Screw Workshop

About the game

An original browser game by Zarocer.

One plate, three screws and a choice: which should come out first? Screw Workshop is an original puzzle about color sorting and stacked plates. Each exposed screw enters one of two active color trays or waits in four reserve spaces. Three matching screws complete a tray and advance the queue. Clearing a plate reveals the next layer. The workshop contains 24 fixed challenges. Early puzzles introduce the rules at a gentle pace; later boards add colors and deeper layers that reward looking ahead. The daily challenge uses the UTC date to generate the same puzzle for players using the same generator version. There is no time limit and no advertising inside the game. Hints, undo and restored saves remain available for local practice. Personal best times belong to your device. Global ranking is offline in this release candidate.

Controls

Tap or click an exposed screw on the front plate. Trays collect three matching screws and refill from the visible queue. Other colors wait in the reserve and move automatically into compatible trays. Remove all three screws from a plate to reveal the next layer. Release every plate to win. You lose when all four reserve spaces are full and no exposed screw matches an active tray. Use Tab or arrow keys to select screws, then Enter or Space to remove them. Escape opens pause.
