As you can imagine, the game is inspired by a dark theme, it's a bit spooky and almost haunted but I do like the color-scheme and it gives me Halloween vibes. Aside from that, the game offers something more unusual- you can choose whether to play it on 3 rows, 4 rows or 5 rows. Of course, that comes with additional cost, while playing with 3 rows comes with a minimum of 10 cent stake.
When it comes to the base game, I don't find it very exciting. If you play with 5 rows, you can possibly get more winning combinations due to having more lines open. Also, you can lock certain reels for additional cost and respin other reels, which can help to land the bonus quicker. But it can become quite cosgly, which is why I prefer not using this "lock reel" option. Also I usually skip to just buy the bonus, which again is possible in 3 different levels, depending on how many rows you want to have active. I usually go with the most volatile option of 5 rows active. Then you get your typical book bonus, where you get 10 free spins and one symbol is your special expanding symbol. However, what makes it stand out is the fact that if you're not happy with your special symbol, you can switch it once- of course there's no guarantee that the next special symbol will be a better one. Then, whenever the symbol lands, it will expand, which is why it's better to play on all 5 rows for bigger win potential.
Having said that, in my experience it's very difficult to get good wins from the bonus round, it definitely is a very high volatility bonus that pays all or nothing. For the most part, even if my special symbol is a low paying symbol, I've never had a full screen of any symbol. But of course I've seen numerous other players getting full screen of top symbols, so it's definitely possible.
Overall, it's an average game with spooky design and high volatility. But somehow I rarely find myself playing this game, as good base game hits are rare and good bonus hits are even more rare. Certainly not in my top list from Nolimit City.
