Inside Sudoku
Fit every digit using row, column and box constraints. Three difficulties, every puzzle generated with exactly one solution. Tap a cell, then a number. Find a row or box with few blanks before trying a crowded area. Select a cell, then choose a digit using the game’s number controls.
The game retains its English interface. Its own menus and tutorial describe the current release.
Make your move.

Click or tap inside the player before using keyboard controls. Flexible orientation. Touch support does not guarantee the same performance on every phone.

Session notes.
Pause, reload & saved progress
Pause using the game’s own controls before leaving. SENOVIRA cannot reliably pause or mute an external game. Reload restarts the frame and may discard unsaved progress; Unload removes it. Neither clears the game’s storage. Browser privacy settings may separate embedded and direct saves.
