Aces

Each receives 13 cards.
The game consists of a draw of bribes. The right of the first turn for the participant sitting to the left of the dealer. Then the participant who has received the previous bribe starts the rally. In the game there is a certain order of trumps: hearts, diamonds, crosses, vinuses. The trump card changes during the game only after the last trump card has come out. The next batch begins again with worms.
And one more rule. Partner surrender after his first move in the game does not accept: he puts his cards on the table and disposes of his friend.

Additionally scored aces - each for 1 point.
The game consists of a number of games and lasts until the moment when some pair of players first dial 10 points.
