Quick Play PC Version

Although in the Program Files, in Plants vs. Zombies folder, inside "images" folder, there is A Quick Play right left of the Tree (The tree that you saw in the Main Menu), But it is unknown how to access Quick Play.

I sticked the Quick Play image from the folder to the game

If your pvz GOTY game has black rectangles in the left and right of the game is in full screen, enable the 3D acceleration and put your mouse on the top very left corner of the left black rectangle. Then move your mouse down and you will see that your mouse will suddenly turn into a hand. When it turns into a hand, click. THAT IS A BUTTON FROM THE QUICK PLAY SCREEN!!! But when you click it, nothing will happen. That's because the button says BACK. I still don't know how to acces quick play but I posted this as a clue.
