The game has multiple versions, each with its own distinct rules & subtleties, and it can be played with two or more players. Players are dealt a set number of cards to start playing rummy; depending on the variation, this number is urummy tosually seven or ten. With the top card face-up to begin the discard pile, the remaining cards form a draw pile. After taking turns drawing from the draw or discard pile, each player discards one card from their hand. The other players reveal their hands to determine points based on unmelded cards after one player successfully melds all of their cards. Any player must grasp these fundamental mechanics since they serve as the cornerstone for more complex strategies.
