Hypothesis Sudoku

Sudoku on PC

Hypothesis Sudoku is a PC Sudoku puzzle game built around solving classic 9×9 grids through logical deduction. You enter digits and candidates, then use the game’s reasoning tools to work through the board. When deductions stop, you can make an assumption and follow its consequences instead of guessing at an answer.

Two solving modes

Verification Mode checks entries immediately, which suits relaxed solving and practice. Hypothesis Mode keeps answers hidden while you test assumptions. Assumptions appear in purple; deductions made from them appear in green, including candidate marks. You can build multiple branches, return to an earlier checkpoint, and backtrack when a branch leads to a contradiction.
