Block Sudoku blends block puzzles with Sudoku. Blocks of different shapes are offered three at a time, and you drag them onto a 9×9 grid. Complete a full row, column or 3×3 box and it clears, freeing space for more blocks. It is endless, strategic and very more-ish. It is aimed at players aged 8+ and up, and a typical round takes around 8 minutes. If you already enjoy brain-training, Puzzle and logic games, you will feel at home here within seconds.
The goal is straightforward. The on-screen instructions walk you through it, and you can start playing with a single click. Controls are intuitive: use your mouse or keyboard on a computer, or tap and swipe on a phone or tablet. Because everything runs locally in your browser, Block Sudoku reacts instantly and never needs a page reload.
Playing short, regular sessions supports memory, focus and mental agility.
