The best move in Block Blast is one that maximizes space and clears multiple rows at once, creating room for future placements. Prioritize Combo Clears by aligning blocks strategically, and always leave space for larger pieces to avoid getting stuck. Planning ahead and using Perfect Fit placements will help maintain an open board, ensuring smoother gameplay. Mastering these techniques, just like following Block Blast Rules, will significantly improve your chances of winning and achieving high scores!
