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).

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).

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).

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).

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).
