I know how to play hearts as a game.
There's a program called 'mshearts' that works under winos2. It uses a few files, but can be freely downloaded from Win16 patch sites. You can play against three computer players, or three over the network.
You play the game by playing 'tricks', that is, whoever has the 'lead', puts a card (of any suit), and other players follow with cards of the same suit. If you have no card of that suit, then you can play any other card. So if I lead something like five-diamonds, you have to put a diamond-card if you have one, but any other card if you don't.
The highest card of the same suit as the lead card wins that trick and becomes the lead.
The object of the game is to have the lowest score when someone gets 100 points. A point comes from every heart card in tricks that you win (whatever the lead), or 13 points from the Q-spades. If you get all of the points, then everyone elses' score goes up by 26, while yours stays as it is.
It's in my OS/2 themed "Windoze"
