Logical Reasoning

Deduce what must, can, or cannot be true from a set of ordering rules. Often described as among the hardest because of the time pressure.

What it measures

Deductive reasoning. You are given rules that constrain an arrangement and must determine which conclusions follow.

Reported format

Scheduling or ordering puzzles with a short list of constraints, then questions of the form which arrangement could be true, cannot be true, or must be true.
The time limit is commonly cited as 20 minutes, and the count is debated as roughly 15 to 18 questions.
As with reading, no scratch paper is provided.

Disputed or unconfirmed

The exact question count (about 15 versus about 18) and whether backtracking is allowed.

How to practice

Translate each rule into a concrete restriction before looking at the options, and eliminate arrangements that any single rule forbids. For must-be-true questions, look for the conclusion that holds across every arrangement the rules allow, not just one.

How this tool handles it

Each puzzle is generated by enumerating every possible arrangement and keying the answer against the set that satisfies the rules, so could, cannot, and must be true are provably correct rather than asserted.
A no-backtracking fidelity mode mirrors the reported constraint, and a written explanation appears in review.
