After my first game, Chroma Circuit, I wanted to create simpler matching game that would appeal to wider audience. I came up with Gridshock, which is a bit of a mix between Tetris and Collapse.
Instructions:
Match three or more lights, in any direction, to clear them from the grid. If the grid fills up, the game is over! Simply click each row on the grid to activate new lights. Control the tide as the timer fills up and new columns are activated automatically. Get big cascading combos for the maximum possible score.
Alternative Keyboard Controls:
The UP and DOWN arrow keys change rows. The SPACEBAR activates a light.
