Cat-Dog app for iPhone and iPad
Lewis Carroll invented the word ladder game in 1877. The idea is to take one word, and, changing one letter at a time, arrive at a second word. For example, going from cat to dog like this: cat -> cOt -> coG -> Dog.
Cat-Dog takes you on a delightful stroll in word-land with interesting pictures as guides.
Play it to learn how to spell, or simply to enjoy the puzzle experience and the close to 2000 images.
