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 diagnosis

Block Blast No Moves Left? Check the Current Tray

A crowded board can look blocked even when one piece still fits. Exhaustive checking separates “nothing fits now” from “not all three fit in sequence.”

Open the solver

Four honest result categories

  1. Invalid input means the reviewed board or tray cannot be evaluated under the selected profile.
  2. Complete sequence means all three current pieces have a legal ordered path.
  3. Partial legal prefix means one or two pieces can be placed, but no complete three-piece path exists.
  4. No legal first move means none of the three entered pieces fits the current board.

Original engine fixture

The exact input checked

This project-owned board and these three fixed pieces are passed to the production solver unchanged.

Piece 1
square-2

Piece 2
horizontal-2

Piece 3
vertical-2

Production solver result

No legal first move

The checkerboard fixture returns no-first-move after exhaustively checking every legal top-left position for all three pieces.

Evidence boundary

This diagnoses only the entered current tray under provisional-classic-v1. It does not predict an official game-over state, revive or ad behavior, piece refresh, a future tray, or platform-specific UI.
