Casper’s Mystery Mirror Gameplay

The higher value symbols of Casper’s Mystery Mirror are Casper’s ghostly pals, plus an old fashioned book and some tall candles. In addition to these are the lower value playing card symbols from Ace to 9.

There’s a wild Casper symbol, which appears as stacked and will substitute all symbols within the game but the Casper bonus symbol and the Mystery Mirror.

Bonus Features of the Slot

Casper’s Mystery Mirror only offers one bonus feature, which is quite a surprise for an NYX game, as they are often brimming with features. However, it’s a good one due to the Mystery Mirror element.

You will need to land 3 Casper bonus symbols in view in order to trigger the feature, which consists of 5 free spins. We know you’ll be thinking that 5 free spins don’t sound like a lot, but fear not – the Mystery Mirror feature can make this a lucrative bonus round.

When the free spins begin, the Mystery Mirror symbol becomes active. This picks a random reel symbol and this is then revealed in every single Mystery Mirror in view.

This, of course, should create plenty of winning combinations and hopefully give that bank balance a lovely boost. Furthermore, should you land yet another 3 Casper bonus symbols during the free spins game, the bonus feature will be re-triggered.


Casper’s Mystery Mirror isn’t one of NYX Gaming’s most stand out releases, but it is enjoyable, simple and completely easy to play. The bonus feature is enhanced due to the Mystery Mirror feature which can potentially increase your winnings quite substantially.

We’d recommend sitting back, sticking the autoplay feature on, and relaxing as you watch the reels of Casper spin.
