How to play

Every day there is one 6×6 factory and one thing to produce. Connect the deposits to the output, press Run, and watch it work.

Building

  • Pick a component, then tap a square to place it.
  • Tap a component you placed to turn it a quarter turn.
  • Choose Remove and tap a component to take it back.
  • On a keyboard: move with the arrow keys, place or turn with Enter, and use the buttons below the board for the rest.

The components

Deposit
Pushes out a resource every couple of ticks, always in the direction it faces. Some deposits hold a limited amount — when the number runs out, that is all you get.
Belt
Carries one resource, one square, in the direction it points. A belt takes resources in from any side except the one it points at, so corners need no special piece — just turn the belt.
Splitter
Resources enter the stem and leave alternately from the two sides. If one side is backed up, the splitter sends everything the other way until it clears.
Merger
Combines up to three incoming lines into one. It takes turns between them, so no line is left waiting while another hogs the route.
Maker
Holds ingredients until it has a full recipe, works for a moment, then pushes the finished product out of the side it faces. It will not take anything in through that side.
Output
Accepts the product you were asked for and counts it. Anything else is turned away and will back up behind it.

Stars

One star for making it work. Two for doing it inside the component budget. Three for matching the tightest build we know of. Solving it is the achievement — the other two stars are the reason to come back to a factory that already works.

A new one every day

Everyone in the world gets the same puzzle, and it changes at midnight UTC. Your board, streak and statistics are stored on your own device — there is no account and nothing to sign up for.
