## Description

OpSudoku is a fresh twist on classic Sudoku that adds arithmetic to every puzzle.<br><br>It is the 9×9 Sudoku you know - fill every row, column, and 3×3 box with 1–9 — but the grid is also split into &quot;cages&quot;. Each cage shows a target number and an operator (+, −, ×, ÷), and the numbers inside it must satisfy that math while still following all Sudoku rules. One board, two kinds of logic.<br><br>▶ HOW TO PLAY<br>• Fill each row, column, and 3×3 box with the digits 1–9.<br>• Bold borders mark a cage with a small clue like &quot;14+&quot; or &quot;8×&quot;.<br>• The numbers in a cage must match its operator and target.<br>• For subtraction and division the order does not matter (4− means the difference is 4).<br><br>▶ FEATURES<br>• Four difficulty levels: Easy, Medium, Hard, and Expert.<br>• A new Daily Challenge every day.<br>• Every puzzle is guaranteed to have a unique solution.<br>• Memo mode for jotting down candidate numbers.<br>• Smart hints when you get stuck.<br>• Mistake highlighting you can turn on or off.<br>• Clean, modern, distraction-free design.<br>• Play fully offline — no internet required.<br>• Track your stats and daily streak.<br><br>▶ FOR EVERY PLAYER<br>Whether you love number puzzles, brain training, or just a relaxing logic game to unwind with, OpSudoku gives your brain a satisfying daily workout.<br><br>Free to play.
