Game Features
Marked Symbol
Sometimes, a random symbol will be selected as the Marked symbol.
Any time a Marked symbol lands, if there are enough of them to pay: the Marked symbols are expanded to cover their entire reel and pay anywhere on a line without the need to be in sequence from left to right in an extra win evaluation.
Any Book symbol that lands together with Marked symbols upgrades the Marked symbols one step, potentially creating new Marked symbols and new expansions.
If the Marked symbol is upgraded past the highest symbol, the lowest symbol that has not yet been converted will be converted into the highest symbol.
