Question 1

What is Deduction?

Accepted Answer

A logic game: several clues describe one secret number, and you pick the single candidate number that satisfies every clue by eliminating the ones that break a clue.

Question 2

How do I solve a round?

Accepted Answer

Read each clue, then test every option against all of them. Cross out any number that breaks even one clue · the one number that survives every clue is the answer.

Question 3

What kinds of clues appear?

Accepted Answer

Parity (even / odd), range (greater or less than a value), multiples (is or is not a multiple of a small number), the digit sum, and whether the number has two digits.

Question 4

Can I print it as a worksheet?

Accepted Answer

Yes. Deduction supports the printable worksheet generator · the clues and numbered options print on paper with an answer key, since the whole puzzle is text.
