Five puzzles where the rule is the thing you are looking for. Axiom hides one rule and gives you a handful of tests to tell five candidates apart. Suffice is data sufficiency: two statements and a verdict on whether they settle it. Docket is the analytical reasoning section of a well-known test: one setup, five questions. Stands hands you a few surviving facts about a round robin and asks for the whole table back. Ergo gives you a few if-then rules and one fact, and you sort nine statements into must be true, could be true and cannot be true.
Axiom is the one nobody else has: one hidden rule splits the board, and each test you run has to buy you the most information. Suffice is the reasoning section of a well-known test: eight questions you never answer, two statements each, and you say whether they settle it. Stands is deduction from a results table: everyone played everyone once, and the surviving facts pin every result.
On how many tests it took you to name the rule. Fewer is better.
It is the analytical reasoning shape, one setup and five questions, written fresh every day.
