I had a sixteen-day streak at one point, but I lost it a few days ago, I'm trying to build it back up. (Also, wouldn't this be better recieved in one of the main forums?)
How many days long is your chess.com streak
To maintain a long streak, here is a cheat code. You don't have to play games, you don't have to review your games, all you have to do is go on Chess.com every day, play the Martin bot, lose or win, that's one added day to your streak. You can continue to do this thousands and thousands of times, Chess.com doesn't care unless you at least play a game.
Mine is 31 days
