All-Seeing Eye
There's no avoiding the gaze of Yog-Sothoth's many eyes but this could be used to your advantage. Randomly on any spin, an Eye Frame can appear on the map to the left of the grid. Should any winning clusters appear on the grid in relation to the Eye Frame on the map, two to four Wild symbols will appear on the grid. This can lead to some unexpected cascading combos.
Portal of Chaos
With every win, the Portal of Chaos charges up by one per symbol. There are four levels you can reach at 8, 16, 30 and 48 charges. Each level provides a different portal effect. The first grants two to four Wilds, the second level can eliminate symbols, the third level can upgrade low-paying symbols into more valuable ones, and the final charge awards a Free Spin complete with all of the previous effects. It's also possible to overcharge the portal for seven additional effects, each requiring +4 winning symbols per effect.
Damned Ritual
The map to the left of the grid may light up with red and green eyes in various positions and you can activate the eyes by landing winning combinations on the marked positions. But should you trigger 12 red eyes you'll want to prepare yourself. This will summon the almighty Yog-Sothoth - grandfather to Cthulhu himself – as a 2x2 mega wild played out in a 3-step sequence. Alongside that, activating three, four, or five green eyes will apply a x2, ×3, or ×4 win multiplier to Yog-Sothoth's Mega Symbol. Additionally, all remaining portal effects will grant four Wilds during the summoning of this terrifying entity.
