We introduce a large family of combinatorial objects, called standard puzzles, defined by very simple rules. We focus on the standard puzzles for which the enumeration problems can be solved by explicit formulas or by classical numbers, such as binomial coefficients, Fibonacci numbers, tangent numbers, Catalan numbers, $\ldots$
Determinants of (generalised) Catalan numbers
Continuous Analogues for the Binomial Coefficients and the Catalan Numbers
On some binomial coefficients related to the evaluation of tan(nx)
