Mini Sudoku on PlayRove

Fill the four-by-four grid so every row, column and outlined two-by-two box contains one, two, three and four exactly once. Given numbers stay fixed. Tap an empty square to cycle through numbers and clear it. Play the daily Mini Sudoku or choose practice for another puzzle.

Use the small-box rule

Each outlined 2 × 2 box must contain 1, 2, 3 and 4 once each. If a box already has 1, 2 and 3, its last empty square must be 4.
