Codeword Unlimited

Codeword Unlimited is a mobile puzzle game that recreates the classic codeword/cipher crossword experience with an endless supply of procedurally generated puzzles. Players decode numbered grids by assigning letters to number codes, solving crosswords without clues and relying on pattern recognition and a few starter letters. The app offers adjustable grid sizes (3–20), multiple difficulty levels including an early learner mode, and in-game aids such as letter reveals and candidate-word suggestions, making Codeword Unlimited a compelling choice for casual players, language learners, and fans of challenging word-based gameplay.
