INTRODUCTION to Tapped Four

About Tap 4, from BoardGameGeek:

Get ready for an exciting and strategic card game - Tapped Four! To play, the first player puts down a card, preferably their highest point card. Players take turns laying down cards equal to or lower in value than those on the top of the "Stack" (the play area in the center). You can play cards from your hand or those on the table. When a player completes a set of 4 or more identical cards or plays a "TAP IN" card, they shout "TAPPED" (and for extra fun, give the table a tap), move the "Stack" out of play, and continue their turn. Watch out for special "Trick cards" like the "TAP IN" card, which acts as a wild card to grab the "Stack." The "TAPPED OUT" card gets passed to a player, causing them to lose their next turn. The goal? Be the first to eliminate all your cards to win the round. The player with the lowest score after a series of rounds becomes the ultimate "TAPPED FOUR WINNER."
