Staxx (1979)

Staxx is part of Ashburn Industries' "The Quickles" series of card games. Staxx uses a modified standard deck of cards, with two letters on each card and 6 wilds (effectively the jokers and kings). Staxx combines a standard Rummy game with a word game; players score the most for runs and sets that form words, but can meld just words or sets/runs.
