## Rules questions

### Can I change my 3-card proposal between asking different Verifiers in the same round?

No — you must keep the same proposal for the entire round while you question up to three Verifiers, and record that proposal and all answers on your note sheet (p. 3–4).

### How many Verifiers can I question each round — do I have to ask three?

You may question a maximum of three Verifiers per round but you can ask fewer if you wish; you must record the answers you do get as they count toward tie-breaking (p. 3–4).

### If a Verifier gives me a ✓, does that mean the revealed number equals the value I showed (e.g., 'it's 3')?

No — a ✓ only means your proposal satisfies the Verifier's hidden criterion (for example, “greater than 1”); it does not reveal the exact value shown in your proposal (p. 3–4).

### What happens when someone says they’ve found the code — how do we verify and decide the winner?

Players who think they found the code write it secretly and check the Solutions section or the app; if multiple players are correct the one who asked the fewest questions wins (ties share the win), and incorrect guessers are eliminated while the game continues for remaining players (p. 3).

### Do I need to identify every Verifier’s criterion to solve the puzzle, or are some criteria optional?

All Verifiers are essential and none repeat another's information, so you will need the criteria of every Verifier to determine the unique code (p. 3–4).
