Sudoku Pro

One Game. Two Ways to Play. Four Fixed Difficulties — Choose Freely.

Most Sudoku games let you pick a difficulty on the same grid. This game is different. Here, the grid size is the difficulty — but you're never locked into one. Jump into any of the four challenges anytime you like.

Way 1 – Without 3×3 Boxes (Rows & Columns Only)

Three grid sizes. No boxes. Pure row and column logic.

6×6 – Easy

Numbers 1–6. Only rows and columns matter. No extra constraints. Perfect for beginners or a quick mental warm‑up.

7×7 – Medium

Numbers 1–7. Still no boxes. The larger grid adds a natural step up in difficulty without being overwhelming.

8×8 – Hard

Numbers 1–8. No boxes. This is where pure Latin square logic gets serious. You must track candidates across rows and columns carefully — there are no 3×3 boxes to help you eliminate numbers.

Why play without boxes? Because it's rare. Most Sudoku games never offer 7×7 or 8×8 without boxes. This mode forces you to think differently. You cannot rely on box‑based shortcuts. Every deduction comes from scanning rows and columns only. It keeps your brain flexible.

Way 2 – With 3×3 Boxes (Classic 9×9) – Expert

Grid: 9×9, numbers 1–9.

Difficulty: Fixed at Expert.

Rules: Each row, each column, and each 3×3 box must contain 1–9 exactly once. This is the classic Sudoku that millions love — set at a true Expert level. You will need advanced techniques like X‑Wing, XY‑Wing, and forcing chains. Clues are minimal. Every move counts. It's the ultimate test.

What Makes This Game Different from Others

No other game pairs box‑free 6/7/8 with classic 9×9 in one package.

Difficulty is tied to grid size — but choice is unlimited.

There are four fixed challenges: Easy (6×6), Medium (7×7), Hard (8×8), and Expert (9×9). Simply select the grid size you want to play — the difficulty comes built‑in. You can switch between any of them at any time. No locks, no forced progression.

Two fundamentally different rule sets in one game. Switch between “no boxes” and “with boxes” anytime.

Clean, distraction‑free — just the grid and your logic.

For all ages — anyone can start with 6×6 Easy and grow into 9×9 Expert at their own pace.
