Sudoku Workshop

Sudoku Workshop is sudoku made by someone who actually plays it.

A NEW DAILY PUZZLE, FREE, EVERY DAY
Pick any of five difficulties, from Very Easy to Expert, and watch your solves fill in the calendar.

DIFFICULTY THAT MEANS SOMETHING
Puzzles are rated by the techniques they actually require, solved the way a person solves them, not by counting clues. A Hard puzzle needs a Hard technique.

LEARN THE TECHNIQUES
Eleven lessons, from naked singles through X-Wings, Skyscrapers and chains. Each one walks through a real board, then lets you practice on positions where that technique is the move.

MORE THAN 9x9
Grids from 4x4 up to 25x25, plus X-Sudoku, Hyper and Jigsaw variants.

PLAY THE WAY YOU LIKE
Tap a keypad, pick from a palette, or write digits by hand. Pencil marks stay in a fixed place in every cell, so you never have to re-read a note. Pinch to zoom on any grid.

MAKE IT YOURS
28 color palettes, highlighting you can tune, and optional hints that point to a cell and name the technique without giving away the answer.

TRACK YOUR PROGRESS
Stats, badges, and a calendar of every daily you have solved.
