How to play

The one rule

Lamps hang above a paper stage. Cut-out pieces float between the lamps and the paper. Every piece casts a real shadow from every lamp:

  • Move a lamp and its shadows swing the other way.
  • Lower a lamp and its pool of light shrinks while its shadows grow.
  • Higher pieces cast bigger shadows. Hover over a piece to see its height.
  • With several lamps, a spot is only truly dark if every lamp is blocked there.
  • Coloured lamps mix, like stage lights. A shadow takes the colour of whichever lamps still reach it.

Shadow Theatre · co-op

Match the Target card in the corner. The dashed chalk line on the paper traces it too. The meter scores how closely the light and dark match. Hold a score long enough to earn bronze, silver or gold. Stuck? Hint paints cyan where you need more darkness, red where there's too much, and violet where the colour is wrong.

Colour Claim · versus

Your lamp follows you. A bud blooms for you after 3 seconds of light in only your colour. If another colour touches it, your progress pauses but isn't lost. Grab a piece to shade a rival's bud. Twin buds need exactly two colours and give +2 to both. If two people grab the same piece, it's a tug-of-war. Phone players get a secret mission worth +3. First to 12, or the most points when dawn arrives.

Shadow Charades · party

The puppeteer sees a secret word on their phone, or presses next while everyone else looks away. They shape it from shadows while the room shouts guesses. When someone gets it, the puppeteer taps Got it and picks who guessed. Both score.

Phones · how joining works

Scan the QR code in the lobby. Phones need the game to be served, not opened as a file: run start-local on this computer (works offline on your own Wi-Fi), or put the folder online. Phones and this computer must be on the same Wi-Fi for the local server. If your Wi-Fi blocks devices from seeing each other, use a phone hotspot instead.
