Wordle falls short of your expectations as a challenger? Then, take a look at its most recent fan-made copy, Nerdle, which is attracting attention for its surprisingly addicting structure. This obviously includes mathematics!
Nerdle is a daily math game created by Reddit user TheMann0707 that differs somewhat from the seed game by substituting numbers and equations for letters and words.
As described in his tweet, Mann broadens the scope of the viral word-guessing game by including a mathematical counterpart that tests your mathematics skills. The main aspects of Nerdle are identical to those of Wordle; you have six chances to solve a daily task, it's totally web-based, and it's available for free; and there is just one challenge every day. You even receive color-coded hints in a conventional manner.
The dissimilarity solely manifests itself in the "composition" of the problem, as the original Nerdle game consists of an 86 grid pattern; i.e., you have six opportunities to deduce an 8-column hidden equation.
