Sudoku: Unlimited Expansion

Sudoku: Unlimited Expansion is a puzzle game built around Sudoku boards that keep growing as you win.

Start with familiar Sudoku rules: fill every empty tile so each row, column, and bold box contains every number exactly once. Then keep going as the board expands into larger layouts and overlapping Samurai-style puzzles.

Choose between Expanding Samurai Sudoku and Sudoku Classic. Samurai mode adds more connected 9x9 boards as you clear levels. Sudoku Classic grows into larger square boards with bigger number sets, keeping the challenge fresh without changing the core logic.

Features:

- Expanding Sudoku boards that regenerate every level

- Samurai-style overlapping puzzles

- Classic square Sudoku mode with larger board sizes

- Numeric symbols beyond 9

- Notes/candidate marking

- Mouse, keyboard, controller, and Steam Deck support

- Camera pan and zoom for large boards

- Difficulty settings from approachable to very sparse

- Optional lives and assist settings

Built for players who enjoy logic puzzles, clean rules, and the satisfaction of watching a small board turn into something much bigger.
