To excel at Block Blast!, consider these strategies:

Plan Ahead: Always look at the three blocks you have available and try to anticipate their best placement, as well as how they might set up future clears. Don't just place the current block in the first available spot.
Keep the Center Open: The middle of the board offers the most flexibility for placing larger and oddly shaped blocks. Filling it up too early can limit your options significantly. Try to build around the edges and keep space in the center.
Aim for Combos: Actively look for opportunities to clear multiple lines simultaneously. This is the fastest way to boost your score.
Manage Grid Space: Every block placement should be purposeful. Avoid leaving small, isolated gaps that are hard to fill with later blocks. A tidy board gives you more options.
Utilize Special Blocks/Power-ups (if available): Some versions of Block Blast! include special blocks (like bomb blocks that clear a larger area) or power-ups. Use these strategically when you're in a tight spot or to maximize your score. Don't waste them on easy clears.
Learn Block Shapes: Over time, you'll become more familiar with the different block shapes and instinctively know where they best fit or what kind of gaps they create.
No Time Limit (in Classic Mode): Take your time! There's no rush in classic mode, so think carefully about each move.
Block Blast! is a fantastic game for both quick casual play and more focused strategic thinking. Enjoy the challenge of clearing those blocks and aiming for new high scores!
