# Magic number board puzzle solver in Python

The magic number board puzzle is yet another equation puzzle (similar to the first equation puzzle or Jodici) - but has a notable larger solution space. The magic number board is a quadratic board, consisting of 5x5 = 25 fields, which are organized as 5 horizontal rows and 5 vertical columns. Each field should contain … Continue reading Magic number board puzzle solver in Python

# Jodici solver: Python vs Prolog

Jodici is a fun and intuitive number placement puzzle. It consists of a circle which a) contains 3 nested rings and b) is divided into 6 cake-piece-like sectors. As with Sudoku, the goal is to fill in all numbers, while satisfying certain rules: each field must contain an integer [1,9], with each such integer being used twice in total. Further, each sector sums up to 15 and each ring to 30.

# Flower disk rotation puzzle solver: Python vs Prolog

The flower disk rotation puzzle consists of 4 wooden, stacked disks. The disks are connected at their center via a pole, so that they can be rotated. Each disk contains holes that are arranged around the disk center in the form of a flower. The holes are uniformly spread, so that there is space for 12 holes - but each disk only has 9 of these 12 possible holes (the position of holes differ per disk). The remaining 3 areas are instead made of solid wood. The goal is to rotate the disks so that all holes are covered by at least one of the disks (as we have a total amount of 4*3=12 solid areas for a total of 12 holes, each solid area must cover exactly one hole).

# Equation puzzle solver: Python vs Prolog

Our equation puzzle consists of 3 horizontal and 3 vertical equations. Each equation adds/multiplies 3 numbers between -9 and 99 to a single result number. The goal is to find all numbers for the still unset variables.

# Mastermind: code guessing helper in Prolog

You may know Mastermind, the 2 player board game where one player becomes the codemaker, who creates the code, and the other player becomes the codebreaker, who tries to guess/derive the code. A classic Mastermind board may look like the one shown on the left -- seen from the perspective of the codemaker, with the … Continue reading Mastermind: code guessing helper in Prolog
