Jungle

This is the 5th of the "Bonsai Game" of daVinci, complete games on a single card (board on a side, rules on the other side).
The board is divided in 12 squares, containing snakes (negative points) or apples (positive points). The players alternates in placing two fingers of one hand on two free contiguous squares. For each covered apple, the player scores a point, for each snake, he lose a point.
The first player places on the board the fingers of the left hand, then the second player places the fingers of both hands, then the first places the remaining hand, and then the players alternates removing and re-placing any hand.
The winner is the first that scores 30.
