The aim of this game is to cross the finish line first by clicking on the 'go' buttons that appear in the game. However pop-up windows will appear within the game covering up part of the screen. By clicking on the X button on the top of these pop-ups will make them close. Each level you will get more pop-ups and they will also get bigger in size until they fill the game screen.
If you type the phrase "nopopups" the pop ups on the screen will disappear. Only works one a game.
