Store description excerpt
Sudoku the way you actually want it — including the giant 16x16 boards almost no other app offers. WHAT MAKES IT DIFFERENT • 16x16 grids. Four times the board, the same pure logic. • Every puzzle is solvable by logic alone. No guessing, ever. Each one is verified against a technique solver before it ships — if a human can't reason it out, it doesn't go in. • Print them. Export to PDF in A4 or US Letter, 1, 2 or 4 puzzles per sheet, with an optional answer key at the back. SIX DIFFICULTIES, HONESTLY LABELLED Easy, Medium, Hard, Expert, Extreme and Master. The tier is the hardest technique the puzzle genuinely requires — not a guess based on how many numbers are missing. MORE THAN ONE WAY TO PLAY • A 158-level journey that ramps from singles to XY-Wing • A new Daily Challenge every day, with streaks • Killer Sudoku, with cages and sums • X-Sudoku, where both diagonals count too • A solver for the puzzle in your newspaper LEARN THE TECHNIQUES — FREE Every lesson is free, with worked diagrams: naked and hidden singles, locked candidates, pairs, triples, X-Wing and XY-Wing. Each one teaches exactly what the next difficulty demands. BUILT FOR REAL PLAYING • Works completely offline. No account, ever. • Pencil marks, undo and redo, auto-check you can switch off • Letters instead of numbers on big grids, so every symbol is one character • Light and dark themes, seven languages SUBSCRIPTIONS Sudoku XL is free to play.
