Who can make Batman stronger? That would be his teammates – Batgirl and Robin. Batman & the Batman Bonanza is an online slot game created by Playtech that comes with retro visuals and simple animations. But, this game has an unusual setup of reels (5 reels, 60 paylines) and reels of different sizes. Once again, the Batman signal is the wild symbol that replaces basic symbols to help players create winning lines. The game also features co-op symbols for extra wins. Different combinations of the main character symbols will activate fun mini-games with Free Spins, respins, extra wilds, multipliers and many other memorable features.
