When to Save the Single Block in Block Blast
The single block is the most flexible piece and one of the easiest to waste. Its best value comes from precise finishing moves.
Quick answer: Save it when a row or column is missing one cell, when a crossing point is available, or when it can repair an isolated hole.
Three high-value uses
- Complete a row-column crossing point.
- Fill a cell other shapes cannot reach.
- Trigger an emergency safety clear.
When not to use it
If the move does not advance a clear or repair the board shape, place restrictive pieces first.
Avoid creating another single-cell hole
A good single-block placement should smooth the board or immediately clear a line.
