Rules
---------
The game is played between 2 players with each player
is given with 7 or 10 cards.
The objective of the game is to form Runs(or Sequence)
and(or) sets. A declaration should not have any dead woods
A set is 3 or 4 cards of the same value(or rank) but
with the different suite.
A run(or sequence) consists of 3 or cards of the same
suite and are in consecutive order
The match is played by each player until one player
reaches the fixed maximum score
On the first turn of the round, the non-dealing player
has first option of taking the up-card on the discard pile or
passing.
If the non-dealing player takes the up-card, he or she
must then discard a different card to the discard pile.
The player acting second can take the top card from
the pile of his or her choice.
However, if the non-dealing player passes the upcard,
the dealer is given the opportunity to take the upcard or pass
If the dealer also passes, the non-dealing player must
draw from the stock pile, then the next turn and after, players
can draw from the pile of his or her choice.
On each subsequent turn, a player must draw either the
(face-up) top card of the discard pile, or the (face-down) top
card from the stock pile, and discard one card from his or her
hand onto the discard pile
Players alternate taking turns until one player ends
the round by knocking, going Gin, or until only two cards remain
in the stock pile, in which case the round ends in a draw and no
points are awarded.
Player with 10 or fewer points of deadwood may knock.
The game ends when a player reaches the predefined
