daily math puzzles
guess the hidden equation – a new puzzle every day
Nerdle is a family of daily math puzzle games. In each one, a hidden calculation is waiting to be found. Enter a valid equation, and colour-coded tiles tell you how close you are: green means right character, right place; purple means the character is in the answer but in the wrong spot; grey means it’s not in the answer at all.
Every version follows the same core mechanic, but the size of the equation – and therefore the difficulty – varies. There’s something for everyone, from a quick 30-second solve to a serious brain workout.
