In Block Blast, avoiding small empty gaps is key to lasting longer and scoring higher. Here are some effective strategies:

1. Plan Ahead:

Before placing a piece, look at all three available blocks and visualize how they could fit together on the board. Don’t rush to fill spaces that might limit your options later.

2. Prioritize Corners and Edges:

Fill corners and edges carefully, since these areas are where small gaps often appear. Try to place larger or L-shaped pieces first to build out a clean base.

3. Keep Spaces Open for Common Shapes:

Leave room for frequent block shapes like the 3‑in‑a‑row or 2×2 squares. Avoid creating narrow single‑cell gaps, since only a few pieces can fill them.

4. Maintain a Balanced Board:

Spread out your placements so one area doesn’t become too cluttered. A balanced board provides more fitting options for future blocks.

5. Undo and Recheck (if available):

If the game allows an undo function, use it when you realize a placement leaves behind small gaps you can’t fill.

Careful planning and spacing make a big difference—aim to think two or three moves ahead.
