BlockU

BlockU is a calm, elegant logic puzzle.

Place polyomino blocks onto a grid so that each row and column matches its target count. Sounds simple — until the targets demand specific colors, blocking cells split your space, and the only way through is rotating that one awkward Z-piece.

🧠 What Makes It Different

BlockU isn't a Tetris clone or a falling-blocks game. It's a constraint puzzle — you're solving a system, not racing a clock. Every level has a designed solution, but most have several valid paths to it.
