Avalon X uses a six-column, seven-row cluster grid rather than fixed win lines. Winning clusters increase a global multiplier and create wilds that can merge or split as clusters connect. Five mystery boxes activate their reveal feature. Three bonus symbols start free drops; a super bonus supplies Holy Strike on every drop. X-iter offers separately priced entry modes, so these purchased modes should be distinguished from a normally triggered bonus.
To compare related slots formats, read the rules of Ankh of Anubis Awakening and Coin Volcano.
The library also explains the difference between lines, ways and clusters to help put these mechanics in context.
