Key Points About Trump Cards:

1. Designation:

The trump suit is usually determined at the start of the game, either by a bidding process, a random draw, or a specific rule.

In some games, a specific card (e.g., the Joker) may always act as the trump card.

2. Usage:

Players can use a trump card to win a trick if they cannot follow the suit that was led in the trick.

Trump cards are particularly valuable in games where winning tricks is the goal.

3. Examples in Games:

In Bridge, the trump suit is decided by the bidding process.

In Hearts, there is no trump suit, but certain cards have special rules.

In Euchre, the trump suit changes with every round.

In Spades, the Spades suit is always the trump suit.

4. Strategic Importance:

Knowing when to play or hold onto your trump cards is often critical to winning a game. Players might use them to secure critical tricks or save them for a decisive play.

The term "trump card" is also used metaphorically in everyday language to describe a secret advantage or decisive factor that guarantees success.
