Block Blast

Game Guide

Overview

Block Blast is an endless spatial packing puzzle played on an eight-by-eight board. Three different polyomino pieces are offered at a time. Place each piece on empty cells without rotating it or overlapping occupied squares. Completing every cell in a horizontal row or vertical column clears that line immediately. The challenge is not color matching: it is preserving useful open geometry while fitting awkward shapes and setting up simultaneous line clears.

Controls

Use the arrow keys or the four direction buttons to move the landing cursor. Choose cycles through the unused pieces in the current set; Tab performs the same action on a keyboard. Press Space, Enter, or Place to commit the highlighted piece. A green preview means every covered cell is legal, while red means part of the shape is outside the board or overlaps an occupied cell. Reset creates an empty board and a fresh set while retaining the local best score.

Scoring and Progress

Every occupied square adds a small placement score. A completed row or column pays a much larger award, and clearing multiple lines in one placement counts each line. Consecutive scoring placements build a combo multiplier; a placement that clears nothing resets that combo. When none of the remaining offered shapes has a legal position, the board refreshes instead of showing a permanent game-over screen, so practice remains endless and the accumulated best still records efficient packing.

Strategy Tips

Read the whole three-piece set before placing the easiest shape. Long bars need uninterrupted lanes, while L shapes need corners that a single square cannot repair later. Build near the edges first and avoid dividing the center into isolated pockets. A nearly complete row is useful only if the missing cells match a remaining piece. Simultaneous row-and-column clears are powerful, but keeping two broad landing zones is usually safer than forcing one immediate line.

Mobile Play

On a phone, Choose, Place, and every direction control remain at least forty-four pixels high and sit below the board, so fingers do not hide the preview. Move the cursor until the ghost shape turns green, then confirm with a separate tap. Debug mode evaluates real legal placements and keeps choosing available shapes, rather than replaying a fixed animation. render_game_to_text exposes the full board, three piece shapes, selection, cursor, score, combo, and legal-placement counts for runtime checks.
