Sudoku: Pieces - Block Jigsaw

Forget tiny pencil marks. Drag numbered jigsaw blocks onto a 9×9 Sudoku grid. Fit every shape, keep 1–9 unique in every row, column, and box. Play offline anytime.

Forget scribbling tiny pencil notes in empty cells—this time, the numbers are already built into the puzzle pieces.

Sudoku: Pieces blends the tactile satisfaction of a block jigsaw puzzle with classic 9×9 Sudoku logic. Instead of typing digits one by one, you drag multi-cell numbered blocks onto the board. Your goal is twofold: every piece must physically fit the grid, and every row, column, and 3×3 box must contain the digits 1 to 9 without repeats.

A block that fits a gap perfectly might still clash with a number down the row. Spot the clues, swap matching shapes, and watch the whole board click into place.

WHY IT FEELS DIFFERENT • Spatial Jigsaw Meets Number Logic: Combine shape-fitting intuition with Sudoku deduction. Placing a single block locks multiple digits at once. • Any Valid Solution Wins: You never have to guess a predetermined layout. If all blocks fit and Sudoku rules are met, you win. • Clean, Effortless Controls: Tap any digit to highlight matching numbers across the board and tray. Reposition placed blocks anytime, or check the reference solution when you get stuck.

FIVE DIFFICULTY LEVELS • Easy & Normal: Generous fixed clues and compact blocks for a relaxing brain warm-up. • Hard & Expert: Sparse clues and larger, trickier shapes that demand deeper deduction. • Hell Mode: Zero starting clues. An empty 81-cell board where only block shapes and pure logic guide you.
