Block Cast for Flipper Zero

A Block Blast-inspired puzzle game for the Flipper Zero. Place pieces on an 8x8 grid and clear full rows and columns to score points.

How to Play

You receive 3 random pieces each round. Place all 3 on the 8x8 grid before receiving new ones. Any completely filled row or column is cleared automatically. The game ends when no remaining piece can fit on the board.

Pieces

19 piece types: single blocks, horizontal/vertical lines (2-5), 2x2 and 3x3 squares, small L-shapes, and large L-shapes.

Scoring

• Placement: 1 point per cell in the placed piece
• Line clears: 10 x (lines cleared)^2 — clearing multiple lines at once gives a combo bonus
