We carry this format of Rummy in which all players at a table play each hand with the same number of chips and the number of deals is also fixed. The player who wins all the chips at the end of each deal is the winner of that deal. At the end of the fixed deals, the player with the highest number of chips is the winner.
No game or any other diversion is an addiction in itself. As players, we need to stay vigilant, behave responsibly, and engage in the game only as a source of recreation. True that there are fantastic rummy tournaments on various rummy portals, and they are great opportunities to test your rummy skills and generate some real money, but restrict it to that. Be wise, and use rummy to your advantage!
