About this game

Ninegrid is Sudoku, the way it should be: no ads interrupting your focus,
no ambiguous puzzles, just clean logic from the first cell to the last.

Fill the 9×9 grid so every row, column, and 3×3 box contains 1 through 9
exactly once. Tap a cell to select it — its row, column, and box highlight
automatically — then tap a number to place it.

Every puzzle has been checked by a real solver to guarantee a single,
logical solution. No guessing, ever.

FEATURES
• 150 hand-verified puzzles across three difficulties
– Gentle (~38 givens), Classic (~30 givens), Sharp (~25 givens)
• Guaranteed unique solution on every board — solvable by logic alone
• Row/column/box highlighting for the selected cell
• Simple number-pad entry, no fiddly typing
• Live conflict detection across rows, columns, and boxes
• Earn up to three stars per puzzle for efficient solving
• Calm graphite-and-jade visuals, easy on the eyes for long sessions
• Gentle ambient soundtrack and tactile feedback — both toggleable
• Fully offline. No ads, no accounts, no tracking. Progress stays on your
device.

The classic, done right.
