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.

Space planning

Block Blast Shapes and Space Guide

Shape dimensions matter because a large empty-cell count can still hide narrow or disconnected spaces that cannot accept the current fixed piece.

Provisional presets used by the solver

These presets come from production data and are grouped by family. Each card shows the exact fixed orientation, width × height, and occupied-cell count passed to the solver.

Fixed orientation and custom input

The solver does not rotate or reflect a piece automatically. Use the 5×5 custom editor when the current shape or orientation is not represented by a preset, then review the exact occupied cells before solving.

Evidence boundary

This is a provisional convenience list, not an official complete shape inventory. It makes no claim about production frequency, tray generation, rotation controls, or whether a future game version will use the same pieces.
