Strategy
Start with the easy rows. Spots with only one possible number give you instant confidence. Then hunt for “forced” cells—those that must satisfy both a math equation and the Sudoku rule. Keep an eye on the operators; a plus sign can hide a hidden‑sum, while a minus forces a subtraction chain. When the board tightens, switch to the “back‑track” mindset: place a number, test the outcome, and undo if the math breaks. Progression is measured in speed and accuracy. The faster you clear a level, the higher your score, and the more complex the equations become. Master the rhythm, and the game turns into a high‑score sprint.
