Numerus Strictus Logicae is an uncommonly difficult I.Q. test comprising 36 numerical puzzles of strict logic which, in order to solve, require keen observation, deep insight and no knowledge beyond addition, multiplication, subtraction and division.
Moreover, I have spent thoughtful effort embedding clues within each puzzle, aiming to make solving a step-by-step deductive process, without employing complex calculations, so as not to require the use of a calculator.
