Aside from developing fundamental tactics like melding, defense, & bluffing, there are a number of sophisticated strategies that can help you succeed in 777 Rummy. One sophisticated tactic is to keep an eygame 567e on each player's point total during the game to determine who is the biggest threat and modify your plan of action accordingly. This could entail choosing which players to take aim at with defensive play or bluffing to get an advantage and upset their plans. Being aware of how leaving the game too soon or too late may affect both your opponent's and your own point totals is another sophisticated tactic.
