Weekend Sudoku 21 Strategy

Start with the obvious. Fill every single‑digit that only fits one spot in a row or column. Then scan 3×3 blocks for hidden pairs. Use the “candidate” technique: jot possible numbers in a cell, then eliminate as other numbers lock in. Progression feels natural—easy grids warm you up, hard grids push your limits. Keep a steady rhythm, and you’ll notice patterns emerging. The more you play, the faster you spot the hidden combos. That’s the sweet spot that keeps the puzzle addictively fresh.
