This week the #puzzle is: Can You Hop Around the Chessboard? #chess #combinations #coding A frog is hopping around a chessboard, always from the center of one square to the center of another square. Each square has side length 1, but the board itself is not necessarily 8-by-8. Instead, it’s N-by-N, where N is some […]

This week the #puzzle is: Have You Heard the Buzz? #counting #frequency #combinations I recently introduced my children to a game called “Buzz” (also known as “Fizz buzz”), in which players take turns reciting whole numbers in order. However, in one particular variant of the game, anytime a number is a multiple of 7 or […]

This week the #puzzle is: Can You Rile and Grace the Polyhedron? #geometry An alien—more specifically, an Eridian—named “Rocky” needs to pass a solid xenonite crystal to his human friend in a neighboring spaceship. The crystal is shaped like a regular tetrahedron, as shown below, and all its edges have length 1. To safely transport […]

This week the #puzzle is: Can You Pile the Primes? #primes #coding #BruteForce #oeis #subsets Suppose you want to make two groups with equal sums using the first N2 prime numbers. What is the smallest value of N2 for which you can do this? The answer is three! (Clearly, that wasn’t actually the puzzle.) The […]
