Rune Brickworks
Forge three magical recipes on the central 3×3 brickwork. A beam stencil covers three straight cells; an elbow covers three corner cells. Tap the TOP-LEFT of the rotated stencil to impress it: covered bricks toggle ON or OFF, so overlapping impressions erase light. Match the recipe diagram exactly, then Forge. Switch stencil, rotate and undo freely. The outside border is not printable. No automatic defeat.
Tap tiles, or use Tab and Enter. Arrow keys move board focus.
