this aspect, we enjoyed ourselves quite a bit.
