If the relaxing vibe of a piano bar is what you require right now then why not join us we take a seat at a lamplit table, fire up a cigarette and check out this online slot from Random Logic/Section 8 Studios; it’s called Harmonium and it comes with an expanding wild feature and a progressive jackpot..

Harmonium is a five reel slot with three rows and ten fixed paylines; a gentle piano soundtrack accompanies your gameplay which takes place against a multicolour backdrop in which tiny musical notes float.

The standard symbols are all related to the theme and they are all musical notes of different colours – crotchets, quavers, semi-quavers and the like.

The wild is a glowing melange of notes which appears only on reels two, three and four and which will substitute for all others to help form winning combinations – it’s also the key to the main feature explained below.

Bonus Features

Expanding Wild

Any time a wild symbol lands on reels two, three and four it will expand to fill all positions on that particular reel, even if no wins are possible by doing so. You’ll then receive a free spin with that wild reel held in place; any further wilds landing will repeat the process until all three centre reels are completely wild with the obvious potential for some big wins.

Progressive Jackpot

The prize total shown above the reels can be won at random at any point but the chances of winning it are greater the higher the stakes used.

Verdict

Harmonium is a slot ideal for those who like to combine their reel spins with a calming experience accompanied by some relaxing music; just set the Autoplay and wait for those wilds to roll and just maybe the progressive jackpot. There’s and RTP of 96.32%.
