The product, called Hercules High And Mighty, was developed by Barcrest and has a variety of extra features. Huge pillars stand on either side of the reels and have a chain on them that raises and lowers a bar to increase the number of active paylines, but there will be more later.
As the field expands, the chain rises to bring in all the extra paylines; when the Hercules symbol is fully visible, this also happens in the base game.
