Soadnation has updated his pack of games called Mini Games Galore.
These games are pretty simple to play and loads of fun. He's added another simple game called Quadroball, originally made for a TI-93 calculator.
In his own words, "You have to move the arrow from one side of the screen and then back to the starting side to get three points. The balls all travel at random speeds and if you get hit, you lose. It's more difficult then it sounds."
You'll need Lua Player to pay these games. Grab it if you don't have it.
