Pillz (2008)

From the publisher's website:

Build the special pill!

With each card you place, you try to complete as many pills as possible. Each pill must have to colors in order to score points. You can place one or two cards in each turn, but only one card will score you points. And of course each pill has to fit the others, so no dead ends are allowed.

For 2 Grown-ups, 15 to 30 minutes playing time.
