opposition
A game of skill and deception.
Free · Designed for iPad
In loving memory of Bob Packard. 1937-2019.
Opposition was invented as a board game in the 1970’s by Bob Packard, a high school math teacher from Alaska. Bob was my father. He made game boards out of mahogany in his wood shop, then he’d take my brother & me to school where we’d play against his students. I brought the game to the iPad and iPhone.
Fixed bug with Donate popover that obscured the informative text.
