UNO Dos
One number can be two cards — Uno's standalone sequel where math clears your hand.
The Story
Rule Twists vs. Classic UNO
Everything below is an official printed rule unless flagged otherwise.
Two face-up piles
Unlike UNO's single discard pile, UNO Dos deals out two face-up piles in the center of the table. On your turn you may play on either or both piles.
Single or double-number matching
You can play a single card that exactly matches the number showing on a pile, or play two cards from your hand whose values add up to that pile's number (a "double number match") — letting you shed two cards in a single play.
Calling "Dos"
UNO's "UNO" call becomes "Dos": when you're down to two cards in hand, you must call it out, or risk a 2-card penalty if another player catches you first.
Point-based multi-round scoring
Number cards score their face value and Wild/action cards score 20 points when tallied against the round's loser(s); the first player to reach 200 points wins the match.

Exact special-card distribution
CommunityPublic rules summaries agree on the core double-pile, double-number-match mechanic and the 20-point action-card scoring, but differ on the precise count and naming of every action card variant in the 112-card deck. Treat the special-card list here as representative rather than a verified full manifest, pending direct confirmation against a physical Mattel instruction sheet.
