Number puzzles

Number puzzles look like math but play like strategy. Fill a grid so every row, column and box holds each number once, or merge matching tiles and keep space open for the next combo. You do not need to be fast at sums: the skill is spotting patterns, ruling out what cannot fit and keeping the board under control.
