Nerdle is the math equivalent of Wordle, challenging you to guess a hidden arithmetic equation in six tries. Instead of letters, you work with digits and operators to form valid mathematical expressions like 12+34=46. After each guess, the game provides color-coded feedback showing which characters are correct and placed, which appear somewhere in the equation but in the wrong position, and which are not used at all. Every guess must be a mathematically valid equation, forcing you to think about both number theory and positional logic simultaneously. This dual challenge makes Nerdle uniquely satisfying for players who enjoy both math and deductive puzzles. Daily mode provides a shared puzzle for competitive comparison, while practice mode offers unlimited equations.
