Crossword Unlimited is a free Android game app developed by Havos Word Games that offers an unlimited number of tailor-made crossword puzzles. With this app, you can play crosswords in 16 different languages, including English, French, German, Spanish, Portuguese, Italian, Dutch, Swedish, Danish, Norwegian, Finnish, Polish, Hungarian, Czech, and Russian.

The app features a very configurable game generator that allows you to decide the grid size, difficulty, and many other things. You can choose from three different types of crossword grids: British, Barred, and Arrow. The app generates crosswords tailored to your interests, ability, nationality, and device size. You can zoom in and out of the grid and move around to play with large grids on small screens. You can also save and reload games, just like a crossword book, and use many aids to help you complete the crossword.
