Digit Challenge

Digit Challenge is equation gap-filling, not digit recall. Fill two to four blanks using digits 1–9, with each digit available only once, so the expression equals the displayed result.

How to Play

01

Select a blank, then choose a digit from 1–9. A used digit becomes unavailable.

02

Fill every blank and submit when the equation equals the target.

03

More than one assignment may be correct; every mathematically valid unique-digit answer is accepted.

04

Correct answers raise the level; incorrect answers lower it. Clear a blank whenever you want to try another route.
