A useful decision order for difficult trays
When all three pieces look awkward, work through the tray in this order: identify the piece with the fewest legal positions, find the placements that preserve the largest connected empty area, then check whether those placements let the other two pieces complete a row or column.
Do corners matter?
Corners are useful for shapes that naturally fit an edge, but treating every corner as a permanent dumping area can create deep pockets. The better rule is to keep shapes compact and leave the center connected enough for larger pieces.
When should you use the Solver?
The Solver is most useful when a tray has several plausible placements and you cannot see which order keeps the board healthiest. Upload a screenshot, verify the detected board and pieces, and compare its suggested sequence with your own plan.
What high-score play usually has in common
- Large connected empty regions instead of many isolated gaps.
- A plan for all three current pieces before the first placement.
- Space reserved for long bars, rectangles and square blocks.
- Line clears that improve the next position, not just the current score.
- Patience: a low-scoring safe move can be better than a flashy clear that damages the board.
