This one’s essentially a digital take on that old party game where you hold a piece of paper to your forehead with something scrawled on it and have to guess what it says from your friends’ clues. The difference with Heads Up is that everything’s played at speed – and it only requires a single device.

The way it works is you select a category and then hold the phone to your forehead so everyone else can see the screen. Get the answer right and you flip the phone down to get a new card. (You can also flip it up to pass.) 

An added twist is using your phone’s camera to record everyone else as you play, providing ample ammunition to embarrass relatives when they offer the most inane clues in history.
