This is the first lvl from a game called plants vs. zombies. When the game starts hold down the mouse on the plant at the top and drag to the lawn to put it down. They will start shooting peas. Dont place them on the edges of each square or it won't work. don't bother about the brown lanes. Stars will come down. Click it to add 25 to your sun meter; you need to use it to plant plants. Each plant costs 100 sun. Make sure the zombies don't reach the end. The peas will damage the zombies. When the level progress reaches the end and all zombies are dead you win. If a zombie reaches the end of a lane a lawnmower will come and kill all zombies in the lane the first time. After that if a zombie gets to the end of that lane you lose. to use the trowell drag it and hold space when the plant you want to remove is in the middle of the trowell. In online everything is slower but the timers (zombie respawn rate, level progress , star respawn rate and pea respawn rate.)
