How this list was compiled: Puzzles written for this site on 2026-10-02: 200 in four sets of 50, each one or two short sentences with three answers to choose from. The number and word patterns of What comes next? and the clues of Who is it? were solved by rule on 2026-10-02: a pattern goes on in one way only (the same step for numbers, the same repeat for words), and the two clues of a Who is it? puzzle leave one order of the three. The puzzles of Odd one out and If, then were read with each of the three answers in place, and any puzzle that could be argued two ways was left out. No published worksheet, puzzle book or program was copied. Licence: own work
