Why do skat players bid game values instead of naming contracts?

In the card game skat, players bid by announcing the potential game value—the calculated score of their proposed contract—rather than naming the specific contract itself. This system is used because the final value of a game is determined by a combination of factors, including the chosen trump suit (or grand), the number of matadors held, and additional declarations like schneider or schwarz.

By bidding the value, players express the minimum worth of the game they intend to play. This allows for flexibility; for instance, a declarer playing "with the skat" does not need to announce their specific game until after they have incorporated the skat into their hand and made their discards. As long as the game they eventually announce meets or exceeds the value they bid, the requirement is satisfied. This mechanism creates a strategic auction where players compete to become the declarer while ensuring their hand is strong enough to support the value they have committed to achieving.1
