Like many have been asking i have been looking for a bigger screen mode and found a way to take away the pesky ad's bar at the right hand side of everyones game screen, i must stress it's NOT permanent BUT it works and you simply do it each time you load the game up!. 6 simple steps as follows

1: right click on the brown bit just below the game

2: click on inspect element ( a box will come up from the bottom of the screen with a load of code in it ).

3: click the up arrow in the first box a couple of times to scroll up through the code until you find this line < div id="rightcol" role="complementary" >

4: right click on this line of code and you should see the ad box highlight in blue and also a box should pop up with various options, you want to choose DELETE!

5: look over to the right hand side of the screen and click the X to get rid of the element box and you should now have removed the ads box at the right hand side of your game

6: you should now have a fuller screen to play with.

I hope that helps everyone.

I make use of an Adblock rule to automate this:
apps.facebook.com##DIV[id="rightCol"]

If you use Maxthon browser there is an option to popout any flash game/video into it's own window which can then be maximized or resized.

why go through the rigmarole of installing add-on's and stuff when such a simple thing takes less than 30 seconds to do?
