The board shows every card from two decks (except Jacks) laid out twice each. The four corners are free spaces that count for everyone.
Your turn
Play one card from your hand and place a chip on a matching space on the board.
Draw back up to a full hand from the draw pile.
If a card in your hand is dead (both its spaces are already covered), discard it instead of playing, and draw a replacement.
If the draw pile runs out, the played cards are shuffled into a new draw pile.
Jacks are special
2-eyed jacks (♦ ♣) are wild — place a chip on any open space.
1-eyed jacks (♥ ♠) remove one opponent chip — but not from a completed sequence.
Winning
Line up five chips in a row. A free corner counts for anyone. With two colors in play you need 2 sequences; with three colors, just 1.
A completed sequence is yours for the rest of the game: its chips can't be removed, and a second sequence may share only one chip with it. If one move completes lines that overlap too much to all count, you choose which sequence to keep.
Teams
4 players = two teams (blue & red). 6 players = three teams (blue, red & green). Teammates alternate seats and share a color.
