Change Word

Change word is a remarkably simple concept yet very addictive and challenging word game. The idea is to change one letter to create a different four letter word and continue until the time runs out. Just select a letter from the board and replace it with a letter from the keyboard.

The rules are simple too. You are not allowed to change the same letter consecutively and you are only allowed to use a word once per game.

How many 4 letter words can you create?
