You can play games from previous days by adding a date to the end of the web page that you visit. For example, for the 31 January 2022 game, you can go to nerdlegame.com/20220131 If you enter an invalid date (a future date or a date before that version of the game was launched) you’ll end up at today’s game. The game will default to classic or mini depending on which you played last. Or if you prefer, you can choose using a url such as classic or mini
