Turing Machine

Sequence of Play

All players act simultaneously each round.

1. Compose Your Proposal

Overlay three different-colored punch cards to form your proposed code.

2. Question Verifiers

You may question up to 3 Verifiers. For each: place the Verification card under your proposal and mark the result on your note sheet.

3. Deduce

Return punch cards to the support. Write down your deductions on your note sheet.

4. End of Round

On the count of 3, everyone simultaneously shows:

• Thumbs-up - you believe you have found the code.
• Thumbs-down - you have not yet found the code.

5. Verification

If anyone showed thumbs-up, check the solution in the rulebook or app.

• If more than one player is correct: the winner is whoever used the fewest questions. If still tied, all tied players win.
• If a player is incorrect: they are eliminated from the game.

Tips

You do not have to question 3 Verifiers each round. Questioning fewer Verifiers gives you an advantage if you are the first to find the solution - fewer questions asked means a tiebreaker win.

You may question the same Verifier with different proposals across multiple rounds to gather more information.
