UNO: Dos

You are shedding your hand onto two centre piles instead of one. Play a card whose number matches a pile, or two cards that add up to it; the first player to empty their hand ends the round, and 200 points takes the game. Matching colour as well as number is a Double Colour Match, which lets you discard a bonus card and forces everyone else to draw. Wild Dos cards count as any 2. Down to two cards, you call Dos, and forgetting costs you a draw, exactly as in the original. This is Mattel's number-first spin on UNO, so the rules land in three minutes, but the small arithmetic makes it feel like a new game rather than a re-skin. Pick it up for a family with school-age children or as a change of pace on a UNO night.
