Callbreak Offline Card Game is a four-player strategic trick-based game that is played with a standard deck of 52 playing cards. The game consists of five rounds, where each player bids/calls and competes against three computer players with effective artificial intelligence. The game starts with a single card of any suit (club, diamond, heart, spade), and other players follow the same suit unless they run out of that particular suit. In the absence of an identical suit, the player can throw a card of another suit, and the current round is won by the highest card. Spade cards are used to conquer other cards when no more cards of the same suit are available, for instance, 2 of spade can conquer any higher cards of other suits. If all the players run out of both identical led suit and Spades card, then the led card wins regardless of any suit.
