UNO: Swap Pack Add-On of 16 cards brings new excitement and unpredictability to the classic UNO card game by introducing unique card-swapping mechanics. Cards such as Swap 1 allow players to exchange a random card with another player's hand. Refresh Hand enables players to completely discard their current hand and draw an equal number of new cards from the draw pile, drastically changing their game strategy. The Wild Force Trade lets a player choose two participants, including themselves, to trade their entire hands, followed by selecting the next play color. Wild Pass Hands dramatically reshapes gameplay by having all players pass their hand to the next player in the current order, again allowing the initiating player to choose the continuing play color. This dynamic add-on makes strategy shifts and sudden game changes frequent, maintaining constant player engagement. —description from the rulebook (adapted)
