For example, if an opponent routinely removes particular kinds of cards from the discard pile, it can mean that they are trying to finish particular melds. Players can modify their own tactics by identifying these play for free slotspatterns, either by blocking those melds or by giving priority to other sets & sequences that could help them win. Players can also choose which cards to discard more wisely if they are aware of the patterns of their opponents. A player should refrain from discarding cards from a specific suit or rank if they observe that their opponent has been gathering those cards in order to avoid unintentionally helping them form melds.
