Endless boards at four difficulties that mean what they say, an academy
that teaches 22 solving techniques, and crisp sheets to print. And when
the puzzle is on paper — newspaper, magazine, book — point your camera
at it and it's in your phone in half a second.
Every puzzle is generated on your phone and graded by the logic it takes
to solve — not by counting clues.

Four difficulties that mean what they say
Easy to Extreme, each level is defined by the techniques the board
actually requires. An Extreme needs Extreme moves — it isn't an
Easy with fewer givens.
Unlimited boards — never the same puzzle twice
Pencil notes, auto-check, and mistake tracking
Hints at three levels that teach the technique, not just the answer
Compete
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. Invite friends to a leaderboard,
or race a bot when you want a live opponent.
A single shared challenge, refreshed daily, with streaks and a calendar
Friend leaderboards — invite with a link, no follower counts
Bot races against a solver matched to your rating

Tutorials
22 techniques, from full house to jellyfish
Every technique gets an interactive walkthrough on a live board —
then a practice puzzle generated so that only that technique cracks
it. Learn the move, then make it yourself.
Step through each move at your own pace, back and forward
Practice boards that can't be solved without the technique
The same ladder the difficulty grades and hints are built on
Generate as many boards as you like and export a crisp PDF — one,
two, four, or six to a page, answer key optional. No printer on
Wi-Fi? Email the file to yourself and print from any computer.
Any difficulty, graded the same honest way
One to six boards a page, with or without solutions
The puzzle in front of you — printed, half-solved, shot at an angle —
lands in the app in about half a second. No shutter button, no typing
eighty-one digits by hand.

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
