# Reserve the footprint: a three-piece block puzzle worksheet

Prepared on behalf of blockblast.co. This is a practical planning sheet for its independently made browser puzzle, not an official Hungry Studio guide. Checked 22 October 2026.

# Before dragging a block

Write down each piece’s width and height in its displayed orientation. In the browser game at blockblast.co, pieces do not rotate, and every occupied cell must fit inside the 8-by-8 board. Nine separate empty cells are not the same as one empty 3-by-3 square.

# A four-question turn review

1. Which remaining piece has the fewest legal positions? Mark its exact footprint mentally.
2. Can another piece finish a row or column and open that footprint? Consider the board after the clear, rather than just the board before it.
3. Will a convenient small placement occupy a cell the difficult piece needs? Keep that cell available until the larger piece is placed.
4. After the first two moves, can the final piece still fit? Check the complete sequence before committing.

# Record one turn

Board observation: ____ Difficult piece and required footprint: ____ First placement and resulting clear: ____ Second placement and resulting clear: ____ Final piece location: ____ What would fail in the reverse order? ____

The purpose is to compare sequences, not to apply an automatic largest-piece-first rule. A smaller piece may need to clear a line first. Repeat the worksheet for one crowded board, then describe the space you deliberately preserved.

# Check a difficult position

Use the site’s placement solver by entering the current board and one to three remaining pieces manually. Verify every occupied cell and each piece before following a suggestion. The helper suggests placements and clears; it does not predict the next tray or reproduce game scoring. Keep scores from this independent web game separate from scores in Hungry Studio’s app.
