Teknikker at mestre på Svær
- Hidden Pairs technique — Cascading neighbour eliminations silently thin boxes until two digits cling to two cells — after every cascade settles, recount each box rather than trusting your memory of it.
- X-Wing-teknik — Hard anti-consecutive grids open nearly empty; chains of ±1 eliminations are designed to leave a digit two-per-row, at which point the X-Wing is the planned next step.
