Guess the hidden answer in 6 tries. In Simple mode each guess is just any 5-digit number - no operators, no arithmetic. In Math mode each guess must be a real, mathematically correct 8-character equation.

After each guess, the tiles change color to show how close you were.

Green means the digit is correct and in the right spot. Yellow means it belongs in the answer but in a different spot. Gray means it is not in the answer at all.

Finishing a round unlocks a brand-new randomly generated code right away - and you can turn off Unlimited mode in Settings anytime for a single puzzle per day instead.
