How to play Screwfall

Every board starts as a pegboard covered in plates. Each plate is held by two to four coloured screws. Your job is to get every plate off the board and into the scrap bin at the bottom. A plate only falls when all of its screws are out — and every screw you remove has to live somewhere: in a free hole. That one rule is the whole puzzle. Space is tight at the start and grows as plates fall, so the order you unscrew in decides everything.

1. Press Play, or open the Workshop Map and pick any board you have unlocked. Board 1 of Pine Boards is open from the start.
2. Tap a screw. It spins out with a whirr and flies to a free hole by itself: a spare socket of its own colour first, then a free board hole, then the magnet tray if it is out, then a plain socket. You score 10 points for every screw parked.
3. Watch for covered screws. A screw with another plate lying over it cannot be touched. The game tells you, and shakes the plate. Drop the plate on top first.
4. Drop plates. When a plate loses its last screw it tips over on that final screw hole, falls with a bounce into the scrap bin and scores 50 points. Drop plates back to back and the falls chain into a combo: the second plate in a chain scores 100, the third 150, and so on.
5. Mind the holes. A fallen plate frees every hole it was hiding: its own screw holes, plus any spare holes drilled under it. If every hole fills up and no screw can move, the board is jammed and you restart it. Every one of the 120 boards has been solver-verified, so a clean line home always exists.
6. Clear the board to earn stars and unlock the next board. Finish all 30 boards of a workshop, collect tools for your tool wall, and come back daily for the Daily Board.

The hole rules

Spare sockets. The rail at the top of the board holds a few spare sockets — three on the early boards, down to just one in Master Joinery. Most sockets are painted: a painted socket only takes a screw of its own colour. A plain grey socket takes any screw. When you tap a screw, the game parks it in the best free spot in this order: a socket of its colour, a board hole, the magnet tray, a plain socket.

Board holes. The pegboard itself is full of holes, but at the start nearly all of them are hidden under plates. A hole opens when every plate covering it has fallen. Board holes are plain — any screw fits, including one-way screws — which is why dropping a big plate at the right moment can rescue a board that looked jammed.

Re-parking. A parked screw is not stuck forever. Tap any parked screw and the holes it may move to glow green; tap one and it hops across. It costs no points. Re-parking is how you free the one plain socket a one-way screw is waiting for, or shuffle a colour out of a socket another screw needs. Two exceptions: screws on the magnet tray are held fast, and one-way screws never move again once parked.

One-way screws. From the Iron Foundry onwards you will meet screws with a yellow chevron. A one-way screw only sits in a plain hole — a board hole, the magnet tray, or a plain socket — never in a painted socket, even one of its own colour. Plan for them early: if your only plain holes fill with ordinary screws, a one-way screw can jam the whole board.

Layered plates. Plates overlap. A plate lying on top covers the screws beneath it, and it also covers the spare holes drilled under it. The fall order is partly forced by the stack: sometimes you must drop a plate you do not care about just to reach the one you do, or to open the holes hiding under it.

The four workshops

Workshop	Boards	What changes	Opens at
Pine Boards	1–30	Light pine plates, 2 to 4 per board, three spare sockets to learn with	Start of the game
Oak Works	31–60	Heavier oak, up to 5 plates, only 2 spare sockets, more colours	24 stars
Iron Foundry	61–90	Iron plates, up to 6 per board, one-way screws arrive, sockets shrink to 1 late on	80 stars
Master Joinery	91–120	Walnut and brass, 6 to 7 plates, a single spare socket, one-way screws everywhere	150 stars

Inside a workshop the boards open one at a time: clear a board and the next one unlocks. The Daily Board is separate — every day it deals one of the 120 boards flipped in a mirror, so the layout feels familiar and wrong at the same time. Clearing it drops a bonus booster into your toolbox, once a day.

Boosters, stars and the tool wall

• Extra Hole. Drills one more plain socket into the rail. Up to two extra sockets per board. The classic way out of a colour jam.
• Power Drill. Destroys one exposed screw where it sits — no hole needed at all. If it was the plate's last screw, the plate falls. It cannot reach covered screws.
• Magnet Tray. Puts a tray beside the rail that holds any three screws, any colour, one-way screws included. Screws on the tray are done for the board: the magnet holds them fast.
• Hint. Not a booster, but it costs 25 points and counts against your stars. The game's own solver finds a full line home from where you stand and glows the first screw of it.

Stars. A clear with no booster and no hint earns 3 stars. One piece of help earns 2. Any other clear earns 1. Stars open the workshops, so clean clears are worth real progress. Boosters live in your toolbox across boards: you start with three Extra Holes, two Power Drills and two Magnet Trays, and every achievement you unlock drops one more random booster in. The tool wall fills up as you play: one new tool for every 4 boards cleared, 30 tools in all, from a claw hammer to the master apron. There are also 20 achievements, from your first dropped plate to the full 300-star set.

Screwfall or Screw Sort Puzzle?

GameOLL has two screw games, and they play nothing alike. In Screw Sort Puzzle, screws come out of metal plates and get sorted into colour boxes: four screws of a colour fill a box, the box closes, and a five-slot buffer keeps you alive while you wait for the right box. That game is about sorting discipline — the wrong screw in the buffer at the wrong time jams you.

Screwfall has no boxes, no buffer and nothing to sort into. Here a removed screw only ever goes into a free hole, and the puzzle is the plates themselves: which plate to drop first, which holes its fall will open, and how to keep a plain hole spare for the one-way screw you can already see coming. If you want a tidier, collection-style challenge, play the sorting game. If you want physics, falling plates and combos, stay here. Plenty of players keep both on the go — and if sliding-block exits are more your thing, Gate Jam and Parking Jam scratch that itch, or browse the full shelf on the Play Games page.

7 tips to clear more boards

1. Start with the top of the stack. Covered screws are dead weight until the plate over them falls. Working from the top layer down is rarely wrong, and every plate you drop opens holes for the next one.
2. Count a plate's screws before you start it. A plate with four screws needs four free holes before it can fall. If you can only see two, drop a smaller plate first and let its fall open the rest.
3. Guard your plain holes. Plain sockets and open board holes are the only homes a one-way screw has. If a board has one-way screws, treat every plain hole as reserved until they are parked.
4. Re-park instead of restarting. A jam usually means one screw is sitting in the wrong hole, not that the board is lost. Shuffle parked screws around before you give the board up.
5. Chain your falls for score. Plates that fall within about a second of each other multiply: 50, 100, 150. If two plates are each hanging by one screw, take both screws out fast and bank the combo.
6. Save the Power Drill for a last screw. Drilling a plate's final screw drops the plate and opens its holes in one move. Drilling a random early screw just wastes the strongest booster you own.
7. Play the Daily Board. It is a mirrored board you may half remember, which makes it perfect practice — and the bonus booster it pays out is free toolbox stock for the hard Master Joinery boards.

Screw pin puzzle FAQ

Is Screwfall free to play?

Yes. Screwfall is 100% free, all 120 boards included. You play it right on this page. There is no download, no sign-up and no payment.

How do you play a screw pin puzzle?

Tap a screw to spin it out of its plate, and it parks itself in a free hole: a spare socket of its own colour, a board hole left by a fallen plate, the magnet tray, or a plain socket. A plate falls into the scrap bin when its last screw comes out, and its fall opens the holes it was hiding. A screw covered by another plate cannot be touched until that plate drops. Clear every plate off the board to finish it.

What is the difference between Screwfall and Screw Sort Puzzle?

Screw Sort Puzzle is a sorting game: removed screws go into colour boxes, four to a box, with a five-slot buffer. Screwfall has no boxes and no buffer at all. Removed screws only ever park in free holes, and the whole game is about dropping plates in the right order so their falls open the holes you need next.

What are one-way screws?

One-way screws appear from the Iron Foundry onwards and carry a yellow chevron. They only sit in plain holes — board holes, the magnet tray, or plain grey sockets — never in a painted socket, even one of their own colour. Once parked, a one-way screw never moves again, so keep a plain hole spare when you see one on a board.

What happens when you run out of free holes?

If every hole is full and no screw can move, the board is jammed and you restart it. Before that point you usually have outs: re-park a parked screw to free the right hole, drop a plate to open new holes, or spend a booster. Every board is solver-verified, so a route through always exists — and boosters you already spent on a board stay spent when you restart it.

Does Screwfall save my progress?

Yes, in your own browser. Your stars, unlocked boards, toolbox, tool wall, achievements and best score all save automatically the moment they change. A board that is half finished when you leave starts again from the top when you come back. Nothing leaves your device, and there is no account to make.
