Discard Jail after you skip one turn. (1st Edition: Jail was not discarded until a heart ♥ or diamond ♦ was drawn.)
When performing a draw! for jail, the flipped-over card must be hearts ♥ to get you out of jail. (1st Edition: The flipped-over card could be hearts ♥ or diamonds ♦.)
Sid Ketchum has 4 life points. (1st Edition: Sid Ketchum had 3 life points.)


There were also a few changes in cards' names:
