A free, independent Mini Sudoku site — the 6×6 puzzle from LinkedIn, plus 8×8 and 10×10 boards, built to load fast and play well on a phone.
Mini Sudoku is the same logic as classic 9×9 Sudoku in a smaller grid: every row, column, and region holds each digit exactly once. The 6×6 board — the one people share from LinkedIn — uses the digits 1–6 in 3×2 regions and solves in a few focused minutes. PlayMiniSudoku is a free, independent practice site with no account, no app, and no ads on gameplay.
We offer 900 free puzzles — 300 each across three grid sizes: 6×6 (digits 1–6, 3×2 regions), 8×8 (digits 1–8, 2×4 regions), and 10×10 (digits 1–10, 2×5 regions), in easy, medium, and hard. Every puzzle has a single solution reachable by logic alone. Play a new daily Mini Sudoku, generate unlimited boards, or browse the full library by size or difficulty.
