Pygame - project-owner/Peppy.doc GitHub Wiki
Pygame comes with some versions of Raspbian OS. To make sure that it's available in your OS version start Python interpreter and type the following line at prompt:
import pygame
You shouldn't see any exceptions. If you see import exception that means there is no Pygame and it should be installed by using the following command:
sudo apt-get install python3-pygame
Pygame leverages library libsdl1.2 which has some issues with touchscreens. Therefore the patched version of libsdl1.2 should be loaded and installed (many thanks to Gerhard for making the patch):
wget https://www.dropbox.com/s/0tkdym8ojhcmbu2/libsdl1.2debian_1.2.15+veloci1-1_armhf.deb
sudo dpkg -i libsdl1.2debian_1.2.15+veloci1-1_armhf.deb
sudo apt-get -f install
rm libsdl1.2debian_1.2.15+veloci1-1_armhf.deb
