    This article covers computer software designed to solve, or assist people in creating or solving, chess problems – puzzles in which pieces are laid out as in a game of chess, and may at times be based upon real games of chess that have been played and recorded, but whose aim is to challenge the problemist to find a solution to the posed situation, within the rules of chess, rather than to ...

    The remaining rules differentiate Heyawake from other "dynasty" puzzles: Rule 5 is the defining rule of the puzzle; black cells must be placed to prevent any (orthogonal) lines of white cells that cross two room borders ("spanners"). Numbered rooms typically provide solvers a starting place, among other deductions.

  5. Disentanglement puzzle - Wikipedia

    en.wikipedia.org/wiki/Disentanglement_puzzle

    Most puzzle solvers try to solve such puzzles by mechanical manipulation, but some branches of mathematics can be used to create a model of disentanglement puzzles. Applying a configuration space with a topological framework is an analytical method to gain insight into the properties and solution of some disentanglement puzzles.

    Smith discovered a 13-sided polygon in November 2022 whilst using a software package called PolyForm Puzzle Solver to experiment with different shapes. [4] After further experimentation using cardboard cut-outs, he realised that the shape appeared to tessellate but seemingly without ever achieving a regular pattern.
