What does this generator produce?

It selects a complete puzzle with its own prompt, constraint structure, hint, answer, and transferable lesson. The reasoning type changes the operation to practice, while difficulty changes the number or indirectness of the required steps. Filters choose among real entries. They do not insert keywords into one repeated puzzle.

Every label is wrong

Three sealed boxes are labelled APPLES, ORANGES, and MIXED. Every label is wrong. You may draw one fruit from one box without looking inside. How can you label all three boxes correctly?

How the generator is designed

The generator draws from individually written challenges rather than swapping keywords into one template. Each item is tagged by the reasoning it practices, checked for a defensible answer, and paired with an explanation of the transferable method. The type filter changes the reasoning operation, while difficulty changes the number or indirectness of the steps.

Use it for deliberate practice

Write a solution before revealing the answer. If you miss, identify whether the failure came from an unstated assumption, a missed constraint, an untested branch, or a weak final check. Generate another challenge of the same type and apply the corrected method without looking back at the first answer.

Check more than the final answer

A correct guess is not yet a reusable skill. Record the decisive observation, show why competing answers fail, and test every condition in the prompt. For an open real-world case, list multiple explanations and name evidence that would distinguish them instead of forcing one conclusion from incomplete facts.
