Sudoku Puzzle Challenge

What the number puzzle collection covers

Sudoku Puzzle Challenge is a puzzle game built around Sudoku, with five related number puzzle types added alongside the classic grid. The developer lists over 32,000 puzzles across the six types, so it is aimed at people who want a large supply of Sudoku-style puzzles rather than a handful of sample grids.

The collection suits players who already enjoy Sudoku and want more variety within the same kind of logic puzzle. Each type is a separate game mode with its own puzzles.

Classic Sudoku and its basic rule

The standard Sudoku mode asks you to place the digits 1 to 9 so that every row, every column and every 3x3 box contains each digit once. This is the base rule the rest of the collection builds on.

The listing presents classic Sudoku as the starting point, with the other five types offered for players who want a change from the standard grid.

Killer Sudoku, Sudoku-X and Kakuro variants

Beyond classic Sudoku, the app includes Killer Sudoku, Sudoku-X and Kakuro. The listing names these as separate puzzle types but does not describe their rules in detail, so the rules themselves are not covered here.

Each variant has its own puzzles and is counted within the same 32,000-plus total, so switching between types gives a different puzzle without leaving the app.

Mini grids and difficulty settings

Mini Sudoku and Mini Sudoku-X are smaller-format versions of the Sudoku types. The listing includes them alongside the full-size puzzles without giving their grid dimensions.

Every puzzle type comes in Easy, Medium and Hard versions, so the same type can be played at different levels of difficulty.

Playing on phones and tablets

The developer describes the interface as designed for mobile and tablet use, with the puzzle grids laid out for both screen sizes. The listing does not describe other controls, settings or input options.
