The bat symbol is the wild symbol and it can substitute for all the other symbols, except for the scatter symbol, to help and form winning combinations.
The scatter symbol is the word ‘Bonus’ on a pink background.
If you land the bonus symbol on reels one and three simultaneously, the Cat Burglar Bonus begins. You need to pick one of the bonus symbols to win an instant cash prize or to increase the multiplier by 1x for the next free spins round. If the multiplier value is at least 2x then the triggering symbols become special diamond symbols in the base game and they award a cash prize whenever they appear.
If the bonus symbol lands on reels one, three and five simultaneously the Batman vs Catwoman Free Spins begin. You have to pick a Batman symbol to reveal the number of free spins you win and a Catwoman symbol to reveal the multiplier (which is added to the multiplier from the Cat Burglar Bonus). At the end of the free spins, the diamond symbols on the reels are replaced by scatter symbols and the next 24 spins have a 50% chance of triggering more free spins.
The slot has four progressive jackpots up for grabs and the jackpot game can be triggered at any point, regardless of which symbols land on the reels. Best of all, once it starts, you are guaranteed to win one of the four jackpots on offer. The game consists of a grid of twenty icons; you need to click on them to reveal one of four colours. Each colour corresponds to one of the jackpots up for grabs and you win a jackpot by filling up its meter. To win the Mini jackpot you need to find two green icons, the Minor jackpot is won with three blue icons, the Major jackpot is won with four yellow icons and the massive Grand jackpot is won by finding five red icons.
In addition to the progressive jackpots, there is a top fixed payout of 2,500x up for grabs for landing five wilds along a payline. Batman can payout up to 400x, Catwoman can payout up to 200x, Robin can payout up to 150x, the Batcopter and Batboat can both payout up to 100x, the whip and gold cats can both payout up to 75x, and the belt and Batarang can both payout up to 50x.
