Digit Code

For some unknown reason, we now find ourselves in a situation where we must quickly decipher a six-digit digital code. We will analyze this code by gathering various uncertain information. Its meaning will become clear in our hands, just as it always has.

In a Two-player game In a two-player game, each player creates a secret six-digit code with three numbers over three numbers, where the digits 0-9 appear no more than twice and not next to each other. The letters AY are used to indicate number segments in a column or in a row, or within a specific digit. Players take turns asking each other questions of the following four types:

• How many spaces in the row or column are filled?
• Is the number even or odd?
• If you look at the adjacent numbers ? and ??, which is greater?
• Is the segment in row? and column? filled?

Each player must ask all four question types before they can repeat a question type. On a turn, a player can give a six-digit number instead of a question. If they have guessed all six numbers correctly, they win; if not, the opponent says "Wrong" and the game continues. If a player guesses incorrectly twice, they lose.

With three or more players, one player makes up a six-digit number that the other players race to deduce first, with players taking turns asking questions. Again, if a player guesses incorrectly twice, they are out of the game.
