Developed by Pragmatic Play, the online slot game "Black Bull" presents an engaging layout with 5 reels, 4 rows, and 20 distinct pathways to achieve victories. The game captivates players with its emphasis on accumulating money symbols, an aspect that becomes particularly enthralling during the free spins rounds thanks to an innovative progressive feature. Until players reach these rounds, winnings can be accrued through line wins by aligning three to five identical symbols. The game dictates that all symbols must align on adjacent reels, from left to right, initiating from the first reel on the left.
The hierarchy of symbols begins with the card royals, ranging from Jack to Ace. These symbols offer a reward of twice the stake for landing a sequence of five identical ones. Following these, the game introduces a variety of wildlife-themed symbols, including lizards, a mysterious horned creature, eagles, wolves, and the titular black bull, which stands as the game's most prestigious symbol. Securing a five-of-a-kind win with these premium symbols can result in payouts ranging from 4 to 25 times the player's bet, depending on the specific symbol involved.
"Black Bull" also features two pivotal symbols: the wild and the money symbol. The money symbols are particularly notable for their ability to display a random monetary value, which can range from 0.5 to 50 times the total bet. The unique aspect of these symbols is their interaction with wild symbols; every time a wild symbol appears, it collects the values of all money symbols present on the reels. This mechanism not only adds an extra layer of excitement but also allows wilds to fulfill their traditional role of substituting for all standard pay symbols, with the added benefit of being as valuable as the bull symbol when they form winning combinations.
The game's free spins feature is triggered by the accumulation of money symbols. Specifically, landing between 6 to 11 money symbols rewards players with 6 free spins, gathering 12 to 17 symbols results in 8 free spins, and amassing 18 to 20 symbols triggers 10 free spins. The initiation of this feature sees the collective value of all money symbols that activated the round being summed up and set as the baseline for the bonus round's progressive feature. This not only raises the stakes for the upcoming spins but also provides players with a thrilling opportunity to amass significant winnings as they engage with the dynamic and immersive world of "Black Bull."
