Overview

For this assignment, you will be writing a program to play the card game Intensity.

The Rules of Intensity

Intensity is an unusual card game which is thought to have originated in post-WWII buffalo hunting camps in Australia's Northern territory. The name intensity is thought to derive from numbers in groups of ten being important.

Cards

It is played with a deck of 40 cards.

The cards are numbered 10 to 49.

No two cards have the same number.

11 cards have special significance. They are the cards numbered 30 to 39, usually called the calves, and the card numbered 47, usually called the buffalo.

Game Play

Intensity is played by four players sitting around a circular table. These players are numbered clockwise: 0, 1, 2 and 3. The deck is divided randomly among the 4 players. So each player starts with a hand of 10 cards.

Stage 1: Discarding

In the first stage of play, each player selects three cards from their hand to be passed to the player on their left (clockwise). They, of course, then receive three cards from the player on their right. So player 0 passes to player 1, player 1 to player 2, player 2 to player 3 and player 3 to player 0.

The four players simultaneously select the three cards to be passed on. Each player must pass on 3 cards, before receiving the three cards from the player on their right. Hence, you must select the three cards you will pass to the player on your left before you know which three cards you have been given by the player on your right.

Stage 2: Playing Cards

The second stage of play consists of a series of 10 rounds. The goal of the game is to avoid penalty points during these ten rounds.

A round begins with a designated player selecting a card from their hand and playing it. Then proceeding clockwise, the other players, in turn, each select a card from their hand and play it.

Hence for the first round, each player will have ten cards in their hand to select from, for the second round they will have nine cards in their hand and so on. For the tenth and last round, each player will have only one card and hence, no choice in the card they play.

Playing a Card

The first digit of the first card played in a round is important. The subsequent players must play a card of the same first digit as the first card if possible.

For example, if the first card played in a round is the 17, the other 3 players must play a card with a first digit of '1' if they have one in their hand.

If one of the players does not have a card with a first digit of '1' in their hand they may play a card of another first digit. The following players are still required to play a card with a first digit of '1' card if they have one.

Winning a Round

A round is won by the person who plays the card of the same first digit as the first card in the round with the largest number. For example, if the first card in a round is the 24, the card with the largest number with first digit '2' will win the round. If no other card with the first digit '2' played the 24 wins.

Player 0 plays the first card of the first round. Subsequently the winner of each round plays the first card of the next round.

If, for example, player 2 won the last round, then player 2 would play the first card of the next round and then players 3, 0 and 1 would play in that order.

Buffalo and Calves

One restriction to the above rules is that a player is not allowed to play a calf (a card in the range 30..39) as the first card in a round unless a calf has been played in any of the previous rounds or they have only calves in their hand. This restriction does not apply to playing a calf as the second, third or fourth card in a round.

In other words, if no cards in the range 30..39 have been previously played, a card in the range 30..39 can not be played as the first card of a round unless the player has no choice.

There is no restriction on when the buffalo can be played as the first card.

Penalty Points

The aim of Intensity is to avoid penalty points. A player scores penalty points if certain cards occur in rounds they have won. Each calf is worth one penalty point and the buffalo (47) is worth 7 penalty points.

Hence, generally players try to avoid winning rounds which contain calves and they particularly try to avoid winning rounds which contain the buffalo.

If a round doesn't contain a calf or the buffalo it doesn't affect the score.

When all 10 rounds are played the penalty points are calculated for each player. The winner of the game is the player with the fewest penalty points.

If a player attempts to play an illegal card they receive five penalty points. The referee will instead select a legal card from their hand at random. This same applies to discards.

To fully understand these rules, it might be worth watching this tutor-made video which runs through an example game of intensity.
