1. Snake

If you, like me, grew up in the late nineties and early noughties, youll no doubt remember Snake, a relatively obscure arcade game from the 1970s that was featured on a range of Nokia mobile phones. Today, iPhones, Blackberries and their ilk have immense levels of processing power and are able to offer high quality games to their users, but back in the day, the inclusion of a basic game such as snake on a handset was something to marvel at. It became a hugely popular timewaster as a result. Googles decision to hide a version of the game within YouTube, therefore, is a nostalgic yet highly amusing touch. Capable of being played on most videos that utilise the 2010 version of the sites player (shown below), all it takes to turn a video into the game is the pressing of the left or right arrow key for a few seconds, followed by an input of the up arrow key.
