Solve a Hidato puzzle
The task is to write a program which solves Hidato (aka Hidoku) puzzles. The rules are: You are given a grid with some numbers placed in it. The other squares in the grid will be blank. The grid is not necessarily rectangular. The grid may have holes in it. The grid is always connected. The number “1” is always ...

Smarandache prime-digital sequence
The Smarandache prime-digital sequence (SPDS for brevity) is the sequence of primes whose digits are themselves prime. For example 257 is an element of this sequence because it is prime itself and its digits: 2, 5 and 7 are also prime. Task Show the first 25 SPDS primes. Show the hundredth SPDS prime. See also ...

Smith numbers
Smith numbers are numbers such that the sum of the decimal digits of the integers that make up that number is the same as the sum of the decimal digits of its prime factors excluding 1. By definition, all primes are excluded as they (naturally) satisfy this condition! Smith numbers are also known as   joke   numbers....

Solve a Hidato puzzle
The task is to write a program which solves Hidato (aka Hidoku) puzzles. The rules are: You are given a grid with some numbers placed in it. The other squares in the grid will be blank. The grid is not necessarily rectangular. The grid may have holes in it. The grid is always connected. The number “1” is always ...

Chess coaches have been known to inflict a kind of torture on beginners by taking a chess board, placing pennies on some squares and requiring that a Knight's tour be constructed that avoids the squares with pennies. This kind of knight's tour puzzle is similar to   Hidato. The present task is to produce a solution ...
