You can outsmart your opponents by knowing how likely it is that a given card will be drawn or that a particular sequence will form. For instance, you can modify your stratcolor rummyegy if you are aware that there aren't many cards in the deck that will allow you to finish a sequence. Keeping track of the cards that you and your opponents have discarded is one method of calculating probabilities. You will be better able to determine which cards are still in play and how likely it is that you will draw them as a result.
