Screenshot beta with editable review: the core 8×8 rule is confirmed, while recognition coverage, piece refresh, and line-clear timing still need more device evidence.

Current-tray planning

Block Blast High Score Strategy

A useful high-score plan weighs immediate line clears against the room left for difficult shapes. This page shows a real input where the two available strategies disagree.

Open the solver

Plan the current three pieces first

Check all three fixed pieces together instead of committing to the first legal move. A clear can help immediately, but a move that creates small isolated gaps may make the remaining tray harder to place.

What the disagreement shows

Balanced clears two lines and finishes with 38 empty cells, while Survival accepts one clear to preserve six critical-shape fits. Neither answer is a universal scoring trick: each ranks this exact reviewed tray under a named provisional priority.
