The official name for this game is Universal Monsters Dracula because it’s the fourth NetEnt slot using a classic Universal Studios movie as theme after Frankenstein, Creature from the Black Lagoon and The Invisible Man.
Dracula uses 40 lines and all symbols, except wild, appear stacked during normal play.
At any moment during normal play Dracula can change into a group of bats. These bats fly across the reels and create a block of one and the same random symbol, including wild. After the block is created the reels stop spinning.
Dracula also comes with a free spins feature. Get a fully stacked Dracula symbol on reel 2 (3 symbols high) and a fully stacked girl symbol on reel 4 (3 symbols high) to start 10 free spins. During the free spins feature the Bat Feature happens on every spin. The free spins also have a stacked wild symbol (3 symbols high) on reel 3. When this symbol appears fully stacked you are awarded with 2 more free spins.
Dracula looks amazing and the Bat Feature appears pretty often. It is possible that all symbols turn into one and the same symbol.
