What is 4×4 Medium Mini Sudoku?
4×4 Medium Mini Sudoku keeps the tiny grid but removes some givens, creating a faster puzzle with a bit more thinking.
You fill a 4×4 grid with digits 1–4 so each row, column, and 2×2 box has no repeats.
Medium 4×4 puzzles typically contain 6–9 given numbers (givens), compared to 8–12 in easy grids. The fewer starting givens mean you'll need to track candidates more actively.
