The word when Canvas Pinball was launched was that it was Microsoft’s attempt at showcasing the HTML5 capabilities of the Internet Explorer browser. However, Canvas Pinball is much more than that. This game brings back the memories of the good old Pinball game that was so popular a few years back. There are the usual two flippers that can be used to smack the ball around and keep it in play. Canvas Pinball is a great entertainer.
