Its a game that I found as a free app on my iPhone. I played for about 30 mins alone. The game is played by starting off with 4 letters and you try to decipher the word with the letters. You can use hints in the game to cheat, but you have a limited number of cheats. Once you clear a level, you move on to words with more letters. You start with 4 letter words and move on to 5 letter words and so forth.
I like these games when I can figure out the word, but scrambled letter games are not a strong point for me. I quickly dislike these types of games.
It can be an educational game. I can see where students in a Spanish 1010 course could enjoy this game style on a list of vocabulary words. This would help students learn to spell properly too in a different fun way.
