PIPWORKS: Match the Ends. Forge the Shape.
PIPWORKS is an original portrait-first Domino-End Factory-Chain puzzle. Select a stable domino machine and lay it against one open socket. Matching the tile's left or right end fixes its physical orientation; that orientation changes how its Turner, Shear, Return Press or Ink Wheel transforms the same four stable product quoins.
POSTCOIL: The Body Is the Delivery Line.
POSTCOIL is a standalone, offline, English-first, true fine-pixel **Body-Conveyor Snake Courier Puzzle**. It retains classic cardinal Snake movement, growth, no-reversal and self-collision grammar, then makes growth a stable logistics system. Every collected parcel becomes the same named body link. When the courier head enters a dock, only the neck parcel may unload; every remaining link is physically pulled forward into the freed cell.
GROUTWAKE: Every Matched Pair Becomes the Next Wall.
GROUTWAKE is a standalone, offline, English-first, true fine-pixel **Pair-Match Corridor-Grout Sliding Puzzle**. Every Swipe moves all living animal reliefs in one stable front-to-back order. When identical physical bodies collide, both leave the board—but the moving body's complete travelled corridor, including both start cells, immediately hardens into permanent grout. Later bodies in the same Swipe already treat that new corridor as a wall.
