Imperial Opera is a 5 reel, 20 payline slot which is set in an exquisite Asian themed opera house – it can be played from 20p to £100 a spin on desktop, mobile and tablet devices. It comes with quite a few bonus features where you’ll benefit from stacks, Mega Symbols, adjacent reels showing the same symbol, wild reels and free spins with locked wilds and Mega Symbols.

With an elaborate look, Imperial Opera has an Asian theme and takes you an opera house – with dark red reels, symbols on the reels include A, K, Q, J and 10 playing cards decorated with delicate flowers and 3 Asian characters. The princess is the wild and replaces all symbols bar the scatter – 5 of them on a payline will give you 25 times your stake.

When it comes to bonus features, there’s a few – you have the Showcase feature which is available on each spin. 1 symbol, bar the scatter, is randomly chosen with stacks of that symbol added to the reels. Furthermore, all character symbols appear as Mega Symbols to help you win more.

There is also a Harmony feature which is randomly activated in the base game – either 2 or 3 adjacent reels are chosen randomly and spin to show the same symbols. The Crescendo feature is also randomly triggered with 1 or 2 randomly chosen reels displaying wilds for 1 or 2 wild reels – this also applies in the base game only.

When the Harmony feature is in play, you can see the large Free Spins scatter which is 3×3 in size and appears across 3 adjacent reels – it only appears when 3 adjacent reels are chosen. When it shows up fully on the reels, you will access the Free Spins feature – here, you will receive 10 free spins.

During the feature, the scatter symbol will retrigger the feature to give you an extra 10 free spins – you can do this multiple times until the maximum win is reached! Basically, you will get infinite free spins if the scatter appears. More importantly, the 3 central reels are locked together to show the same symbols – Mega Symbols only appear to give you bigger wins.

Sound complicated? Imperial Opera is rather simple I think – the key is to trigger the Free Spins feature and get a few retriggers to win plenty of free spins. The fact that the Showcase feature applies on each free spin can lead to huge wins of up to 2,500 times your stake (on every free spin). Be careful though as this is a highly volatile offering. If you like high variance games, Play ‘N Go has plenty with Planet Fortune and Viking Runecraft recommended.
