Gaming systems/processes employing display elements activated by direction-indicating symbols from adjacent display elements. A slot game event provides a display grid having deactivated grid positions and at least one activated grid position. A direction-indicating symbol is randomly presented in the activated grid position, indicating the direction of a deactivated grid position, and the deactivated grid position is activated in response. Distinguishing non-selected grid positions from selected grid positions may involve visually de-emphasizing the non-selected grid positions, such as by dimming or obscuring, or highlighting the selected grid positions. An activated grid position may be deactivated if a stop symbol is randomly presented in the grid position. Game play may be repeated until all activated grid positions are deactivated grid positions and/or de-emphasized grid positions. A currently deactivated and/or de-emphasized grid position may be re-activated in response to the direction-indicating symbol being presented in an adjacent grid position.
