Face cards (Jacks, Queens, & Kings) and cards like 10s, for example, are adaptable since they can be used in a variety of sets and sequences. Players can improve their odds of creating winning combinations & preserve their sataaoptions for subsequent turns by giving priority to these cards during gameplay. When using Calchar, players should also take the idea of "blocking" into account. To do this, one must purposefully discard cards that might aid opponents in finishing their sets or sequences while keeping cards that will improve their own hand. Discarding heart cards that aren't needed for your own hand, for instance, can stop an opponent from collecting hearts.
