Block Blast strategy
Block Blast has empty cells, but no piece fits: what to check
Empty cells do not help unless their arrangement fits a piece. A checkerboard can have 32 empty squares and still offer no placement for a domino, an L of three cells or a 2×2 square.

Check the actual shapes
Compare the shape, orientation and position of every occupied cell with the game. A single incorrectly entered square can change the answer. Use the 5×5 shape editor if the piece is missing from the presets.
Try the complete tray
A piece that does not fit now may fit after another piece clears a line. Search all three pieces together instead of checking only the largest.
Read the search status
A completed search with no legal move means no entered piece fits under the supported rules. A completed search with only one or two moves means no sequence places all three. A time-limited search has not proved either conclusion; it only reports what it found.
Know when this tool does not apply
Special tiles, a different board size or a mode with extra rules need a different model. If the input matches and the search is exhausted, the planner cannot create a legal move by inventing an extra piece or rotating one.
