Choose the missing rules. Match every output test.

Rules & strategy

Each gate combines two incoming signals. BOTH lights only if both are on; EITHER lights if at least one is on; DIFFERENT lights if exactly one is on. Rules may be used more than once. A gate can feed several later gates. Set every gate so both outputs match all eight tests.

Start with tests that separate the rules: 0 + 1 separates BOTH from the other two; 1 + 1 separates DIFFERENT from the others. Follow shared gates forward and reason back from the required outputs. A green test fits your current network; it does not confirm each gate individually.

36 original unique-solution networks, with 4, 6 and 8 gates. Upper packs have deeper dependencies and require both outputs to narrow down the solution. Difficulty is structurally checked, not independently player-tested. Daily rotates this bank at 00:00 UTC; refresh for a new day. Progress lasts for this visit. No timer or lives.

Rules & example: Signal Workshop
  1. Each gate combines two signals using BOTH, EITHER or DIFFERENT. Rules can repeat.
  2. Set every gate so both final outputs match all eight input tests. A gate may feed several later gates.
  3. Click a rule, or use arrows to select a gate and 1–3 to set it. Delete clears a rule; U undoes.

A quick example

With one input on and the other off, BOTH gives off; EITHER and DIFFERENT give on. When both inputs are on, only DIFFERENT gives off. Combine these clues across the network.

Where to start

36 original, unique-solution networks in 4-, 6- and 8-gate packs. Upper packs require deeper shared dependencies. No timer or lives. Daily rotates this bank; progress lasts for this visit. Difficulty is structurally checked, not independently player-tested.
