Gogole translate of game description (saga quote):
The basic principle of the dwarf gwent was something resembling a horse auction in the market - so the intensity and the intensity of the voice of the bidders. Then a pair of notifying the highest "price" tried to get as many tricks, so the second pair in every way interfere. The game proceeded loudly and violently, and lay next to each player big stick. Clad with sticks fairly rare, but often waved.

"Contract bridge is a trick-taking card game where on each of several deals the opposing sides first compete in a bidding auction for the right to establish the contract for that deal, the side winning the auction being known as the declaring side. The contract is an exchange of the right to establish which suit, if any, is trumps for an undertaking to win (at least) the number of tricks specified by the highest bid. After the contract has been established, the play of the cards proceeds as in most trick-taking card games until all thirteen tricks have been played; at any time during the play, one side may claim a stated number of the remaining tricks and concede the balance, if any."
