Players are initially confronted with a variable-reel matrix, with sliding columns atop each reel. These columns inch up at least one spot for every Horus symbol that lands. These can max out to create a 6x9 structure offering a staggering 531,441 ways to win.
If any column expands to its full height, a Bonus Wheel will be launched which can award free spins, a respins mode, a small or large prize wheel, or sticky stacked wilds, as players unlock the full potential of the reels.
The Bonus Wheel is one of two ways to unlock the free spins, with the mode also launched if three or more Scatter symbols land on a single spin.
During the feature, all reels are reset to three symbols high, with a Bonus Wheel being awarded if the column fully expands. The two prize wheels and sticky stacked wilds remain present on the main wheel, while a direct cash prize can also be awarded.
Players can also increase their chances of unlocking a Bonus Wheel with the Boost, or progress directly to the free spins phase via the Buy Bonus.
