This slot machine transfers you to the streets of Gotham City where Batman is once again trying to rid the streets of super villains like the Joker. As well as Batman, the Joker is also featured on the Dark Knight slot and can actually play the good guy by awarding you some winning bonuses. Whilst you are playing this slot, the Joker or Batman, can randomly appear to award you a bonus which you can hopefully turn into a win.
Batman and the Joker obviously appear on the reels as symbols but other symbols include the Batman signal, the Joker logo and other recognizable things from the Dark Knight movies. Of these symbols, the Batman symbol is always a wild but the Joker symbol can also sometimes be as well. When the Joker feels like being meddlesome, he can also be rewarding to you as he will blow up a regular symbol on the reels and replace it with one of himself and when he does that, it is then that the Joker symbol becomes a wild as well as the Batman symbol.
The Joker is also benevolent when either he or Batman randomly appears to award you an additional bonus. They do not appear together but whichever one does appear, they will reward you with either some free spins or a multiplier. The joker symbol is hopefully very busy as it is also the scatter symbol which means that although it can’t be replaced by the Batman wild symbol, it can trigger the bonus round when you get one of them on each of the 3rd, 4th and 5th reels.
The bonus round on this slot machine, once it is triggered, awards 15 free spins and even though the spins may be free, it doesn’t mean that Batman or the Joker cannot still appear to award you an extra bonus and if that bonus happens to be more free spins, then they will simply be added to the ones you are already playing.
On this slot machine it is also possible to be awarded a random progressive jackpot.
