How the game works
Clusters of at least four matching symbols can pay. Removed winning symbols charge the portal as replacements fall into place. Special wilds can substitute for regular symbols, while the Rich Wilde multiplier wild has a different substitution role.
The feature to understand
Different charge thresholds add wilds or activate portal effects that remove more symbols. A fully charged portal opens the Other World round, where a sequence of effects resolves between cascades. Further grid conditions can release a large Cthulhu wild.
What to look for on mobile
The portal meter and pending effects need to remain visible beside the grid. Follow the order in which a cascade ends and the next effect starts; these are separate steps in the feature.
A useful comparison
Compare with Book of Dead to see how one character appears in different game systems. Reactoonz is a useful second comparison for a charge meter that produces wild-based effects.
