UNO

No. Resolve the draw penalty and skipped turn; another penalty card cannot pass it on. This guide excludes stacking house rules.

Wild Draw Four is legal only if your hand had no card of the active color. A matching number in a different color does not prohibit it. WANGO permits a bluff that the recipient may challenge.

Only the recipient may challenge. If the offender had a matching color, the offender draws four; otherwise the challenger draws six. Accepting means drawing four and skipping. WANGO reveals evidence only to the challenger, not the entire table.

You may draw one voluntarily, then play only that newly drawn card or pass. Forced draws resolve their card effects instead.

Call UNO with one card left. Physical rules allow catching a missed call before the next player begins. WANGO uses two seconds normally and five in slow local practice; friend rooms use normal timing. Follow the displayed timer; fixed seconds are not a physical rule.

Classic 108: 25 in each color plus four Wild and four Wild Draw Four. Numbers score face value; Draw Two, Skip and Reverse score 20; wilds score 50. Extra cards from 112-card decks, UNO Flip and No Mercy are excluded. WANGO does not automatically run a 500-point match.

Skip skips the next player. Reverse changes direction. Draw Two makes the next player draw two and lose their turn. A normal Wild chooses the next color without a draw penalty. In physical two-player play Reverse acts as Skip; WANGO uses four seats and reverses direction.
