DECLARE CARD GAME (MOD) 2.9

The rule of the game is to minimize the points of cards in our hand. If we feel it is minimum among the 4 players, we can declare.
If it is minimum indeed, then we win, and we get 0 game score. If somebody else has game points less than or equal to ours, then we lose and he scores 0 game score and we score double our points as game score.
We throw high point cards and pick up low point cards. We can throw multiple same number cards at a time.
We can pick only one card at a time. We can pick a card from the deck or the open card.
We can declare only after 3 moves. After a game, we are allotted our score. It is max-score if we are not the last, or else it is (second last- our game score) if we are the last. The score gets added up each time. The medium level is locked initially, If your score reaches 2000, medium level is unlocked.
