Stack six stones in order along a hidden factual scale. Here is how Cairn works, what makes the daily puzzle fair, and why it belongs in Wittora's collection of quick thinking games.
Cairn focuses on one readable core action: stack six stones in order along a hidden factual scale.
How Cairn works
- Cairn focuses on one readable core action: stack six stones in order along a hidden factual scale.
- It asks you to reason with facts, categories and clues rather than simply recall trivia on command.
- A new Cairn puzzle appears every day, and Infinite mode lets you keep practicing the same idea after the daily round.
Rules
- Start from the visible board or clue set and make a move that follows the core knowledge puzzle logic.
- Use the feedback on the screen to narrow the remaining possibilities.
- Win by completing the board, answer, order or hidden target. In Daily mode your result is recorded once; in Infinite mode you can keep experimenting.
Data and puzzle logic
Datasets are compact, curated and deterministic, with clues written to avoid needing a login, feed or live API at play time.
Lore and naming
Cairn is named like a small artifact from the Wittora shelf: compact, memorable and a little mysterious. The lore is intentionally light. The game should feel like a clever object you pick up for a few minutes, solve, share and put back glowing.
Where the idea comes from
It connects quiz culture with newspaper logic, turning facts into a puzzle board instead of a speed contest.
