In one of the bonus rounds on this slot machine, bats can bring an end to the round and so you must try and avoid them. As the Blood Suckers slot is themed on Vampires, a lot of vampires are featured as symbols on the reels despite one of the other symbols being garlic. A horror type atmosphere is created with eerie sounds that include the wind quietly howling and the occasional scream and hoot but the atmosphere really comes to life when one of the vampire wild symbols appears on the reels. When this vampire wild appears, you are treated to the gruesome sight of it biting the neck of one of its victims. The scatter symbol is a vampire bride and you won’t miss her appearance as it is accompanied by a loud thump.

Obviously, vampires can’t be allowed to run around freely and so when you reach one of the bonus rounds, your job is to stick stakes in the hearts of as many as you can but you must do it before the bats put an end to the round. When the bonus round is triggered, you are transferred to a new screen that has as its setting, a grave yard. In the grave yard there are 12 coffins lying on the ground and nine of these coffins contain vampires and the other 3 contain bats. One by one you select a coffin and if it has a vampire inside it, you are to stick a stake in its heart, destroying it. If however, you select a coffin that contains bats, the bats will fly away but before they do, they will end the round.

The second of the bonus rounds available to be triggered on this slot machine, is a free spin round. Once triggered you will receive 12 free spins with which to try and earn as much as you can but to assist you in earning more, each win that you are able to obtain will pay three times its usual pay-out amount, which certainly will help.
