The Batman logo is the wild symbol, it can substitute for all of the other symbols, except for the scatter symbol, to help and form winning combinations.
The scatter symbol simply says ‘Bonus!’ on it.
If you land four matching symbols on the first two reels then the Batgirl Locked Respins begin. You will receive five free respins with the symbols on the first two reels locked in place. The feature can also be triggered by wild symbols and co-op symbols.
The Batman Team-Up Free Games begin if the ‘Bonus!’ scatter symbol lands on reels three, four and five simultaneously. You then play a picking game in which you need to reveal superheroes to fill up their respective meters. Filling the Batman meter first wins you 25 free spins, filling the Batgirl meter wins 17 free spins and filling the Robin meter wins 12 free spins. During the free spins, the first two reels are merged to form one reel that contains giant 2x2 symbols.
The progressive jackpot game can begin at any point while playing and once it does, you are sure to win one of the four jackpots on offer. The game consists of a grid of twenty jackpot icons and you need to pick them one at a time to reveal what colour they are.
