Analytical Puzzles & Arrangements

Sixteen constraint puzzles: seating and sequencing deductions worked from clue sets with unique solutions, plus the classic reasoning set — river crossings, the all-labels-wrong boxes, jug measuring, knockout counting, committee constraints and truth-teller setups (including one whose correct answer is that NOTHING further follows). Solvers who write the constraints down beat solvers who juggle them mentally, which is exactly the discipline being measured. 25 minutes.
