Ooh Aah Dracula by Barcrest may sound like a football chant, but it is actually a terrifying free slots game with a tonne of visuals and music relating to Bram Stoker's original novel's blood-sucking count. You may play this game in your computer browser or on mobile and tablet devices without registering or depositing real money.

In addition to making use of a fairly standard wild symbol, this game also has a scatter symbol to watch out for, which is represented by a ruby-red heart with a stake rammed right through its centre. Get at least three of these scatters at the same time and you will trigger the free spins bonus, which gives you 15 free spins. Unlike some other slots games, you cannot earn more free spins while this bonus is active, but you do get to keep any wilds that appear on the reels for the duration of the round.

Another nice feature of this game is the Best Strategy Indicator, which is represented by a skeletal arm protruding from a gravestone. This will give you a hint about whether or not the time is right to collect according to an array of statistics, saving you the trouble of having to work this out for yourself.
