Key points

  • Gin rummy uses a deadwood-and-knock system; going gin earns a 20-point bonus plus opponent deadwood.14
  • Rummy 500 uses cumulative scoring over several hands; players may take more than the top discard.35
  • The names are used inconsistently; some rule sets add jokers worth 20 points in rummy 500, while gin rummy uses no jokers.56
