Strategy

Start with the obvious: scan each row, column, and square for numbers that appear only once. Flag those spots and lock them in. Next, adopt a pencil‑mark technique—write candidate numbers in a cell’s corner. When a candidate disappears from a line, the remaining numbers become clearer. Progression comes from tackling harder boards; each level adds fewer givens, forcing deeper deduction. Keep an eye on symmetry; many puzzles hide patterns that, once spotted, unlock whole sections. For a lasting challenge, switch to the “hard” mode and let the puzzle push your limits. The more you play, the sharper your intuition becomes, turning every new board into a fresh test of logic.
