It was named after the Prussian General Field Marshal, Gebhard Leberecht von Blücher, who is supposed to have liked playing it.
In the centre is a betting board, on which the numbers 1 to 13 are marked and on which the players place their stakes.
After all players have laid their bets, the banker draws 13 cards, one after another, from the talon, counting aloud and turning them face up.
Each time the value of the draw card matches the announced number, he takes all the placed bets from the corresponding field on the board as winnings for the bank.
When all 13 cards have been faced, if no cards matched the announced number, the banker doubles all the stakes and the players may now claim their winnings, stick or re-bet.
