Blockudoku

What is Blockudoku?

Blockudoku is an addictive puzzle game developed by Easybrain that fuses the mechanics of classic block puzzles like Tetris with the grid-clearing logic of Sudoku. Players are given three block shapes at a time and must place them on a 9x9 grid, aiming to complete rows, columns, or 3x3 squares to clear them and earn points. The game ends when there is no more room to place the available blocks.

How to Play Blockudoku

The objective is simple: keep the board clear for as long as possible while racking up points. Each turn, you receive three randomly generated block shapes that must be dragged onto the grid. You can place them in any order, but you must place all three before receiving new shapes.

Clearing the Board

To remove blocks from the grid, you need to fill a complete horizontal row, a vertical column, or a 3x3 square (similar to Sudoku regions). Clearing multiple zones in a single move triggers combos, which significantly multiply your score.

Scoring System

Points are awarded for placing blocks and clearing zones. Combos and streaks are key to high scores. A streak occurs when you clear at least one zone on consecutive turns, while a combo happens when you clear multiple zones in a single placement.

Top Strategies and Tips

• Plan ahead: Always look at all three available shapes before placing the first one to avoid getting stuck.
• Keep the board sparse: Avoid filling up the center of the grid too quickly. Build outward from the edges.
• Save space for large blocks: Reserve open areas for awkward shapes like the L-piece or the 3x3 square.
• Chase combos: Setting up moves that clear two or three zones at once dramatically boosts your score.
• Maintain streaks: Try to clear at least one zone every turn to keep your streak multiplier active.
• Use the 3x3 zones: Beginners often forget that completing a 3x3 square clears it. Use this to your advantage.
