Abstract
Payout methods in a mechanical, an electro-mechanical and/or computer-based slot machine-like games-of-chance enable a series of awards based upon: appearance of predetermined symbol combinations in the symbol matrix; issuance of awards for the predetermined combination of symbols; removal of the winning symbol combinations from the symbol matrix; replacement of removed symbols with other symbols; issuance of awards for predetermined combination of symbols in the symbol matrix; and recurring cycles of award, removal and replacement until no winning symbol combinations appear in the symbol matrix.
