Security
Portable games do not need to be installed for them to function (all data is stored within a single .exe file) so there is no chance of being infected with viruses / spyware or any other kinds of malware.
This is a common problem amongst free games.

Freedom
Portable games are ready to run applications and can be transfered from computer to computer via an USB drive or any other kind of mobile data storage system.
Portable games can also be used on computers that you may not have Administrator level permission on like a work / school / college computer. |
