Lansquenet (derived from the German Landsknecht ('servant of the land or country'), applied to a mercenary soldier) is a card game. Lansquenet also refers to 15th and 16th century German foot soldiers; the lansquenet drum is a type of field drum used by these soldiers.
Game play 
The dealer or banker stakes a certain sum, and this must be met by the nearest to the dealer first, and so on. When the stake is met, the dealer turns up two cards, one to the right, - the latter for himself, the former for the table or the players. He then keeps on turning up the cards until either of the cards is matched, which constitutes the winning, - as, for instance, suppose the five of diamonds is his card, then should the five of any other suit turn up, he wins. If he loses, then the next player on the left becomes banker and proceeds in the same way.
When the dealer's card turns up, he may take the stake and pass the bank; or he may allow the stake to remain, whereat of course it becomes doubled if met. He can continue thus as long as the cards turn up in his favour - having the option at any moment of giving up the bank and retiring for that time. If he does that, the player to whom he passes the bank has the option of continuing it at the same amount at which it was left. The pool may be made up by contributions of all the players in certain proportions. The terms used respecting the standing of the stake are, 'I'll see' (à moi le tout) and Je tiens. When jumelle (twins), or the turning up of similar cards on both sides, occurs, then the dealer takes half the stake.
There is a very easy means by which card sharpers manage a cheat to perfection. They prepare beforehand a series of a dozen cards arranged as follows:
- 1st Queen 6th Nine
- 2nd Queen 7th Nine
- 3rd Ten 8th Ace
- 4th Seven 9th Eight
- 5th Ten 10th Ace
Series thus arranged are placed in side pockets outside the waistcoat, just under the left breast. When the sharper becomes banker he leans negligently over the table, and in this position his fingers are as close as possible to the prepared cards, termed portees. At the proper moment he seizes the cards and places them on the pack. The trick is rendered very easy by the fact that the card sharper has his coat buttoned at the top, so that the lower part of it lies open and permits the introduction of the hand, which is completely masked.
Some sharpers are skilful enough to take up some of the matches already dealt, which they place in their costieres, or side-pockets above described, in readiness for their next operation; others keep them skillfully hidden in their hand, to lay them, at the convenient moment, upon the pack of cards. By this means, the pack is not augmented.
