UNO Show 'Em No Mercy is a brutal, intensified version of classic UNO with more cards, harsher penalties (draw 10+ cards!), and new rules like stacking penalties (Draw +2s, +4s, etc.), hand swapping on 0s and 7s, and a "Mercy Rule" where players with 25+ cards are out, making the goal to be the last player standing or first to empty their hand. It's designed for chaos, featuring tough Wild Cards and cards like "Discard All" and "Skip Everyone" for maximum disruption.
