## What is Wildoku?

Wildoku is every Sudoku in one app. Classic, Killer, Thermo, Jigsaw, Samurai, Arrow, Sandwich, Kropki and 48 more variants, each at five difficulties.

If Classic Sudoku has started to feel the same every day, this is where to go next. In Killer Sudoku you add up cages. In Thermo, digits climb along a thermometer. Samurai is five overlapping grids solved as one puzzle. Boards run from 4x4 to 12x12, and difficulties from Easy to Pro, where a board starts with almost nothing on it.

Each variant has a short lesson that shows you its rule on a real board, so you can start one you have never seen. When a puzzle stops you, a hint names the strategy that solves the cell and opens its page. There are 88 solving strategies to look up, from Naked Single to X-Wing and Swordfish.

Not sure which variant to try next? Journey, on the Play tab, is a road through every variant, one difficulty at a time, starting from Classic. Each stage is a chosen board, the same for every player, and the boards get harder the further along the road you go.

There are no forced ads: no banners, and nothing between puzzles. The only ads are the ones you choose to watch.

Puzzles are made on your device, so you never run out and never get the same board twice. Everything works offline, with no sign-up and no account to create.

The Daily Challenge is a new Sudoku every day, in a different variant each time, with a calendar to keep your streak going. In the Sudoku Maker you build your own puzzle, mix the rules you like and share it with a friend, who plays it in their own app.

Pencil marks tidy themselves up when you place a digit, and you can tap a cell first or a number first. The app keeps statistics for every variant and has achievements to earn. It plays in portrait or landscape, in Dark, Light or High Contrast, with a colour vision setting, in eleven languages.

Five variants are free forever, six more are free each week, and the Daily Challenge is always free. Premium is one payment, with no subscription. It opens every variant, the Pro difficulty and every past Daily Challenge, and it removes the ads.

All 56 variants: Classic Sudoku, Sudoku 4x4, 6x6, 8x8, 10x10 and 12x12, Killer Sudoku, Sandwich Sudoku, X-Sums, Quadruple, Little Unique Killer, Skyscraper, Ascending Sequences, Running Cells, Thermo Sudoku, Slow Thermo, Arrow Sudoku, Between, Lockout, Slingshot, German Whispers, Dutch Whispers, Renban, Modular, Entropic, Parity, Palindrome, Zipper, Nabner, Bishop, Region Sum, Kropki, XV, Consecutive, Greater-Than, Couples, Twisted Consecutive, Even-Odd, Axia, Friendly Cells, Index Lookup, Jigsaw Sudoku, Sudoku X (diagonal Sudoku), Windoku, Disjoint Groups, Anti-Knight, Anti-King, Anti-Bishop, Non-Consecutive, Miracle, Samurai Sudoku, Twin, Gattai-3, Butterfly, Sohei and Kazaguruma.
