Warm-Up on the Risers — Daily puzzle for 2026-10-19

Very Easy — logic-grid deduction puzzle

Hugh, Opal, Horace and Nell got in an early warm-up before the rest of the village choir arrived.

The rest of the village choir wasn't due for a while, so Hugh, Opal, Horace and Nell came early to warm up. Four music folders sat waiting on the piano, each a different color. Every singer picked up one folder and stepped onto a riser of their own while the conductor hunted for the opening note. The risers counted up from the lowest, so the first riser was the bottom one and the fourth was the top.

Clues

  1. Of Hugh and Opal, one stood on the first riser and the other on the second one.
  2. Opal's riser was the one right above Hugh's.
  3. Nell ended up higher than Horace.
  4. Of the singers on the first and second risers, one held the red folder and the other held the white folder.
  5. The red folder was on a lower riser than the white folder.
  6. Whoever stood on the fourth riser was not holding the green folder.
