- Place the machine tile in the center of the table.
- Arrange the punch cards in the caddy (1s in front, 2s next, etc.)
- Choose a problem to solve. You can use 1 from the rule book or go to turingmachine.info for more problems to solve.
- Place the criteria cards in front of their matching letter on the machine tile. e.g. "A" with "A".
- Place the verification cards face down next to their criteria
cards and mark the associated letter matching the machine tile.
- Note that each verification card can be used for 4 different numbers and 4 different colors!
- Give a player aid/screen and a note sheet to each player. If playing a game from the website, be sure to write down the game number.
- Each player should draw a line through any unused columns on their sheet. e.g. In problem "01", you would cross off columns "E" and "F".
The game takes place over a number of rounds (it's a race) until 1 or more players have found the code (see game end for more info).
The following steps, except #4, are done simultaneously in a round:
- Compose
- Question
- Deduce
- End of round (when everyone has completed steps 1-3)
- Compose
- Compose your 3 digit proposal by overlaying 3 different
colored cards.
- If the card you are using is in use, simply wait until it's available.
- Compose your 3 digit proposal by overlaying 3 different
colored cards.
- Question
- You may question up to 3 verifiers during a round without changing your proposal. e.g. You can ask up to 3 verifiers, but you cannot change your number you are verifying during the round.
- Place the verifier's verification card under your proposal,
making sure it is properly lined up with the punch cards using
the "target" symbols in the corners.
- Each verifier will tell you a pass (✓) or (X) fail.
- Mark an "X" or "✓" in the corresponding space on your note sheet.
- Note: Your proposal and the verifiers you question are open information, but your answers and notes are secret.
- Deduce
- Put your punch cards back in the caddy and analyze your answers.
- Make notes/deductions on your note sheet and determine if you have found the code.
- End of Round
- After all players have finished steps 1-3, proceed.
- Everyone extends a closed fist.
- On the count of 3, everyone either points upward or downward.
- Pointing upward indicates that (you think) you have found the code. Proceed to the game end instructions to verify.
- Pointing downward indicates you have not yet found the code.
- If no one has found the code, proceed to the next round.
- If 1 or more players have found the code during a round, they should secretly write it on their note sheet.
- Those that put a thumb up during the end of round
phase will check their answers.
- If someone has the correct code, they win!
- If more than one person has the correct code:
- The person that asked the fewest number of questions wins (count the number of "X" and "✓" marks on the note sheet).
- If still tied, the players share the victory.
- If no one has the correct code, all incorrect players are eliminated from the game. If any players remain, the game continues.
- Cleanup reminder: Don't forget to remove the ✓ from the verification cards!
Symbol Clarification 
(Card 1) To pass, you must find if the △ number is >= 1. Watch out: If your △ proposal is 3 and the answer is ✓, it does not mean the answer is, just that the number is > 1 (not equal to it). 
(Card 2-4) Similar to card #1, but there are 3 possibilities. The △ number can be <, =, or > the number indicated. Watch out: If the △ proposal is "2" and you get ✓, this does not mean the number is 2, it only means it must be < 3. 
(Card 5-7) Find if the △ number has to be even or odd. 
(Card 8-10) The verifier verifies that there is a precise number (that they now) of 1s in your proposal. e.g. they can verify that there are 2 (no more, no less). The code could then be 113, 151, 411, etc. 
(Card 11-13) These work similarly to Cards 2-4, but instead of comparing with a specific number, you are comparing against another number in your proposal e.g. △ with □ 
(Card 14-15) The verifier verifies that the number of a particular color (that they know) is smaller than all the other numbers. 
(Card 16) This verifies that there are more of either even or odd numbers in the code. 
(Card 17) This verifies that there is a precise number (that they know) of even numbers in the code (0, 1, 2, or 3). 
(Card 18) This verifies that the sum of all the numbers in the code is either even or odd. 
(Card 19) This works like cards 2-4, but this compares the sum of the △ and □ numbers to 6. The sum can be <, =, or >. 
(Card 20) This verifies if a number repeats itself, and if so, how many times. There may be no repetition (e.g. 125), 1 number repeats (e.g. 121), or a number repeats itself twice (e.g. 222). If a number repeats itself, the verifier doesn't know anything about it. It doesn't know the color or its number. 
(Card 21) This verifies that there is either 1 pair of identical numbers or no pairs of identical numbers (e.g. 231 or 333 - which is not a pair). If there is a pair, the verifier does not know anything about it, as in the color or number. 
(Card 22) This verifies the 3 number are in either ascending order, descending order, or neither. e.g. 223 is not ascending. 
(Card 23) This card works in the same way as Card 19, but the verifier compares the subm of all the numbers with 6. 
(Card 24) This verifies that in the code there are consecutive increasing values in either a 2 digit (e.g. 312), 3 digit sequence (e.g. 345), or none at all (e.g. 132). 
(Card 25) This verifies that there are either increasing or decreasing values in a 2-digit consecutive sequence (e.g. 312 or 254), a 3 digit consecutive sequence (e.g. 345 or 321), or none at all (e.g. 135 or 531). The verifier does not know if the sequence is increasing or decreasing. 
(Card 26-27) This verifies that the number of a particular color (that they know) is < 3 (e.g. the □ number is < 3). Watch out: If the criteria is "the □ < 3"; the other colors' numbers can also be < 3...the verifier is just not verifying that. 
(Card 28-30) This verifies that the number of a particular color (that they know) is 1 (e.g. △ is a 1). Watch out: The other colors' numbers can also be 1...the verifier is just not verifying that. 
(Card 31-32) This verifies that the number of a particular color (that they know) is > 1. Watch out: The other colors' numbers can also be > 1...the verifier is just not verifying that. 
(Card 33) This verifies that the number of a particular color (that they know) is odd or even (e.g. the △ is even). Watch out: The other numbers can also be even (or odd, depending). 
(Card 34-35) This verifies that the number of a particular color is <= to all other numbers (e.g. they verify that no other color is < □). 
(Card 36) This verifies that the sum of all the numbers in the code is a multiple of 3, 4, or 5. 
(Card 37-38) This verifies that the sum of 2 particular numbers (that they know) is 4. 
(Card 39-41) This verifies that the number of a particular color (that they know) is <, =, or > 1. 
(Card 42) This verifies that the number of a particular color (that they know) is either < or > either of the others (e.g. The □ > the others). 
(Card 43-44) This verifies that the △ is <, =, or > another particular number (that they know). 
(Card 45-47) This verifies that the number of 1s or 3s in the code = a particular number. 
(Card 48) This verifies that the number of a particular color (that they know) is either <, =, > that of another particular color (that they know) (e.g. the □ number > the ○ number).
