Piecework: Block Puzzle

Trace a thread. Plan the landing. Clear the lines.

Piecework is a casual block puzzle with two twists: you never drag a piece or choose where it goes. You build it on a 4×4 panel, and the piece finds its own place on the board.

How it works
Slide a finger along the active cells of the panel to link 3–5 of them into a shape. Release, and the piece flies onto the board and settles into the spot a solver picks. While you trace, a dotted aim shows the flight path and the landing spot, and it shifts with every cell you add. After each move the used cells fade out and fresh ones grow beside them.

Puzzle mechanics
• Thread — trace a line through active panel cells to build a piece of 3–5 cells
• Dotted aim — preview the flight path and landing spot as you trace
• Rising pieces — shapes enter the board from below and travel upward
• Relief rows — rows with a shifting gap roll in from above on the level's schedule and push the stack down
• Line scoring — points come only from cleared lines; several lines in one move are worth more than the same lines cleared one by one, and back-to-back clears build a combo multiplier
• Crystal goals — crystals sit on panel cells, ride onto the board with the piece and are collected when their line clears

Flowing, thoughtful play
Each level asks you to reach a score or collect crystals, and some levels call for 30–50 crystals at once. You lose if the relief pushes the stack to the bottom or if no piece has room left, so every thread is a small plan. Levels run in a stream with no level-complete screen: the stack slides up and the next board rolls in from above. Because the aim updates as you trace, you can read the board before you let go.
