About this game
You know sudoku. Now play it backwards.
In Sudoku Swap, the grid starts completely filled — but some numbers are in the wrong place. Tap two tiles to swap them until every row, column, and box contains each number exactly once. Simple to learn, surprisingly deep to master.
ENDLESS, FAIR PUZZLES
Every board is generated on your device and verified to have exactly one solution. Five difficulties, from a friendly 4×4 Beginner to a brutal 9×9 Expert.
HINTS THAT DON'T SPOIL
Limited, unlimited, auto-apply — or Non-spoiler mode, with escalating clues that guide you without giving the answer away.
DAILY PUZZLES
A fresh challenge every day, the same board for every player worldwide. Build your streak on the monthly calendar.
MAKE IT YOURS
Dark and light mode, three grid styles, backdrops, visual solving aids, undo/redo, optional timer.
COMPETE WITH YOURSELF
Par-time scoring, per-difficulty statistics, score boards, and 18 achievements to unlock.
Fully offline. No account needed. Ad-supported, with a one-time purchase to remove ads forever.
