This expert-level Sudoku 4x4 puzzle is crafted for advanced solvers who are comfortable with complex logic and minimal clues. Unlike easier levels, expert puzzles often require multi-step deductions, pattern recognition, and a strong grasp of solving techniques. It's ideal for players who enjoy deep thinking within a compact puzzle format.
Fill in every empty cell so that each row, column, and 2x2 region contains the numbers 1 through 4, with no repetition. The solution must be reached through logic alone—no guessing or trial-and-error.
