Abstract
The present invention relates to an electronic gaming machine and method for a game of play for use in a gaming establishment, or on a general purpose computing device for offering games with multiple outcomes. The outcome of game play is displayed as a symbol matrix on a display device. The symbol matrix has a predetermined number of rows and columns, wherein symbols are randomly arranged in the symbol matrix. In response to detecting a trigger event, a range for matrix expansion is randomly defined or selected from a number of possible ranges for matrix expansion. An expanded symbol matrix is created and displayed, wherein the range for matrix expansion is indicated in the expanded symbol matrix. Then an active symbol area is determined for at least one consecutive game play, which usually is larger than the symbol matrix and which may be changed dynamically for each game play the feature is triggered.
