Blockudoku

Blockudoku is a puzzle game that tasks players with placing blocks on a grid to complete full rows, columns, or 3×3 squares. This combination of block puzzle and sudoku mechanics offers a unique challenge that increases as you progress.

The fun comes from balancing spatial reasoning and logical planning. Players must think ahead to fit varying shapes while making strategic moves to clear as many lines or squares as possible. The difficulty ramps up as space on the board decreases and the block options become trickier.

Blockudoku rewards careful consideration and pattern recognition, making it a great choice for puzzle enthusiasts looking for a fresh challenge beyond traditional block or number games.

How Blockudoku works

Players receive a set of blocks each turn and place them on a 9×9 grid to fill horizontal rows, vertical columns, or 3×3 squares. Completing any of these fully clears them from the board. The goal is to prevent the board from filling up entirely by efficiently clearing spaces and planning placements. The game ends when no more blocks fit on the grid.

Strategy tips

• Focus on completing 3×3 squares as they clear more area.
• Plan placements to avoid isolated spaces that block future moves.
• Keep the board as open as possible by clearing lines frequently.
