Indian rummy is described as an easy game to earn cash without a large initial investment. It can be played with 2-6 players at a table online or offline. Players are eliminated from the game if their score reaches over 80 points, while the player with the lowest score at the end is the winner. Rummy players can strategize to identify other players' discarded cards and win money by collecting sets and runs. Online rummy sites aim to provide a safe, user-friendly environment for players to enjoy the game.
