Hi, I just began this, so during the install tutorial i read:5. Open Angry Birds in Chrome by going to http://chrome.angrybirds.com -a. Click on SD on the bottom left of the game window -b. Click "PLAY" and then click on "Poached Eggs" on the bottom left -c. You will now see the "Level Selection" window But where do i find the game window ?
