## Description

GridSolve is a clean, ad-free classic Sudoku puzzle game. Every single puzzle<br>is generated fresh on your device and verified to have exactly one valid<br>solution before you ever see it — no guessing games, no dead ends, just<br>real logic-driven Sudoku. No account, no ads, no internet connection<br>required.<br><br>HOW TO PLAY<br>- Fill the 9x9 grid so every row, column and 3x3 box contains the digits 1<br>  through 9 exactly once.<br>- Tap a cell to select it, then tap a number on the pad to fill it in.<br>- The selected cell&#39;s row, column and box are highlighted automatically, so<br>  you always see what&#39;s already ruled out.<br><br>FOUR REAL DIFFICULTIES<br>- Easy, Medium, Hard and Expert puzzles, tuned by the number of starting<br>  clues — from a gentle ~40+ givens down to a sparse 24-26 for Expert.<br>- Every puzzle at every difficulty is generated with a randomized<br>  backtracking algorithm and checked with a solver to guarantee a unique<br>  solution, regardless of how sparse it looks.<br><br>FEATURES BUILT FOR REAL SOLVERS<br>- Notes / pencil-marks mode — jot small candidate numbers into any cell<br>  without committing to an answer, exactly like solving on paper.<br>- Optional conflict highlighting — instantly see cells that clash with the<br>  same number in their row, column or box.<br>- Optional same-number highlighting — shade every cell that already holds<br>  the number you&#39;ve selected.<br>- Hints — reveal the correct value for your selected cell (or the next<br>  empty one) when you&#39;re stuck, with hints-used tracked per puzzle.<br>- Undo — step backward through your move history, including note toggles<br>  and erases, not just final answers.<br>- A live timer for every puzzle, with your best time saved per difficulty<br>  so you can chase a personal record.<br><br>STATS THAT STAY ON YOUR DEVICE<br>A dedicated Stats screen tracks puzzles completed and best time for each<br>difficulty, your total puzzles played, and your current daily play streak<br>— all stored locally, never uploaded anywhere.<br><br>FOUR APPEARANCE MODES<br>Choose System, Light, Dark, or a pure Black &amp; White theme for maximum<br>contrast and battery savings on OLED screens.<br><br>PRIVACY BY DESIGN<br>GridSolve works completely offline.
