Just had my two year old daughter beat me at this game. Thanks for destroying my self-esteem.
How many time / tries did she need to understand the game?
Did you give her any clues about how to play? Can she read some letters?
(Semi off topic: I don't know how far developed your offspring is, but my four days shy of two years old is only able to count up to three and recognize her own name when written down sufficiently large ;)
Edit: she's also able to mash key's like a perl programmer)
