About Boltwork: Screw Puzzle
Boltwork is a calm screw puzzle. Plates are stacked on a steel pegboard, each one held down by screws. Move the screws into free holes, and every plate with nothing left holding it falls away. Clear the board to take the machine apart.
Tap a screw to lift it, then tap a free hole, or drag it straight there. A screw with another plate lying on it cannot be lifted, so the order matters. Run out of free holes with plates still on the board and you are stuck, so plan each move before you make it.
• 120 levels, from two plates to fourteen, every one checked solvable
• A daily board, new each day
• Stars for clearing a board in the fewest moves
• Glass plates that show the screws hidden underneath
• Wood, candy and glass plates, and brass, black, copper and gold screw heads
• Coins from every level to spend on the collection
The first level shows each move with a hand. The plates grow from two to fourteen, and the later boards need real planning.
Plays offline, no account needed. Free with ads: an ad now and then between levels, never during play, and optional ones you can watch to drill an extra hole, undo a move, rewind when you are stuck, or double your coins. No purchases.
Lift the first screw and see how the machine comes apart.
