Teknik untuk Dikuasai pada Mudah
- Nota dalam Sudoku — Before placing anything, note where 1 and 9 can legally sit in each row and column given its clue — sandwich solving is crust bookkeeping, and notes are the ledger.
- Last Possible Number technique — A clue of 0 glues 1 and 9 together and a clue of 35 pins them to the ends — either way, whole rows of candidates vanish and several cells drop to one digit.
- Last Remaining Cell technique — Once a row's 1 is placed, the column clues immediately restrict where that column's 9 can sit — chase each crust digit to its last legal cell.

Outside clues again, but read as building visibility instead of sums — the same edge-of-grid deduction style.
