The programs are normally sold as commercial products, typically older stuff but an occasional gem. Basically the idea is that if you like one of them you will be so enthralled that you'll buy other programs from whichever company made them.
The snag is that you have to download and install them the day they are offered or they won't work.
For example, the game today is an update of an arcade game called Quix, Xonix, etc. which I used to love - it's still a lot of fun, there's about seven or eight hours left to download and install it.
