The most addictive game ever made. Do not start playing unless you're prepared to play constantly. This is a 'capture-the-flag' augmented reality game created by Niantics Labs that poses two different 'factions', the Enlightened and the Resistance, against one another to battle for portals that are GPS synced with public landmarks. Enlightened players are green and referred to as 'frogs'. Resistance players are blue and are called 'smurfs'. Besides being the most addictive game ever made, it's also a great way to meet other people who are also addicted to the game. The only positive lure about the game is that it will teach you about your surrounding areas and educate you about the history of where you live.
