96.1 per cent


Low value symbols come in the form of playing card royals, with Jack through to Ace. If the right number of winning combinations land on a single spin, these symbols can offer between x0.1 and x2.5 the player’s bet. 

Six monsters depict the high value symbols, with Swamp Man, Dead Beard, Princess Cleo, Max Wolf, Adam Frankenstein and Vamptress. These symbols can offer between x0.2 and x10 the player’s preferred wager. 

VS scatters can also drop into play, triggering the VERSUS free spins feature when six or more appear on the same spin. Each scatter will represent one free spins in the bonus game mode when at least six appear at once. 

Finally, wild crown symbols are available, substituting for all symbols other than the VS scatter. 


Throughout the game, and due to the Gigablox mechanic, symbols can appear in larger sizes of 2×2, 3×3, 4×4, 5×5 or 6×6 to increase the win potential as these symbols act as four, nine, 16, 25 or 36 symbols respectively.

When activating the free spins game mode, the game will spin through the six high value monster characters to select two to be enhanced for the duration of the bonus game mode. 

One of these symbols will be chosen as the champion, and the other will be the challenger, each with their own respective meters beside the reels. 

Landing these chosen symbols on the board during the free spins will cause them to climb up their respective meters, awarding prizes when a certain number of symbols have been collected. 

The champion meter will award enhancements such as x2 multipliers for the respective symbol, x5 multipliers, champion symbols turns wild, three extra spins, wild gains x2 multiplier, another extra three spins, wild gains x5 multiplier and, finally, a payout equal to the number of champion symbols collected times by the player’s bet, in that order. 

Meanwhile, the challenger symbol can award x2 multipliers, two extra spins, x5 multipliers, another two extra spins, challenger symbol turns wild, another extra two spins, wild challenger gains a x2 multiplier, a payout equal to the number of symbols collected times by the player’s stake and then multiplied by two, in that order. 


Mark McGinley, Chief Gaming Officer at Yggdrasil, said: “Horror-themed slots have a huge fan-following and Nightmares VS GigaBlox is a great addition to our YG Masters portfolio.
