Block Puzzle
Master

• Desktop: Click and hold a block piece, drag it onto the grid, and release to place it.
• Mobile / Tablet: Touch and hold a piece, drag it to your desired position, then lift your finger to drop it.
• Cancel placement: Drag the piece back to the tray before releasing to cancel.
• Preview: Valid placement cells are highlighted in real time as you drag.

Place block pieces on a 10×10 grid and clear as many rows and columns as possible to earn the highest score. The game ends when none of the three available pieces can fit anywhere on the remaining board — so keeping space available is the key challenge.

• Three shaped pieces appear in the piece tray. You may place them in any order.
• Drag a piece from the tray to any valid empty area on the 10×10 grid.
• When a complete row or column is filled, it clears automatically and you earn points.
• Once all three pieces are placed, a new set of three pieces appears.
• Continue placing pieces and clearing lines to prevent the board from filling up.
• The game ends when no piece in the current set can be legally placed on the board.

• Single line cleared: Base points equal to the number of blocks in the line (10 cells = 10 pts).
• 2 lines at once (combo): Bonus multiplier applied — much more rewarding than two separate clears.
• 3+ lines at once: Higher multiplier — the bigger the combo, the bigger the reward.
• Placement alone: Does not award points — only clearing lines scores.

💡 Key takeaway: Always set up multi-line clears rather than clearing lines one at a time — the score difference is dramatic.

• 1×1 single block: Most flexible — use it to fill any isolated gap.
• 1×2 / 1×3 bars: Best for finishing nearly-complete rows or columns.
• 2×2 square: Ideal for filling large open spaces early in the game.
• L-shape / J-shape: Corner-friendly — place in grid corners to save central space.
• T-shape: Versatile but requires care to avoid awkward gaps.
• S-shape / Z-shape: Most challenging — plan their position before placing.

1. Keep the Board Open — Avoid clustering pieces in one corner. A nearly full board is very hard to recover from.

2. Plan Two or Three Moves Ahead — You can see all three pieces before placing any. Use that to set up multi-line clears.

3. Clear Rows and Columns Simultaneously — A single piece that completes both a row and a column at once triggers a high-value combo.

4. Use Corners and Edges First — Place L/J-shaped pieces in corners early. Keep the center open for late-game flexibility.

5. Treat Each Set of Three as a Unit — Plan the placement sequence for all three pieces together before touching any of them.

6. Take Your Time — No time limit means there's never a reason to rush. Every move matters.

• Isolated single-cell gaps: Gaps that no piece can fill are dead space — avoid creating them.
• One-sided filling: Piling pieces on one side leaves the other side unused and hard to manage.
• Ignoring columns: Columns score just as much as rows — balance your clearing in both directions.
• Large pieces in center early: Reserve the center for small or late-game pieces.
• Reactive placement: Always think about downstream consequences, not just where a piece currently fits.
