Abstract: A method and system implement a wagering event on an underlying wagering event using a processor, memory, video display, player input controls and player value-in-value-out system. The method includes: a player position committing a wager on an underlying wagering event randomly distributing available into areas distributed along paylines; the processor distributing symbols along paylines; the symbols including at least two classes of collectible symbols: a first class of symbol having positive game content effects upon collection of a first predetermined number of the first symbols, or a second class of symbol having an elimination effect on the first class of symbols upon collection of a second predetermined number of the second symbols; and the processor enabling beneficial payout effects when the first predetermined number of the first symbol is reached and at least some collected first symbols eliminated upon collection of the second predetermined number of the second symbols.
