About these puzzle solvers

Every tool below is free, works in your browser, and needs no account.

Will the Wordle helper spoil the answer?
It only narrows the word list from your clues — you still make the guess. Use it as a hint engine, not an answer key.
How does the cryptarithm solver work?
It searches digit assignments that satisfy the equation, respecting the no-leading-zero rule — and finds the classic 9567 + 1085 = 10652.
Can the Sudoku solver handle any puzzle?
Any valid puzzle, including notoriously hard ones. It also tells invalid puzzles apart from merely unsolvable ones.
