About Numberly
Numberly is Streakly's set of daily number and maths puzzles: hit a target with four sums, crack a four-digit code, fill a mini sudoku, balance the scales, find the mystery number and more. Every puzzle is checked to be fair before it goes live, and everyone gets the same one each day.
You get six attempts, with helpful feedback after each one. Solve it early for up to 12 points, use the helper if you're stuck (it halves your score), and build your streak. No timers, just a calm daily brain teaser. See how scoring works →
