Reading a printed page — live scan
The scan moment

From the page to your phone in half a second

Point, and every cell is read at once — no shutter button, no typing eighty-one digits by hand.

Scanning a printed board — the app reads 30 of 81 clues at 88% confidence and flags cells to check

Reads print and your handwriting

Puzzlesight tells the printed givens apart from digits you've filled in yourself, in pen or pencil, so importing a half-finished board keeps your progress instead of wiping it.

  • Corrects the angle, even shot from the side
  • Shows its confidence and flags anything unsure
  • Tap a misread cell to fix it in a second

Stuck on a paper puzzle? It'll tell you where you went wrong

Scan the board you're solving in pen and Puzzlesight checks your work against the one true solution — pointing to the exact square that broke the puzzle, without handing you the rest of the answer.

  • Finds the first wrong move, not just "something's off"
  • Keep solving on paper — nothing is filled in for you
  • Or import it and finish in the app instead
The daily challenge screen — one shared board per difficulty, the same for everyone that day, with a streak calendar and reminders
Daily

One puzzle. The whole world. Every day.

Everyone gets the same daily board, so your time means something — and a mistake cap keeps it honest. Come back each day to keep your streak alive and watch your best times fall across every difficulty.

  • A single shared challenge, refreshed daily
  • A mistake cap raises the stakes — no infinite retries
  • Streaks and a calendar that reward showing up
More than a solver

A full Sudoku app around the camera

Friend leaderboards

Invite friends with a link and see who reads and solves the daily board fastest. No follower counts, no noise — just your people.

Hints that teach

Three levels of help, your call: a gentle nudge toward the right area, the name of the technique to use — a naked single, a locked pair — or the exact next cell. It teaches the method instead of just dropping the answer in.

Endless, fresh play

Generate new boards across four difficulties — Easy to Extreme — with pencil notes, auto-check, and mistake tracking. Never the same puzzle twice.

Print & solve on paper

No printer nearby? Export a crisp PDF — one, two, four, or six boards a page, answer key optional — and print it from any computer.
