A Descent into Madness Feature is triggered when the Bonus Bet is activated and 3 or more scattered logos appear left to right. The highest paying out symbol is the joker touting his joker card at 2000 coins for 5, 100 for 4, 50 for 3, and 4 for 2. The Commissioner comes in value next, then the bat mobile and bat cycle, the bat signal, bat wings, and bat plane.
The Descent into Madness Feature is only available when the Bonus Bet is activated and when it is activated an additional Batman symbol is added to reels 2, 3 and 4 at random.
The special Bonus Bet feature works as such: activate the Max line and make a total bet of 60 credits instead of 50 to unlock an extra bonus feature then click the Bonus Bet button and the spin button to start.
The Batman Re-Spins Feature is awarded when Commissioner Gordon appears on reel 1 and the bat signal appears on reel 5 or bat signal on reel 1 and Commissioner Gordon on reel 5. After paying winning combinations, reels 2, 3 or 4 will expand. The expanded reel is held and all other reels are re-spun 3x. All respin are doubled and the Batman re-spins feature can continue to be retriggered. Re-spins are played at the lines and bet of the triggering game.
