How to Play the Game "Triptych"

What Is "Triptych"?

There is no widely known game called "Triptych." It may be:

• A local/regional card or board game.
• A niche indie title (e.g., a game jam entry).
• A misremembered name (e.g., Triptych is a puzzle mechanic in The Witness, or Triptych is an art term).

To Identify It, Tell Me:

1. Where did you hear of it? (Friend, stream, article, dream?)
2. Format: Board, card, video, party, RPG?
3. Any rules/mechanics you recall?
4. Number of players? Components (cards, dice, app)?

With details, I can find or reconstruct the rules!
