Block Sudoku

About Block Sudoku

Block Sudoku fuses the block puzzle format with classic Sudoku logic into a single, color-driven challenge. Colorful number blocks must be placed on a grid so that no duplicate numbers appear in any continuous row or column segment, with obstacles on the grid dividing those segments. Each color-coded block is restricted to its matching colored area, adding a placement constraint on top of the number rules. Special hint challenges layer in extra requirements, making every puzzle a multi-rule brain workout.

How to Play Block Sudoku

The goal is to fill the entire grid while satisfying all Sudoku rules, color-zone restrictions, and hint requirements simultaneously.

Placement Rules

• No duplicate numbers may appear in any continuous row or column segment; obstacles on the grid act as dividers that break segments.
• Each color has specific placement zones, so a block can only land in the area that matches its color.

Complete Hints

• Yellow circled cells must each contain a different number from the others.
• Number hints mark the exact digit that must be placed in that cell.

Win Condition

Fill every cell on the grid while following all number rules, color-zone restrictions, and hint requirements.

Controls

• Drag and Drop: Drag blocks from the bottom panel onto the grid.
• Snap to Place: Blocks automatically snap to their correct positions when close enough.
