7 Heart game is played with 4 players and with standard deck of 52 cards. At the start of the game 52 cards are shuffled and distributed to all 4 players in sequence such that each player gets 13 random cards.
The player having 7 Heart card plays first and then the following player and so on in clock-wise fashion. Each Suit can only start with face value of 7. In each turn player plays the matching higher or lower card or seven card, player skips chance if there is no matching card. Player who finishes all cards first wins the game.
The main aim of the game is to get rid of higher value cards and keep the score as low as possible. Ace(A) has the value of 1 and King(K) has value 13.
When the game ends the score is calculated by adding up values of all remaining cards. For example let us say Player 1 has J and Q then his total score = 11(for J) + 12(for Q) = 23
The trick to win the game or keep your score low is to block other players cards by playing only the cards for which you have higher or lower cards.
E.g. If you have these cards: 8 Heart, K Heart, 9 Club, 6 Diamond then you play 8 Heart since you want other players to play other higher Heart Cards so that you can play K Heart, you refrain from playing 6 Diamond and 9 Club unless you do not have any other cards to play.
