A 52-card standard deck is usually used in 777 Rummy, a variation of the classic rummy card game played by two to six players. The main goal is to be the first player to make sets and runs & remove every card from their hand.rummy vip hack Runs are sequences of three or more successive cards of the same suit, whereas sets are made up of three or four cards of the same rank.

As an illustration, a run might include 2, 3, 4, & 5, but a valid set could be 3, 3, and 1 or 5, 1, and 1. Each player receives seven cards at the start of the game.
