Buy Sudoku: Unlimited Expansion PC key

Sudoku: Unlimited Expansion is a puzzle game where Sudoku boards grow as you clear levels. Fill each empty tile so every row, column and bold box contains each number exactly once. The game has two modes: Expanding Samurai Sudoku and Sudoku Classic.

Expanding boards

In Samurai mode, clearing levels adds more connected 9x9 boards to the overlapping puzzle. In Classic mode, the square boards grow larger and use bigger sets of numbers, including symbols beyond 9. The boards regenerate with every level.

Puzzle options

You can mark notes or candidate numbers, pan and zoom the camera on large boards, and choose a difficulty ranging from approachable to very sparse. Optional lives and assist settings let you adjust the challenge.
