Skip: the first player loses their turn.; Reverse: direction flips, so the dealer plays first.; Draw Two: the first player draws two and is skipped.
Why people argue about this
People often assume that if an Action Card is drawn first in UNO, they can simply play it immediately without skipping anyone, but actually, the turn order is dictated by the official rules: Skip for a "Skip" card and Reverse for a "Reverse," flipping direction accordingly; Draw Two cards are mandatory for any player who draws them, regardless of their position.
