I'm looking for help finding out the name of a card game. It's know to us as the "Bob and Sandy" game based on the couple that introduced it, but nobody - including Bob and Sandy - knows the real name of the game.

The basics are as follows:

• Each player gets six cards, arranged face down in a grid three wide and two high
• Two cards are turned over, one top and one bottom, not on top of each other.
• The goal is to score as low as possible. Cards are valued with their number, with ace=1. Kings are zero, jokers are -2. If you match both cards in the column, the column scores zero. If you four matching cards in two columns, it scores -20.

There are some other rules about exchanging cards.

Anybody know what it's called?
