While playing Scrabble Junior with my son, I realized that he had memorized all of the words on the game board. In my head, I was thinking it would be great if those words word change, so he could learn new words. So that thinking inspired me to make a game called North Pole Scramble. It is play the same way, only the words are different. I made letter tiles, but I could have easily have used the wooden tiles from the game. I played it with my son and he loved it. I am planning to make some more thematic ones when I get a chance.
