Casual Game Number Blocks - Classic Puzzle Game

The board does not reorganize scattered gaps automatically. Every placed piece occupies its exact shape until a horizontal row or vertical column is completely filled and cleared. Before moving, inspect all currently offered pieces rather than grabbing the first one and using the nearest opening. A long bar needs an uninterrupted lane, an L or corner piece needs a complete bend, and a bulky shape needs a region without small holes. Place the hardest shape first, then use single cells or short pieces to finish lines. A row missing one cell looks attractive, but filling it may cut the only usable column for a long piece. Compare the practical shape space released after the clear. Keep the center as a flexible working area and build near-complete lines from the edges, but do not raise every border at once and trap the middle inside narrow holes. A placement that completes both a row and column returns much more room, so look for an intersection gap that one piece can fill in both directions. High scores come from preserving a board that continues accepting pieces, not from forcing every current shape somewhere. When several upcoming pieces are visible, preview where all of them can land after the first clear rather than proving only that the first one fits. On a crowded board, choose an immediate line clear even when its single score is modest. Scattered one-cell gaps without a continuous region still mean failure is close. The source data confirms row-and-column clearing, but does not establish adjacent equal-number merging, so that unsupported rule is deliberately excluded.
