About Gridshock
Match three or more lights, in any direction, and don't let the grid fill up! Control the tide as the timer fills up and new columns are activated automatically.
Gridshock Instructions
Match a set of three or more adjacent lights to clear them from the board. A set of matched lights need not appear in a straight line. Earn more points by creating multiple matches at once. Click a row with the mouse to activate a new light. Alternatively, use the up and down arrow keys to navigate the rows and the spacebar to activate a new light.
