A Hearts trick-taking game built with purely functional language - Haskell to understand and improve functional programming through design patterns skills.
The game of Hearts is a trick-taking game where the goal to score as few points as possible. All cards in the Hearts are worth one point, and the Queen of Spade is worth 13. The goal is to implement a simple AI to beat other players of this game.
At the core of the game of Hearts are the point cards: all cards in Hearts and the Queen of Spade. The goal of the game is to score as few points as possible. An alternative exists though: if a player manages to take all point cards, she gets 0 points and every other player gets 26 points (the maximum).
At the end of each round, when players have played all the cards in their hands, we tally the points in every trick taken by each player. That is, we sum the point cards they won.
The game goes on until at least one player has scored more than 100 points and there is exactly one player with the lowest score. The player with the lowest score is the winner.
Counting points in Hearts is done as follows:
- Point cards: Each Hearts is worth 1 point, the Queen of Spades is worth 13 points.
- Hand: At the end of each hand (players have played all their cards), each player receives the amount of points in the tricks they won.
- Game: The game stops when a player has reached 100 points and exactly one other has the lowest score; the latter is the winner.
