Solvers That Run on Your Device

Most online solvers upload your puzzle to a server, wrap it in ads, or ask you to sign up. These don't. Every solver and analyzer here runs entirely in your browser using a real algorithm — backtracking for Sudoku, an eight-direction scan for word search, game-tree search for chess and the classics, and a constraint solver for Minesweeper. Your puzzle, photo or position never leaves your device, and there is nothing to install.

Frequently Asked Questions

Are these solvers free?
Yes. Every solver and analyzer is free to use with no sign-up and no download. They run in any modern browser on desktop or mobile.
Is my puzzle or photo uploaded anywhere?
No. Everything is computed in your browser. Whether you paste a Sudoku, photograph a word search or set up a chess position, the data stays on your device and is cleared when you close the tab.
What's the difference between a solver and an analyzer?
A solver finds the full solution to a single-player puzzle (Sudoku, word search, a maze). An analyzer evaluates a two-player game position and suggests the best move — like the Chess analyzer's evaluation bar and best line.
Do the game AIs really play perfectly?
Tic-Tac-Toe and Connect 4 use exhaustive game-tree search, so from a fair start they play perfectly — the best you can do is draw. Chess, Checkers, Othello and the rest use strong heuristic search, so they play well but not perfectly.
