Rock Grid Rumble
The objective of the game is to have more rocks of your own color than your opponent when the match ends.
Some locations on the grid cause something special to happen. Hover over these markers with the mouse to see what effect each symbol represents. The match ends when one of the top two grid markers is occupied.
Use YOUR MOUSE to aim and fire the cannon on your turn only.

After every level you'll have the option to upgrade your tank and buy more weapons or ammo. As the levels go up the enemies will increase in number and will be more powerful. So be careful and avoid getting hit by the enemies or you'll lose health. Use the special weapons cautiously as they are limited in supply.
