In the game of Sequence, players take turns drawing playing cards from a deck and placing markers on the matching images of the cards printed on the game board, according to BoardGameGeek. Five markers in a row is a sequence. The first player to reach a set number of sequences wins.
The Sequence board is printed to show traditional playing cards in a 10-by-10 grid with each of the 52 playing cards appearing twice, except for jokers. Poker chips or checkers are also included in three different colors. The main aspect of the game play is simple. Each player must try to create a sequence of five connected cards with checkers on them. A sequence can run horizontally, vertically or diagonally across the board.
Drawing a two-eyed jack allows the player to place a checker anywhere on the board, while drawing a one-eyed jack lets the player remove one of an opponent's checkers. A two-player game is won with two sequences, and a three-player game with one sequence, according to HowStuffWorks.
Sequence is a game that is based in both mathematical strategy and luck. While it's impossible for the players to anticipate the next drawn card, they still must choose strategically whether to connect the card to an existing sequence, begin a new sequence or remove an opponent's checker. Additionally, the players of the game are discouraged from pointing out possible advantageous moves to their opponents, meaning that each player must rely on his own wits and spatial awareness to gain the upper hand.
