About this Slot
BlackJack Mayhem is a Joker, Money and Classic-themed slot from Darkbyte with an RTP of 96.5%, medium volatility and a maximum win of 25,000x. The game uses 6 reels, 4 rows and 4,096 ways to win.
The Joker Wild substitutes all paying symbols and reveals a multiplier from a ladder. When multiple jokers land on the same spin, their multiplier values multiply together. A Charged Wild appears when the dealer lands on an existing wild, adding a second multiplier roll ranging from x2 to x1,000.
Cards positioned above the reels hold multiplier values from x2 to x100. Jokers reveal these card values only after a winning spin, with each revealed card value adding to the others before the total multiplies the win. More jokers on a spin expose more cards from the ladder.
Mayhem Dice triggers when dice lands on a winning spin. The dealer throws the dice across six hands ranging from 17 to BLACKJACK, with higher hands carrying stronger multiplier values.
Free spins begin with 3, 4, 5, or 6 21-chips and unlock four tiers: HIT, DOUBLE DOWN, SPLIT and BLACKJACK. Jokers stick in place throughout the entire free spins round, and the board becomes richer as the bonus continues.
Six bonus buy options are available: Double Chance at 2x bet, TRIPLE CHANCE at 3x bet, HIT at 100x bet, MYSTERY SHOE at 128x bet, DOUBLE DOWN at 150x bet and ALL IN at 200x bet.
