Card Sequence is a classic strategy card and board game, also known as Wild Jacks or Crazy Jacks. The objective of the game is to form lines of five adjacent counters in any direction, horizontally, vertically, or diagonally, by matching board squares to cards in your hand. This free version of the game allows you to play against a computer AI player only, not against your friends. The computer AI uses sophisticated artificial intelligence algorithms to provide three levels of computer player skill. The game controls have been optimized for ease of play on all sizes of screen.

To win a game, the player must form a specified number of sequences, one, two or three, before the computer opponent. The board consists of 100 squares, consisting of 96 playing card pictures plus four corner squares, which are wild cards. Each player is dealt seven cards at the beginning of the game. The cards a player holds determine which board squares the player may play a counter on. At each turn, the player plays a card from his hand, puts a counter on one of the matching squares on the board, and receives a replacement card.

Please note that the computer AI does not cheat in any way. The computer does not know what cards you are holding, and the cards, including Jacks, are dealt completely randomly. Beginners might find it challenging, as the computer might beat them most of the time if set to the highest difficulty level. The game provides three levels of computer player skill, and the player can choose the level that suits him best.

Card Sequence is the perfect game to play anywhere, as it doesn’t require internet access. Its accurate representation of the real board game with higher resolution images of the cards and board than other versions, and challenging AI-based opponent make it a must-try game. The game also features one-eyed and two-eyed Jacks, which are color-coded for ease of recognition. Playing a "Two-eyed" Jack allows the player to place a counter on any unoccupied square on the board, while playing a "One-eyed" Jack allows the player to remove any one of the other player's counters, provided it does not already form part of a sequence. Note that when playing a one-eyed Jack, the player does not also play one of his own counters.

If you enjoy the Card Sequence game, an ad-free version is also available. You can search for “Card Sequence Deluxe” in the Google Play Store to get an uninterrupted experience of the game. Remember, if you’re new to Sequence, don’t leave a bad review or rating just because the computer AI beats you most of the time. Playing the game multiple times can help improve your skills, and the luck will average out over time.
