A Daily Riddle as a Puzzle Format
Some riddles invite a direct deduction; others depend on re-framing the question or noticing an assumption. “Lateral thinking” is a common label for the latter style of puzzle. It describes a format, not a guarantee about creativity or problem-solving ability.
This is a background explainer on riddle mechanics. To choose a current app for that routine, use the daily-riddle app decision guide, which covers the product fit and practical limits separately.
Try the three original website riddles below. Each has an answer and an explanation that you can reveal when ready. These examples are separate from DailySphinx's current in-app daily puzzle.
One Puzzle at a Time
DailySphinx uses a daily cadence alongside a larger riddle journey and optional modes with different pacing. The central question is whether a person wants one explained riddle, a longer sequence, or a different kind of puzzle session—not whether a game can measure or improve cognition.
DailySphinx is an entertainment puzzle, not an assessment or a cognitive-training program.
For a decision-oriented overview, read the daily-riddle app guide or compare the daily-puzzle app collection. Current provider details are deliberately separate: use the DailySphinx iPhone and iPad edition or DailySphinx Android edition before installing.
Three original website riddles
Try each question before revealing its answer. These website examples are not the app's current daily puzzle.
1. The delivery labels
Three parcels belong to Ada, Ben and Cora. Each parcel has the wrong name on its label. The parcel labelled Ada belongs to Ben. Who owns the parcel labelled Ben?
Reveal answer: The delivery labels
Cora.
Ben's parcel is already the one labelled Ada. If the parcel labelled Ben belonged to Ada, the remaining parcel labelled Cora would correctly belong to Cora, contradicting the rule. So the parcel labelled Ben belongs to Cora, and the one labelled Cora belongs to Ada.
2. The train carriage
In a straight row of train carriages, a green carriage has exactly two carriages ahead of it and exactly three behind it. How many carriages are in the row?
Reveal answer: The train carriage
Six carriages.
Count the two ahead, the green carriage itself, and the three behind: 2 + 1 + 3 = 6. The question counts carriages, so a locomotive is not an extra carriage.
3. The numbered pages
A writer copies two consecutive numbered pages from a notebook. Their page numbers add up to 47. What are the two page numbers?
Reveal answer: The numbered pages
23 and 24.
Consecutive numbers differ by one. Subtract that extra one from 47 and divide by two to get the smaller number: (47 − 1) ÷ 2 = 23. The next number is 24, and 23 + 24 = 47.
