Circuit Mason

Power three sectors with one, two, then three permanent ★ anchors. Each anchor needs BOTH a full row and a full column through it. Full lines remove ordinary blocks but leave anchors in place. An anchor remembers its row charge as ─, column charge as │, and both as +. All anchors showing + completes the sector and opens the next layout.

The tray contains a domino, elbow and bar. Use each once before all three refill. Choose a shape, rotate freely, select its top-left anchor square and Place. The mint outline previews the footprint. Each sector allows twenty placements and starts with two salvage fuses. Select an ordinary block and Salvage to remove it, spending one fuse AND one placement; permanent anchors cannot be removed.

Completed sectors refresh the budget and fuses. Blocked placements spend nothing. Retry repeats these three puzzles; improve total placements and score. Arrow keys aim, Enter selects. Shape buttons and actions support touch.
