Sequence is a board and card game. The board shows all the cards of a 2 standard deck, except for the Jacks, laid in a 10 x 10 pattern. The four corners are free and count for all players equally.

The players compete to create rows, columns or diagnals of 5 connected checkers placed on the cards that the player has laid down. Two-eyed jacks are wild, while one-eyed Jacks allow an opponents checker to be removed. The game ends when someone has reached a specified number of connections.
