Quiz15 is a quiz game for 2-5 players on one iPhone, iPod Touch or iPad, but…
You can play with more then 5 players if you play as teams and one player keeps his finger on the iPhone/iPod Touch/iPad and the others team members grab his/her arm. When one in the team are sure about the correct answer he/she will lift the arm and release the button. It´s recommended to use an iPad with these sort of gaming. It can be very tight doing this with an iPhone or iPod Touch.
