Solvers

The iqiqgame.com homepage is where you play puzzles. This page is the solver index: 17 interactive tools that take the puzzle in front of you and return the next best move, the full solution path, or every valid answer.

A puzzle solver is an interactive tool that takes the current state of a puzzle — its tiles, digits, cages or clues — and returns the next best move, a complete solution path, or every valid answer. Solvers work by computation and deduction, not by guessing, so a result is either a correct solution or a clear statement that the entered state cannot be solved.

A solver is not a replacement for solving. It is the fastest way to check whether you are on the right track, and the clearest way to learn the technique behind a puzzle you could not finish.

Yes. All 17 solvers run in your browser and are free to use with no sign-up required.

This page indexes 17 solvers: sliding puzzle, Sudoku, Killer Sudoku, Kakuro, KenKen, Futoshiki, Skyscraper, Takuzu, Sumplete, Mulplete, 24 Game, Make 10, Lights Out, Klotski, Mastermind, Wordle and Matchstick Equation.

Each solver works on any valid state of its puzzle. If the state you enter has no solution, the solver says so instead of returning moves.

Yes. Game pages are where you play a puzzle; this page is the index of solver tools that analyze or solve those puzzles.

No. Open a solver, enter your puzzle state and read the result — no account and no download are needed.

This index grows with the site: every time a new puzzle game launches on iqiqgame.com, a matching solver is added here.
