A square fits in the middle of an empty area, so placing it there feels safe. The harder question is whether that move leaves useful space for the next two pieces. GridSmash is played on a 10×10 board with three regular pieces in each tray. A new tray arrives after those three have been placed. You can choose their order and rotate their shapes, so read the whole tray before committing.
Count shapes, not only empty cells
Ten scattered empty cells cannot necessarily hold a five-cell bar or a 2×2 square. Look for continuous lanes and rectangular spaces. Before placing a small piece into a convenient gap, check whether a larger piece has only one suitable location. Reserving that space is often more useful than making the board look tidy.
Rows and columns clear when every cell in the line is occupied. A clear creates fresh space immediately. Blocks do not need to share a color. The placement preview helps you inspect the lines a move will complete; pause on it long enough to check the remaining pieces as well.
A square worth 240 points
In this constructed board, rows 1 and 2 each have their first eight cells occupied. Their final two cells are empty. One ordinary block remains at row 10, column 1; every other cell is empty. Your selected piece is an ordinary 2×2 square. Assume the clear streak starts at zero, no Shatter Zone is active, and no frozen or special blocks are involved.
- Place the square with its upper-left cell at row 1, column 9. Its four cells occupy the two gaps in each of the first two rows.
- The placement adds 4 × 10 = 40 points. Both rows become full in the same move.
- The two-line clear adds 2 × 100 = 200 points at the initial streak multiplier of ×1. The total gain is 240 points.
- Only the block at row 10, column 1 remains. Because the board is not empty, this example does not receive the 5,000-point perfect-clear bonus.
Compare that with a legal but less useful move
You could place the same square in the middle of the board. That move is legal and earns the same 40 placement points, but clears neither row. You would have 21 occupied cells instead of one, and the two narrow gaps would still need filling. The difference is not a hidden penalty: it comes from using the current shape to finish two nearly complete lines.
This does not make every immediate clear the best long-term choice. A small clear can sometimes consume the only space available to another piece. In a normal round, mentally place all three current shapes, applying any line clears between them. If the second piece no longer fits, reconsider the first placement before dropping it.
Understand bonuses without chasing them blindly
Consecutive placements that clear lines build the clear streak; a placement with no clear resets it. The line-score multipliers progress through ×1, ×1.5, ×2, ×3 and then ×5. The multiplier applies to the line-clear points, not every point on the screen. Clearing an active Shatter Zone row can add a further ×3 line-score multiplier. These conditions are why two visually similar clears can produce different totals.
Special blocks also change the plan. Frozen cells need two separate clear events to disappear, so a completed line may not leave an entirely empty lane. A crystal can remove nearby occupied cells. Inspect the resulting space instead of assuming a normal row-clear pattern. A hint offers a legal placement to try; it is not proof that the move maximizes your eventual score.
Practice one decision at a time
In your next Classic round, stop at each new tray and identify its hardest shape to fit. Find a place for it, then check what the other two pieces can do. After every clear, count the long lanes and 2×2 spaces you have recovered. For an additional challenge, compare two candidate orders before placing anything. Your goal is to explain why one order preserves more options, not to promise a particular score from unknown future pieces.
