Before social media turned my children into zombies, I liked playing games with them so we can laugh and be competitive. There are some great 2-player-1-phone games out there, but they are predominantly reaction based game. Who can tap the fastest? I wanted something that would challenger our brains and pit our wits against each other. Who could think faster, THEN tap fastest. Rival Brains is a 2 player game on one phone where it asks questions like riddles or movie quotes and whoever can tap fastest wins. Similar to a kahoot, but lightning fast and no server needed. Play it at the restaurant while waiting for your dinner. On the couch during commercial breaks. On public transportation where there is no service. It is local on your phone and easy to use.
