Economic Party Games is a board game played with phones. In most turns you commit to an action on your phone, then place it face down on the table. When everyone is ready, reveal your choices. You will need some paper or a spreadsheet(!) to keep score.

The original version was a single device, pass and play version and is available for iPhone and iPad:
